Finding the ideal budget TWS

2023 was the year of the rabbit hole for me, as I ended up doing research on a variety of topics due to helping out friends and family with personal and tech issues. One of these rabbit holes that I ended up falling into was the wireless earbud(TWS) one, which eventually led into the more general rabbit hole of portable audio. I was really late to jump on this train, as everyone was on it when Apple AirPods were first released years ago.

I finally decided to get wireless earbuds for the first time at the end of last year(2022) during Black Friday. AirPods are easily the most popular choice for most people, but I decided against Apple for a number of reasons. The first is that I’m an Android user, and it’s widely known that many of the AirPod features don’t work on non-Apple devices.

I’m not new to using Apple products, as I have to (begrudgingly) use a MacBook for work and did have an iPod during my college days. While the iPod was good, I definitely remember how much I hated iTunes and how it was required to use that program to get music from the computer to the device. I also remember how annoying it was to get things fixed back whenever the iPod had issues. It just seemed like Apple was more interested in getting me to buy a completely new device instead of repairing it.

So even back then, I could already tell that using an Apple product when you weren’t already in the Apple ecosystem was going to be annoying. This is probably intentional. The whole idea of planned obsolescence never sat right with me too. And then of course, there’s the pricing. It really feels like they can get away with slapping higher prices on all of their products because of brand loyalty.

The last thing is that wireless earbuds are designed to be disposable products. They have most of the same components of a wired earphone, but due to being wireless they have an added bluetooth adapter and battery. That is a lot of tech to be cramming into a tiny earbud. The lithium ion battery is the biggest issue here, because it’s so compact which gives it a limited lifespan. On average they will last about 2-3 years, and once they die they are not repairable. It feels really silly to pay top dollar for a product that you know will not last.

So my philosophy for getting these is aim for something that is low cost, good quality, and will be reliable enough to last until the battery inevitably dies. I also feel that wireless earbuds should never be bought at full cost(since they are disposable products), and this isn’t so bad since they go on sale very often.

Tozo T6

Retail price is $40, but will often go on sale for around $25

Tozo T6 with a grand total of 6(!) different sized eartips, from XXS to XL.

These are my first! As mentioned earlier, I got these in 2022 during Black Friday. I picked these after reading a lot of reviews and doing some research, and seeing that Tozo products are some of the most popular on Amazon. The Tozo T10 is straight up the most popular set of earbuds on Amazon right after the Apple AirPods. I opted to go for the T6 model instead, after reading that these had the most compact and lightweight design out of their catalog. Tozo is an interesting company: looking at the broken English that was in the T6 instruction manual and seeing the big “Made in China” printed on the box, I thought they were a Chinese company… but apparently they’re actually based in Seattle, Washington. The T6 is a very old set of earbuds, as it’s already at least 4 years old at the time of this writing. But it was popular enough to get an updated version in 2022(bluetooth upgrade which improves battery life) and yet another update in 2023 with a new ergonomic design and added app support.

I got the 2022 version. These are honestly pretty barebones. But I feel like that works in the T6’s favor: it’s so basic, but that means it is clearly designed to work out of the box, no questions asked and no app needed. Missing most of the bells and whistles that the higher end earbuds have, but that’s ok because it does exactly what it needs to do.

That means these were pretty much perfect for my 1st set of wired earbuds. Just extremely simple and effective with a lightweight form factor and the most compact case I’ve seen. I’m not an audiophile at all, but I like the sound quality: it does have a boosted bass profile which is very common in cheaper buds, but it’s not excessive. The touch controls have just the right amount of sensitivity. The buds also have no ANC(active noise cancelling), but it is largely unnecessary because they have a deep fit(providing good passive isolation).

Honestly I would have been happy using these forever. The Tozo T6 had that combination I was looking for of being affordable, lightweight, reliable, and having good enough sound quality. But there was just one issue: comfort. The shape of the T6 makes it so that you need a deep fit to get a proper seal. Unfortunately that was uncomfortable for me, and I also started to get itchy and irritated ears every time I used them. Fit is one of those super subjective things, because everybody has different shaped ears. What is comfortable for one person can be the complete opposite for someone else.

