Moondrop CHU II High Performance Dynamic Driver IEMs Interchangeable Cable in-Ear Headphone

I purchased these after my pair of noname IEMs died, since they're the top selling pair on amazon under $25. I use these to edit a podcast, and they work great and are pretty transparent. For the price, these things are an unbelievable deal. They sound great with both music and spoken word, they're comfortable for extended wear, and the all-metal housing is really sturdy. The cable is also really nice - it's thick and doesn't tangle easily. When these die, I'll probably just get another pair since I don't really want or need anything else. My only complaint is with static - it's winter when I'm writing this, and with the air being really dry, these have a tendency to give a very slight, occasional static shock when your ear touches the metal body. It doesn't hurt but you can hear it and it just kinda feels weird. Is it a dealbreaker though, absolutely not. Also, very minor thing, what's up with the anime girl on the packaging? It's kind of embarrassing when you just want some headphones, I get that some people like it but it's a super weird branding choice. Update after 8 months of almost-daily wear - I typically wear these in an office with only one ear in so I can hear what's going on around me, and I've noticed that the left ear (the one I would wear most often) has dropped in volume by about 80% while the right ear is perfectly fine. No idea what caused it, it just happened one day. I'm not dinging it any stars since it's still a crazy value for the quality you're getting, but don't expect too much longevity out of these if you wear them frequently. Update after over a year of near-daily use - these unfortunately died on me a couple of weeks ago. Wearing them in only one ear at a time, I noticed that the ear that I would favor would slowly diminish in volume in the last two weeks of its lifespan, and at a certain point it would fully die on that side. Then I'd switch to the other side, extending its life a few months, but the same thing eventually happened where the volume would gradually lower until it stopped working entirely. I decided to branch out and try a new set after these (the Linsoul Salnotes Zero) and the Moondrops are far and away the best build quality I've found in this price range. Sound quality is similar with decent clarity on both, but I noticed that these are tuned with a bit more bass and slightly more high end detail. So if you're using these in a studio or editing situation, I would maybe look for a pair with a flatter response. Otherwise, if you're using these for casual listening or really anything else, they'll sound great and last you a little while before you have to replace them.

TL;DR: How are these 20 bucks? They sound great and have an incredible metal build while being light and comfortable. Buy these. Wtf The Build: How are these $20… This is the most premium headphone I've ever opened and it was $20. T hey're insane. They are metal. They feel substantial in your hand, but light when you put them in they are so small and the fit is incredible, unsurprising for IEMs anyways, but I have some CCZ coffee beans that fit great but are bigger so don't enter as deeply, so these definitely take the cake. They have a leather pouch which is Primo, and not what I was expecting (I didn't see any pics beforehand). The eartips are pretty standard (no foam) and do a good job blocking out the outside world, it’s no active noise canceling and I’ve used better passive, but again they’re 20 bucks. The cable is a bit thinner than other IEM’s I have, and they don't have controls or a microphone. There is a slightly more expensive version with a thicker cable and controls and a mic, although its’ USB-C? Honestly I like the cable, it's light and more out of the way, and if nothing else I’ll just use a different cable from another set of IEM’s. The Sound: They sound excellent. I do think that the mids and highs are a little darker than I'm used to, but it's nothing that I couldn't fix myself with an EQ. They’ve very detailed, I'm running them with the BTR 5 and with Wavelet on and they sound pretty crisp. They're not the most clean I've ever heard, but definitely up there, and ESPECIALLY for $20. I do wish they were treblier, but I’m being picky at that point. I listened to a FLAC of AM by the Arctic Monkeys and they sound real good. I’m not sure what else to say about the sound, it’s dark and bassy, but it's nice and smooth; it’s unlike the bass outta some headphones I’ve tried. They do get loud. I've been listening to them at 60 percent without issue, they do get too loud at about 85 percent, if you’re into that sort of thing. The Music: FLAC - AM by Arctic Monkeys FLAC - Discovery by Daft Punk FLAC - IGOR by Tyler, The Creator Spotify - I Need to Start a Garden by Haley Heyndrickx Spotify - Locket by Crumb Spotify - Various songs by Mitski The Conclusion: I'm definitely going to be daily driving them at least for a bit, and again just an incredible package for 20 bucks (I'm excited for the leather pouch). I’m thinking these will be a great gift for friends. The Waifu: Excellent, my wife likes pandas lol

I'm not an audiophile or anything, but to me these sound pretty OK. Definitely not the best earbuds I have used in terms of sound quality but by far the best I have paid $20 for. Build quality leaves a little to be desired but its fine for the price. I tend to prefer wired earbuds for around the house and I used senheiser cx300 for a while. The sound quality on the cx300s is only marginally better than the moondrop chu II and it is over twice the price. Maybe that isn't a big problem for you but I guess I am pretty rough on my earbuds. I don't know when the last time I had a pair that lasted more than 6 months was. laying down $45+ each time for the cx300s didn't make me happy and last time I needed a replacement I figured I would try out some of the cheaper options and I had heard good things about this one. All in all its a pretty solid product but I'm not a huge fan of the around ear design and I would really prefer a braided cable. Then again, no issues with the cord getting pinched, etc. so far. I like the metal chassis but they are a bit heavy and I've had a few issues with it coming apart after I banged it on my desk etc. A few drops of super glue fixed that right up but something to keep in mind. I finally had to buy a replacement because I dropped my ipad with these plugged in and it landed right on the jack and bent it. It still kinda works but I have to jiggle it a bit to get it in the right position or the sound cuts out. Really its all about the price here. I mean $20 is $20 but I feel a lot better replacing these than some of the other earbuds I have owned and they sound... fine, which in this price bracket is an achievement. 7.5/10

By Hi-Tek HQ – Real Tech. No Hype. Let’s be honest—these aren't endgame IEMs. They won't make you cry in FLAC or hear ghost notes in Beethoven’s 9th. But they will make you do a double take when you realize they cost less than a pizza and sound better than some $80 hypetrash. I mean… think about what $20 gets you nowadays: • A streaming service you’ll forget to cancel • A gas station lunch that fights back • Or these—a pair of metal-shelled, Spring Tip-equipped, properly tuned IEMs that might just ruin mainstream earbuds for you permanently. --- 🔧 Specs & Build – Fancy on a Fast-Food Budget Driver: 10mm dynamic Impedance: 18Ω — easy to power, even from a potato Sensitivity: 120dB — gets loud enough to drown out poor life choices Cable: Decent quality, no microphonics and no you can't tow your car with it. Shell: Aluminum alloy—lightweight, sleek, and way too nice for this price Eartips: Includes Moondrop Spring Tips (seriously, those cost $10 alone) —Moondrop essentially gave you a free IEM with your Spring Tips purchase. It’s like ordering fries and finding a chicken sandwich in the bag. --- 🎧 Sound – Budget Harman Done (Mostly) Right ✅ The Good: Tuning: U-shaped with clarity up top and a tasteful bass lift. It’s not reference-grade, but it knows what it's trying to be. Vocals & Detail: Clean, articulate, surprisingly coherent. You’ll hear background layers you didn’t expect at this price. Treble: Bright, sparkly, mostly well-behaved. It tries hard to be impressive without stabbing you in the ears. Imaging: Narrow stage, but good left-right separation. Like a well-behaved studio apartment. ❌ The Bad: Bass Control: Starts tight, ends flabby. Play Kendrick Lamar – DNA at 2:00 and the bass gets messy like a toddler with pudding. Treble Peaks: Slight zing around 7–8k. Not icepick-sharp, but borderline fatiguing on long sessions. --- 🎮 Gaming Test – “Footsteps? Kinda.” Plugged into a Fosi K7, the Chu II handled ambient cues fine. In Hogwarts Legacy and God of War, you’ll catch enough detail to feel immersed. But in Call of Duty? Let’s just say: you'll know someone’s near. You just won’t know if they’re upstairs, behind you, or breathing down your neck with a shotgun. Not competitive-tier, but usable. For ranked or sweaty lobbies, use a something else instead. These are for chill vibes, not killstreaks. --- 🎼 Audiophile Cred – The Gateway Drug For new audiophiles? This is the gateway IEM that opens Pandora’s box. You’ll love it—until you start hearing its limitations... and the next thing you know, you’re buying a DAC, a stack, and justifying $300 cables to your spouse. For veterans? It’s your backup set. Your glovebox IEM. Your “hey listen to this” intro for friends stuck in EarPod purgatory. --- 💬 Final Verdict – Hi-Tek HQ Says: The Chu II is the kid who shows up to the gym with solid form, decent muscle, and great potential… but never does leg day. It’s admirable. It’s capable. But it’s not complete. Yet for $20? It’s criminal how good this is. If you have a heartbeat and two ears, buy it. Worst case? You score Spring Tips and get a free IEM in the box. 🟢 Buy it if: You want clean, confident sound with a touch of sparkle You’re just starting out in the hobby You want to gift something that makes people say “Wait... this is $20?!” 🔴 Skip it if: You crave thunderous bass or holographic soundstage You already own better and have no use for a sidepiece 🔊 Score: 8.3/10 – Honest value, slight flaws, big impact. 💼 Reviewed by Hi-Tek HQ – Come for the Sound.