So fast forward 1 year, and I start thinking about getting new earbuds to address the comfort issue. Black Friday rolls around again in 2023 and I notice that an audiophile company has recently released a budget TWS set.

Moondrop Space Travel

Retail price is $25, but will often go on sale for around $22

Moondrop Space Travel with 4 different sized eartips. Note that even if the charging case is inside the leather container, the sides are still exposed.

The Space Travel is unbelievable: it is the cheapest set of wireless earbuds I’ve ever bought, but at the same time it’s probably the best sounding. It does makes sense that it sounds way better than its price point suggests though, because Moondrop is a Chinese company that primarily markets their products toward audiophiles. The Moondrop Chu is frequently recommended as a beginner/budget wired IEM(in ear monitor), and the Blessing3 and Variations are very highly regarded in the audiophile circle.

Anyways I got the Space Travel because they have a lot of features(like active noise cancelling and a game mode that reduces latency) and I thought the visual design was clever. It also has a stem design which I was interested in trying out. True to its name, the case is modeled after a space shuttle which is really cute. Unfortunately even though the charging case looks really cool, it does not have a lid or side covers. I even got the extra carrying case, and with it on the sides are still not covered, which means that dust and lint will eventually get in if you carry these in your pockets. The overall case is one of those things that is really nice to display, but annoying to have to take out. It was also the bulkiest case out of all the TWS that I purchased.

The sound quality of the Space Travel is really something else though. It’s really balanced and clear, with a great degree of instrument separation. The noise cancelling mode works but is not top of the line, but I feel it’s acceptable considering the price point.

One quirk is that the voice prompts in the Space Travel are done by Japanese voice actress Mitsuki Yuki. You get to hear her say “Shhh~” when switching to noise cancelling mode, and you can hear “Hey!” when switching to transparency mode. It’s pretty cute and fits in with Moondrop’s brand of putting anime girls on their box art.

Unfortunately I had to go shopping again, because the Space Travel had the same subjective problem that the Tozo T6 did: comfort. I could not get a good, comfortable fit with these. I even messed around with all of the eartips that were provided! I had a good experience using them though and being down $22 wasn’t a big deal, so I ended up giving them away as a gift to my mom.

At this point I was convinced that my issue was with devices that use silicone eartips, which led to my next purchase.

SoundPEATS Air 3 Deluxe HS

Retail price is $60, but will often go on sale for $40

SoundPEATS Air 3 Deluxe HS. Charging case has a nice glossy finish, which unfortunately makes it a fingerprint magnet. Not pictured is a USB-C to USB-A charging cable

Hoo boy, where to begin with these. My experience using these was like a rollercoaster: I remember being completely blown away on the first day and thinking that I had found my perfect TWS set. Then over time I started to notice all of the issues.

I was sure that the answer to my problems was a TWS that were were not in-ear style and did not use silicone eartips. I would need something that was half in-ear, like the Apple AirPods. So I did some searching for AirPods alternatives and half in-ears, and the Air 3 Deluxe HS(along with the newer Air 4) kept popping up. SoundPEATS is a Chinese company that primarily makes wireless audio products, and they seem to have a decent reputation so I opted to try these out. I went with the older Air 3 instead of the Air 4 because I heard that the Air 4 was slightly bigger, and I really wanted these earpieces to be as compact as possible.

Since these don’t have eartips, they don’t form a seal since they sit on the very entrance of the ear. So I was very impressed at how great they sounded despite that. They felt super comfortable and didn’t plug up the ears or exert any pressure, which was something that the previous two sets did. I was in love with these the first day and thought that I had finally found my budget endgame. These have a pretty ridiculous name, and it’s because they are a 2nd revision! Originally there was the Air 3, which was popular enough to get an updated version called the Air 3 Deluxe(which added app support), and then finally the Air 3 Deluxe HS which added hi-res audio. Specifically, they support the Android exclusive LDAC codec. Unfortunately LDAC is kind of wasted on me since I primarily use mp3s and Youtube Music for listening. With a bitrate of 990 kbps, LDAC is the audiophile codec meant for lossless audio, heard in flac files and in streaming services like Qobuz/Tidal/Apple Music. The free tiers of Youtube Music and Spotify max out at 128kbps and 160kbps respectively, for reference. Turning on LDAC also eats up the battery, so I ended up never using this feature.

But yeah after this incredible first impression, the problems started popping up. The first one popped up fairly quickly: the touch sensitivity. The touch controls of the Air 3 Deluxe HS are hypersensitive. Instead of having a designated touch panel, the entire bud and upper portion of the stem are sensitive to touch. Because of this, it feels almost impossible to avoid triggering the touch controls when putting on/removing the earbuds. I noticed this issue the first day, but thought that the problem was caused by me being new to the product, and that it would get better over time. But it didn’t and if anything the problem got worse.

The Air 3 Deluxe HS was also the first earbuds I got that had in-ear detection, where it automatically turns off if the device is taken out of the ear. Just like the touch controls, this feature was also way too sensitive. Sometimes just opening my mouth or turning my head would pause the music.

I got super annoyed at this oversensitivity, so I went and downloaded the SoundPEATS app since I read that it could customize these features. The app has a nearly 1 star average rating on the Play Store which is pretty alarming, and after investigating it’s likely because the app requires turning on location services. Yikes. This is the first app that allowed a full custom equalizer, which is a huge plus. It also allowed me to turn off the in-ear detection. However I noticed that I could not customize the touch controls. Even worse, I had read online that the app is supposed to let you at least turn off the single-tap while keeping the double-tap and long press. Well there must have some update, because on my app I only have the option of leaving them on or turning off the touch controls completely. False advertising?

Settings in the SoundPEATS Android app. As you can see, the touch controls can only be turned on/off with no customization even though the app is advertised as being able to turn off the single tap function.

This problem became worse once I started taking the Air 3 outside. They have a loose fit which is nice for comfort, but they did not stay in the ears at all. I had them falling out even when going for a light walk around the neighborhood. So I would have to constantly re-adjust the Air 3, which would then trigger the touch controls. They also don’t any passive isolation at all since they’re not in-ears, so if I went anywhere remotely noisy like a cafe or restaurant, I wouldn’t be able to properly hear the music unless I really cranked up the volume.

It got to the point where the only way I could enjoy the Air 3 was to only listen to them at home in a quiet room, with the touch controls turned off. At that point I might as well use wired headphones or IEMS, since the main purpose of wireless is to make it more convenient to use outside.

I was pretty discouraged at this point, although I did get a decent deal on the Air 3(it was still Black Friday week so I got them for around $36). So it could have been worse. I still think the sound quality on these is really impressive, but there were too many usability issues. Luckily, my savior was arriving with the next purchase.

Anker Soundcore Life A3i

Retail price is $50, but will often go on sale for $35. These are also sold under the name “Life Dot 3i” at Walmart. Not really sure why there are 2 different names but they are the exact same product.

Anker Soundcore Life A3i, the budget and comfort god. Earbuds have an ergonomic, bean-like shape. Only 3 different sized eartips unfortunately.

I went back to the drawing board and did a search for earbuds again, this time adding in the words “comfortable” and “compact”. The Life A3i and the Space A40, both by Anker Soundcore popped up a lot. I was already familiar with the Anker brand since I use some of their charging accessories. For some reason I had always thought that Anker was a European company, but they are actually from China. At this point it was way past Black Friday, but it was Christmas season so there was a sale on both of these. I went with the Life A3i because I read that it had a slightly better battery life.