Excellent excellent value. Great soundstage and clear highs and mids. My preference would be to have more bass. The packaging is good and it comes with a travel case. The wire is good quality and has an L shaped plug. The fit is very comfortable and it looks good too. Overall great design and crystal clear audio, fantastic value. Since so many people recommend this and the Crinicle Zero 2 so I bought both to compare. I would say the Zero 2s have much better bass but they are muddier and lower quality build. Moondrop Chu 2 is better for clarity and general listening but the bass is seriously lacking compared to the Zero 2. I gave the Chu 2s to my mom and kept the Zero 2s for myself.

These are great sounding IEMS for the price if on sale. They fit in darn near any ear type too! There are two problem . The ear tips that where included are a tight fit if not too small. The other thing is after a while one of my earbuds started fading until it ceased working. Moisture from the ear channel can build up inside the earbud eventually causing it to fail. It can come back after being left to dry so sorter listening sessions are recommended. I bought them for longer podcast and streaming sessions during the heat of summer instead of using my over the ear headphones. Over time with repeated moisture build up and drying one of the earbuds (left in my case) failed in a permanent state so for me the longevity was only 6-8 months.

I’m not a hardcore audiophile but I’ve used and own some “mid-fi” headphones such as the Sennhesier 6XX, 590S, AKG 7XX, Hifiman 400SE, etc. I don’t use earbuds much but needed to pick up a wired pair for an older device to use on the go. These Moondrops sound amazing. I hooked it up to my normal audio setup running it through a JDS Labs amp and basic EQ. The soundstage is wonderful. Crisp treble that’s not harsh, mids sound full and aren’t muffled. And the bass, they pack a punch and are nice and tight. At my normal EQ settings, it’s even a little too much so I had to dial it back a bit since I normally use my audio setup with Sennheiser headphones which lack a bit of bass. Stock bass on the Moondrop is more than enough without overpowering the overall sound. Fitment and comfort is great. Although I do use Azla SednaEarfit MAX tips which seal great and are super comfortable. For the price, I’m honestly surprised by how good these sound. I wasn’t expecting much but glad I gave these a try after seeing recommendations for them for budget earbuds.

I’m rating these 4 stars because while the sound quality is top-tier, the overall experience is "good but not perfect." The material of the shells is impressive they feel solid and premium. The color and finish are also very sleek. In terms of compatibility, they work great with all my gear. However, the cord is where I have some notes; while the cord length is standard and practical, the cable itself is a bit prone to tangling. The adjustability is decent since it includes different ear tips, but achieving the perfect fit took some trial and error. Great dynamic performance for the price, but the cable quality keeps it from being a full 5-star product for me.

Le Moondrop CHU II sono cuffie in-ear di qualità sorprendente per il prezzo. L'audio è chiaro e bilanciato, con bassi presenti ma non invadenti e alti dettagliati. Perfette per ascoltare musica in modo immersivo senza spendere una fortuna. Il design è elegante e confortevole, e il cavo intercambiabile è un plus che aumenta la longevità del prodotto. Anche dopo lunghe sessioni di utilizzo, rimangono comode da indossare. Se cerchi IEMs ad alte prestazioni che offrano un audio di qualità superiore senza svuotarti il portafoglio, queste cuffie sono un'ottima scelta. Consigliate per audiofili e non solo!