Completely blown away. Unlike the Air 3, the Soundcore app is EXCELLENT and actually does what it’s supposed to do. You get a lot of EQ presets along with the option to fully customize the equalizer. The active noise cancelling works well and is more effective than that of the Space Travel(though that should be expected given the price difference). The default Soundcore EQ profile of the A3i is actually not great, but that can be fixed very quickly by switching to the much better “Acoustic” EQ profile or just making your own custom EQ. Instead of touch controls, the A3i instead has clicky side buttons. It was a little weird at first, but after adjusting I greatly prefer it since I no longer have to worry about accidentally triggering touch controls. The app also allows full customization of the button controls including the single tap, double tap, and long press.

Most importantly, these are comfortable! They do have silicone eartips, but they have a shallow fit instead of the deep fit that I experienced from the Tozo T6. I have found that I prefer the shallow fit over the deep one since I don’t have to feel too much pressure from the earbuds plugging up the ears. The A3i has an ergonomic shape that fits the contour of my ears. They also do not make my ears itchy. Even with the shallow fit, these have no problems staying in my ears and they also have good passive isolation. If I really wanted to, I could wear these all day which is something that I definitely could not do with my previous earbuds.

Conclusion

And that’s the end of my journey! I’m really happy with the A3i and it has become my daily driver. Part of me is still curious about how the Space A40 sounds but I’ll maybe look into it later if these ever break down.

It does suck that I had to buy 4 different earphones before I finally got my ideal set, but that’s what happens when there are no brick and mortar stores that carry these around anymore. It would be really nice to test these out in person before buying them. And to think that this all started because the first set gave me itchy, irritated ears. One thing I learned from this is comfort trumps all when it comes to selecting your daily driver. If I was judging based on sound quality the Moondrop Space Travel would be the clear winner. But when it comes to comfort the Life A3i is the best here. I’m still impressed by how good of a starter set the Tozo T6 was though. Even though I don’t use it anymore, there are still a few things that I miss about it. I think the T6 had the best implementation of touch controls, and I love how lightweight it was. It had the most compact case too. I really appreciate the simplicity.

Random

Recently I’ve been playing EFZ again, after watching some of the new videos that the Kaori player Nagisa put up on his mylist. I forgot how hype this game was. Sadly, playing the game is a pretty mixed bag for me, probably because 1)I hate the command interpreter and 2)My character Akane is really really hard. Especially since nobody plays this game in SoCal anymore, I pretty much have to netplay it, so it just makes the experience really not enjoyable. The EFZ netcode was considered pretty good way back when it was first made, but it’s pretty dated nowadays with stuff like GGPO and Caster available. I wonder if the game would get a revival if there was an EFZCaster.

bell has recently been doing a lot of work on Mizuumi, nearly tripling the amount of wikis that were originally there, upgrading WordPress and getting a really nice theme, and restructuring the forums. It kind of inspires me to go work on my own sites more, since I’ve been neglecting them recently.

And some nice covers that I’ve found since the last update

Calc.
Vocaloid: Hatsune Miku
Music and Lyrics by: ジミーサムP(JimmyThumb)

うさ(Usa) cover

Calc. is a really cool song, but I haven’t really found any covers of it that really stand out significantly over the others. Usa’s cover is really popular, though.

Sing my Love
Vocaloid: Hatsune Miku
Music and Lyrics by: 40mP

【蓮】(Ren) cover

Sing my Love is a somewhat obscure song, though I never really understood the reason why. There aren’t many covers of it, and even though it’s originally written for a female(Miku), Ren does a really nice job with the song.

SPiCa -HPT ReACT-
Vocaloid: Hatsune Miku
Music and Lyrics by: Headphone Tokyo

MARiA cover

MARiA is pretty amazing, and she’s supposedly a professional singer under the name Mizuhashi Mai. I actually don’t like the original SPiCa that much, but this rearrangement is great.

ローリンガール (Rollin’ Girl)
Vocaloid: Hatsune Miku
Music and Lyrics by: wowaka

yonji cover, Guitar Rock arrange

I have no idea what this song is about, but it’s very popular and there are a lot of good covers for it. This is probably my favorite one, and the rock arrangement is a really nice touch.

さよならメモリーズ (Sayonara Memories)
Original Artist: supercell

irony cover

irony is a pretty obscure nico singer. Her most popular cover is for the opening theme of the Ore no Imouto ga Konna ni Kawaii Wake ga Nai anime, which shares the same name as her alias. Her voice has a really eerie resemblance to Gazelle/nagi’s, and if it wasn’t obvious in her other covers it’s definitely obvious in this one. I couldn’t even tell the difference from the original song from the first few seconds.

More utattemita

Some cool covers that have come out in the last few months

トリノコシティ (Torinoko City)
Vocaloid: Hatsune Miku
Music and Lyrics by: 40mP

ENE cover

I haven’t done any research as to what this song is about, but it sounds wonderful and ENE easily has the best cover of it. ENE is a somewhat obscure nico artist, as she usually covers some of the less popular songs. She also has a Youtube account under the name enedayo, and she actually responds to comments in English!

お断りします (Okotowari Shimasu)
Vocaloid: Hatsune Miku
Music and Lyrics by: あたたたP (AtatataP)

ろん(Lon) cover

Really cute PV, this song is hilarious. It’s basically FML the song. I’m actually not a big fan of Lon but this song was basically made for her type of voice.

輪舞-revolution (Rinbu Revolution)
Original Artist: Masami Okui

花たん (Hanatan) cover

Revolutionary Girl Utena was one of the few shoujo anime that I actually liked, and the great opening theme was probably one of the reasons why. Can’t think of anything else to say, Hanatan is a great singer and she does this song justice.

メランコリック (Melancholic)
Vocaloid: Kagamine Rin
Music and Lyrics by: Junky

ENE cover

My favorite Rin song, I’m not a big fan of the twins, but this song is pretty awesome. For whatever reason, most nico artists use a vocoder when covering this song, and I can’t stand vocoders, so ENE’s cover is one of those rare non-vocoder ones that happens to be really good. I think Usa’s cover of this song is the most popular, but I actually don’t like it that much.

Utattemita (Part 2)

Some of my favorite covers and originals are:
メルト (Melt)
Vocaloid: Hatsune Miku
Music and Lyrics by: ryo of supercell

ガゼル (Gazelle) cover, 3M mix

ちょうちょ (Choucho) cover, 3M mix

rockleetist cover, 3M mix and English translated lyrics

Gazelle’s version is the classic one and easily the most well known cover of Melt. Melt is a ridiculously difficult song, and it’s amazing how she can hit all the high notes during the chorus without destroying her voice. Choucho’s cover is also amazing, though her voice does falter a bit during some of the high parts. I also included rockleetist’s english cover because she does a good job singing it and the english translation is really good.

Just Be Friends
Vocaloid: Megurine Luka
Music and Lyrics by: Dixie Flatline

ちょうちょ (Choucho) cover

うさ (Usa) cover, Band Edition

rockleetist cover, English translated lyrics

Legendary Luka song, the song is about breakup if you can’t tell from the title. Choucho’s cover is my personal favorite, but Usa’s is also really good as I love the Band edition. Also posted rockleetist’s cover to see just how depressing the lyrics are! I could never have guessed how sad the song was before I read those lyrics, since the song is so upbeat. However, rockleetist did take a few liberties with the translation, since JBF is originally written from the guy’s point of view, but she rewrote the lyrics from the girl’s POV. Some people have a big problem with this, but I don’t mind it since sometimes it has to be done to keep rhyme and meter.