某動画で実機の測定結果も踏まえて「特性は高級機と遜色ないし左右差等のバラつきもなく性能的にはこの価格で全く不足ない」とお勧めされていたので購入（セール中\3900） イヤホン購入は久しぶりですが、この価格でこのビルドクオリティと充実した音質は凄いですね やや重い金属筐体で質感は価格以上ですし、わりとゴツいのにそこまで装着感も悪くない ステムが極太で付属イヤーピースが無理やりねじ込むような装着なのでやや注意 自分はスピンフィットNEOに交換して使用していますが、こちらのほうが装着に余裕がありシリコン素材のフィット感も快適なのでお勧めです ケーブルはかなりクセが強く絡みやすいのでこちらも適当なものに交換（上記イヤーチップと合わせ\3000程度の安物です） 音質の方ですが、測定結果だとハーマンカーブをほぼ再現した優秀な特性となっていました 実際かなり鮮明で密度感もあり聴いていて不足感が全く無い充実した音質 自分は基本スピーカー派でイヤホンのセコい音と脳内定位は好きではないのですが、こと音質に関してはこの格安イヤホンで全く不満がない時点で優秀性を実感出来ます 個人的には「ちょっと中低域の量が多い」とは感じますがそこは好みの問題 測定結果で判明してる理想に近い特性に対して自分がどう感じるか？がわかるのも自身の嗜好が理解できて面白い やや凹型で高域寄りの特性なので、中域強めが好みならイコライザーでその辺りを変えると良いかと ただスマホ直刺しや低品質のイヤホンジャックへの接続だと全く評価が変わるので注意 ヘッドホンアンプを通した音とは雲泥の差なので、この製品本来の性能を味わいたいならある程度のアンプ性能がある機器で使いましょう 音源の差もかなり明確に聴こえるので、良い音源・良い機器で聴くほどに質が上がり、それに追従できるだけの性能があるということです ただオーディオ環境に興味も投資もしない人にとっては若干鳴らし難い機種と言えるので、使用環境によっては本機より感度が良く鳴らしやすい機種をお勧めします ほぼエントリークラスと言っていいこの価格でこの音質と所有満足度すら感じれる質感 実機測定で証明されている高性能が手に入るのは凄い時代になったものです 流石に付属品の質は褒められた物ではありませんが、そこは自分なりにカスタマイズすれば良いし、それも楽しめる人には文句無しにお勧めです

Amazing for the price. Kept seeing getting praised and hyped up as a budget iem and im glad it actually lived up to it. Build quality is amazing, with a full metal body and cable is also decently amazing. 10/10. Definitely will take good care of them.

Very well tuned and an overall improvement from the first generation chu, to my ears. Moondrop has bumped the bass and smoothed out the treble, resolving the slightly metallic timbre of the first gen chu. I never had an issue with the amount of bass on the originals, but a lot of people did, this should fix that. These are now what I would describe as a slightly v-shaped sound signature, but it certainly still manages to remain articulate and engaging, very fun! Vocals are still a strong point, albeit maybe very slightly recessed compared to other Moondrop products (non issue), bass and slam is well controlled and treble has nice sparkle. No more spring tips included, just the standard Moondrop tips, and the nozzle now screws off allowing you to easily replace the filter. Moondrop filters are known to clog up with condensation/moisture resulting in channel imbalance, but I have yet to have this issue with any of my Moondrop iems, maybe I’m just lucky, maybe it’s worse in humid climates. If you do encounter this issue I believe either sucking on it lightly (seriously) or replacing/cleaning the filter will work to fix it for the time being. They also fit great in the ear. Like the chu 1, they’re small and don’t interfere, but don’t sit as flat as something like the Aria would. Remember, these are less than $30, have removable cables (a nice one too, imo), sound good. They make a great gift, too.

I received my Moondrop Chu II three days ago and tried it right away, but in my opinion, the sound quality was mediocre and nothing special at first. That was my initial impression, and since I know some headphones or IEMs need time to “burn in” before they show their true sound, I decided to burn them in for about 24 hours using the songs I usually listen to. I don’t like using synthetic audio for burn-in. I know some people don’t believe in burn-in and think it’s just the listener getting used to the sound, but in this case, I burned the IEMs without listening to them at all. After 24 hours, I can understand why many people recommend them. So if you own the Moondrop Chu II and feel that it sounds unremarkable at first, you might want to try burning it in and then listening again. Ideally, use the songs you normally listen to and keep your usual volume level. The one thing I don’t like is the cable, it feels too thin and seems like it could break easily. Buying a new cable with a 4.4 mm plug almost costs as much as buying another Moondrop Chu II, but I’ll see. I may still buy a better cable so I can use it longer. Now for the pros: the build quality is amazing. When you hold the earbuds themselves, you wouldn’t believe they only cost 219 SEK, 19.96 EUR, or 23.15 USD. The sound also improved after burn-in, the bass is sufficient, the treble isn’t harsh, and because of the V-shaped tuning, the vocals in some songs may not be very clear, though this might improve with more playtime. If you’re looking for your first IEMs, the Moondrop Chu II could be a good option. There are plenty of reviews, and many reviewers use the Chu II as a comparison point, which means it can serve as a useful benchmark if you decide to buy more IEMs in the future.