ルカルカ★ナイトフィーバー (Luka Luka Night Fever)
Vocaloid: Megurine Luka
Music and Lyrics by: samfree

実谷なな (Mitani Nana) cover

Luka Luka Night Fever is a eurobeat song describing her nightlife. I’m not a big fan of eurobeat(I can’t stand it, actually), but this song is pretty well written and it fits Luka rather well. This song got so popular that the people on nico actually went and created an elaborate dance routine for it. There’s also a vid of Nana Mitani herself trying to dance to herself singing it(by recording, of course).

初めての恋が終わる時 (Hajimete no Koi ga Owaru Toki, or Hatsukoi)
Vocaloid: Hatsune Miku
Music and Lyrics by: ryo of supercell

ちょうちょ (Choucho) cover

IMO the best cover that Choucho has done and the best cover of this particular song. Not much to say, it’s a beautiful song and Choucho’s performance is spotless as always. I’m not really sure what the song is about that, since the lyrics are kind of vague.

MEGANE
Vocaloid: Megurine Luka
Music and Lyrics by: ultra-noob

ゆず茶 (Yuzucha) cover

Megane is a fairly obscure Luka song. If you think girls with glasses are hot, this is the song for you. I actually don’t like Yuzucha very much, but her cover of Megane is pretty much perfect.

ブラック★ロックシューター (Black Rock Shooter)
Vocaloid: Hatsune Miku
Music and Lyrics by: ryo of supercell

ちょうちょ (Choucho) cover, Band Edition

Another legendary Vocaloid song from ryo, this song got so popular that there’s going to be an anime about it.

ggrks-ググれカス- (Gugure Kasu)
Vocaloid: Megurine Luka and Kamui Gakupo
Music and Lyrics by: Aamin-P

ヲタみん (Wotamin) and clear cover

This is a really cute song about a guy hitting on a girl on the Internet, asking her silly and personal questions, while the girl responds everytime with Gugure Kasu(Just google it, you moron). Tsundere Luka is delicious, and so is Wotamin’s performance.

ワールドイズマイン (World Is Mine)
Vocaloid: Hatsune Miku
Music and Lyrics by: ryo of supercell

うさ (Usa) cover

Quintessential tsundere Miku song portraying her as a princess falling in love.

恋は戦争 (Koi wa Sensou)
Vocaloid: Hatsune Miku
Music and Lyrics by: ryo of supercell

Fye cover

This is an intense song about Miku declaring that one must fight for love. The most popular cover of this song by a Japanese nico artist is Yamai’s, but I actually don’t like it all that much. I think the best cover is done by Fye, who is actually Russian. Her pronunciation is really good, though not perfect, but it’s her performance that blows the other covers out of the water imo.

ニコニコ観測(ββ) (Nico Nico Kansoku)
Based on the song 天体観測 (Tentai Kansoku) by BUMP OF CHICKEN

recog

This is a hilarious song about the life of a nico addict. I can totally relate to it since I spend way too much time on nico myself.

Super Mario RPG Rawest Forest
Based on the song “Rawest Forest” by Martin Hagwell, video by Kirbopher15
“Rawest Forest” an arranged version of 森のキノコにご用心 (Beware the Forest’s Mushrooms) on the Super Mario RPG OST

僕太 (Bokuta) cover

One of the coolest things ever. Rawest Forest was a song based on the Forest Maze music from SMRPG about the joys of playing the game. Kirbopher15 made a flash video of it that can still be viewed on Newgrounds, and this video apparently got so popular on Nico that people started covering it.

組曲『ウメハラ動画』 (Kumikyoku Umehara Douga)
Based on the song 組曲『ニコニコ動画』 (Kumikyoku Niconico Douga)

僕太 (Bokuta) cover

This is a hilarious song about the greatness of Daigo Umehara and his dominance in the fighting game scene. The song is based on the that big nico medley that was popular a few years ago. The modified lyrics were written by somebody else; Bokuta supplied the vocals.

Utattemita (Part 1)

歌ってみた, or utattemita, was something I discovered last year. It roughly translates to “to try singing”, and it’s the category on ニコニコ動画(nico nico douga) where people record themselves singing popular songs. So it’s like karaoke, basically. Supposedly in the old days, most people on utattemita did anime song covers, but nowadays it’s mostly Vocaloid songs.

I’m actually not a fan of Vocaloid at all. Well, I really like Megurine Luka, but I can’t stand hearing any of the vocaloids sing because well… they’re computer programs. No matter how good the songs are, it sounds terrible to me whenever that robotic voice is singing. However, Vocaloid is remarkable because it allows people with a lot of talent to create songs and share their works with other people when they normally wouldn’t have been able to, either because of the composer’s own inability to sing or the difficulty in finding a person willing to sing. Similarly utattemita is great because it allows amateur singers a chance to shine with some really professional sounding works(it’s not hard at all to record yourself singing and then layer it over an off-vocal track).

So I first discovered utattemita last year when I watched a really good Toradora Ami MAD, which can be viewed here. The song used in this video is “World Is Mine” sung by Usa. I was really interested as to who sung the song, so I did some research and the rest, as they say, is history.

Some of my favorite female singers in utattemita are:
ちょうちょ (Choucho)

Easily my favorite nico singer, she has a really pretty voice, amazing range, and she’s quite cute to boot. Her most famous cover is Miku Hatsune’s Last Night, Good Night, but I think the best cover that she’s done is Hatsukoi.

うさ (Usa)

Another fairly famous singer, her range isn’t on the same level as Choucho’s, but she’s a great singer and has some really good material. Her singing voice(which is somewhat high and cutesy) is actually really different from her normal voice(which is really deep), but there are some songs where she sings in that deep voice. She does doujin music work under the name Hana, and also has a band with Yamai, Tolie, and other singers called Usa Colony. Her most famous covers are of World Is Mine and Dear.

ヤマイ (Yamai)

Yamai is another very famous singer. She has a nice deep voice, but her range is pretty good and the image I get from hearing her voice is that of the beautiful older sister. She’s done a lot of Meiko covers in the past, which might be the reason why some people call her the real-life version of Meiko. She and Usa do radio shows together pretty often, and they act pretty yuri together. Whether it’s real or if it’s just teasing the fans will never be known, but it’s definitely delicious~ Yamai’s blog is also really cool because she puts up lots of WIP pieces of her songs, so you can hear how much they change in the final product.

ガゼル (Gazelle)
Gazelle is a legendary nico singer that unfortunately doesn’t upload any more covers because of some drama. She has a clear, beautiful voice, and has covered some great material. Her most famous cover is Melt, both the original and the 3M mix. Even though she’s quit nico, she still does work as a doujin artist under the name Yanagi Nagi. But most notably, she’s actually somewhat broken into the mainstream, being the vocalist for the group supercell. Bakemonogatari’s legendary ending theme is sung by her.

ヲタみん (Wotamin)

Not much to say… she’s a great singer, has covered A LOT of material and releases new covers pretty frequently. She seems to like singing Luka material. Her most famous song is actually a duet with clear on the song ggrks.

As for male singers
I don’t actually listen to male singers, for whatever reason… it might be because I don’t like any of the songs that were composed for the male vocaloids, and it feels weird to hear a male sing a song that was composed for a female vocaloid. So basically, all of the male singers I like are ones that do parodies or come up with original songs.

ヒャダイン (Hyadain)

Linked his user profile because there’s no mylist that contains all of his songs. Hyadain is hilarious and mostly creates songs based on existing videogame pieces. Most of his works have become wildly popular everywhere, evidenced by the sheer amount of Youtube vids of his works with foreign language subs in them. He’s a very good singer, and is also really good at singing as a female as well. His most famous song is his original composition about Street Fighter II, which incorporates various sound effects from the game and has him singing as every character in the game.

recog

recog is another great singer that mainly does parody songs. My favorite recog piece is Nico Nico Kansoku, a song about the life of a nico addict, parodying Bump of Chicken’s Tentai Kansoku.
