KZ AS10 IEM Headphone, 5 Balanced Armature Driver KZ Earbuds Wired Earphone, Stereo HiFi in Ear Monitor Headphone Musician Headset Earphone with Detachable 2 Pin Cable(No Microphone, Black)

Presentation of the KZ AS10: the box differs from earlier KZ models, the AS10 comes in a sober, elegant black cardboard box with the KZ logo and winged top, in which the IEM’s are placed in a hard foam support and labeled Left and Right, with a classy engraved plate with the KZ logo and the model description. The unboxing is pleasant The foam plate can be easily lifted with the attached black ribbon, underneath the foam plate 2 plastic bags containing the silicone tips (3 pairs in total, S-M-L , the IEM’s come with the Medium size tips attached), and the cable. Also included are the manual, warranty card and a small certificate of authenticity. The braided cable feels better compared to earlier KZ models, is not sticky, is flexible and have a good feeling to the touch, is clearly marked L and R at the plugs, 3.5 stereo L bending jack, contacts and jack are gold plated, the cable is about 120 cm in length, the KZ .75 mm 2 pin plugs connect seamlessly and easy to the AS10 IEM’s socket. The cable have a memory wire next to the 2 pin connectors covered in a transparent tube, the memory wire make a perfect fit to any shape of ears and help to keep the AS10 IEM’s in place. The shells of the AS10 are light weight, a little bit smaller compared to other KZ similar models, the nozzle maybe a little bit longer, what in my opinion make the KZ AS10 more comfortable to wear for longer times, shells are made from durable plastic, well put together, clean, without signs of glue spills, I got the black color model which have a translucent front and a black back, engraved with the model number and left and right marks. Isolation in this KZ model is also better than earlier models, and sound leak is lower than other IEM’s. When it comes to sound, is slightly V shaped, Highs are detailed, not piercing, maybe a little rolled-off, but without affecting the overall clarity, Mids are in the warm side, a little lower than neutral, female and male voices sound clean and crisp, Low ranges are well balanced and punchy with no distortion and don’t overpower the overall sound of the music and voices. Soundstage is wide and natural with good definition and separation of instruments were details are clear and defined. As always the appreciation of the sound quality of earphones is subjective and related to personal taste, I recommend to hear good quality recordings. I tried them with diverse musical genres with optimal result, my favorites are usually classical, percussion, electronic, jazz and vocals depending of the mood of the day. No distortion or muddiness was noticed. The KZ AS10 IEM’s sound good since I first tried, being a low impedance IEM’s they sound great with smartphones as well as music players. I used the AS10 with the desktop and laptop computers getting an excellent result in sound quality, this IEM’s also have an amazing volume level, I used them with Samsung, Nokia and iPhone smartphones and Mp3 players. In low quality recordings I used the help of equalizer to balance the sound, and it was well accepted by the AS10. Also watching a movie in the computer or tablet with the AS10 give me the sensation of being in a movie theater with a good surround sound system. As conclusion I can say that the AS10 is ahead of previous KZ models,with an clear and balanced sound and they can compare to more expensive IEM’s but having an affordable price, they are quality built and nice looking. I consider the KZ AS10 a must in any audiophile collection because of their capability to reproduce Hi-Fi sound. I am very pleased and surprized with the AS10 performance and comfortable wear. Because all the above-mentioned, I rate the KINBOOFI KZ AS10 with 5 stars

UPDATE to my UPDATE: I was so tempted to delete my first update... or this whole thing and start over out of pure embarrassment. I'm a professional and know sound, but apparently not my new laptop so much *insert eyeroll*. In short, since this whole review is far too long, I again stand by my original review on the 1st of 3 pairs of KZ AS10's; Incredible pair of iems. The 2nd pair, there was definitely something wrong with them. On stage and off there was a notable problem. The 3rd pair, I have admittedly not tried on stage yet (just got them today). I only plugged them into my newer laptop, and turned on Spotify. Although they were better than the damaged 2nd pair, something still wasn't right as I said. Something in the back of my brain was not sitting right with this however. I knew that my iems and other headphones I own could only be as good as limitations of the device they are operating from. Nothing I plugged into this laptop seemed to sound good. Didn't make sense. Its a new gaming ASUS FX705 laptop. The sound capabilities are going to better than others (one of the reasons I purchased it; for recording purposes). I fished, searched, Googled... and finally found it. Opened up the DTS HeadphoneX EQ and BOOM!!!! I jumped (iems were in my ears with music playing). Daaaang, now THAT's what I remember from the original pair of AS10 I bought! Superior stuff right there, y'all. So relieved. Let this be a lesson -- Your iems can only work their full potential if what you have them plugged into allows it. Now go plug these into something awesome and dance a little :) UPDATE: I stand by my original review of the (red) KZ A10's I purchased. Only problem is that I sold them to another musician because I decided I wanted the green color. No big deal, I thought. Sold them in about 5 minutes of posting, and purchased the new exact same pair in the green color. Received them quickly, plugged them in... but something wasn't right. That new pair seemed off and not as full as the pair I had just sold and used. I thought maybe I had gotten use to the first pair being completely burned in. so I burned the new pair in, used them on stage a few times, and finally had it. I took 'em home, plugged into my laptop and flipped on Spotify and realized the bass was not only missing as I suspected, but the top end was "raping my ears", as another reviewer so eloquently stated. I hoped that something was just defective with this pair, and sent them back... after ordering a $35 updated cord first to see if that helped. It did a smidge, but there was definitely something wrong with the ears themselves. I immediately ordered another green pair and they arrived quickly (Thank you, Amazon), plugged these new jobbies in and... yeah, No. The bass is missing again. Not nearly as bad as before, but for a 5 driver, its almost like the #1 & #2 bass drivers just aren't functioning, and seems to distort when any sort of bass hits. And, I don't mean like hip hop, thumping bass, just the normal range stuff. And once again, the high end also seems more abrasive than the original pair. Not sure what I am going to do at this point. I still think the separation and clarity of these iem's are amazing and unmatched to anything I've used before, however these bass and sharp treble negatives might outweigh the positives. Order yet Another pair? Try buying the Red color again and see if for some odd reason, they are just different??? They shouldn't be, but who knows. At any rate, after owning 3 pairs, I can definitely say they haven't been consistent which leaves me hesitant to recommend these anymore. Good luck, and I'm interested to see how this model plays out over time with other users. ORIGINAL REVIEW: I'm a musician and vocalist and I need iem's for their intended purpose... live/stage performance use. I stuck these bad boys in my ears the first time and wanted to just cry from joy and relief. I have owned and used some really bad trash and some okay but satisfactory ears in my time, and these are what I've been after but thought I couldn't afford. I don't have the cash flow for 1964's or UE's, and Westone 10's and Shure 215's have done the job just fine, but these KZ A10's are soooo much better AND Cheaper. I have, until now, not used such incredible sounding ears in this price range... or even several ranges above that. If you are on stage, in a band, you know how important it is to hear each instrument or voice clearly, cleanly, no muddiness. These do all that with detail I didn't know I missing before. There is ALSO a warmth that comes out of these that isn't fake sounding, overwhelming or mushy. There is just the right amount of Bass. I realize we don't want thumping subs in our stage iem's but it's definitely there and somehow doesn't overpower. I use these to enjoy my favorite Spotify playlists too and totally love them in this setting as well. The detail is amazing and I highly recommend these to anyone who needs quality but can't drop the funds for other ridiculously priced ears. -- Michelle

Balance sound signature. Value for money. I have used tin t2 pro which is very sharp compared to this, though this has warm sound signature and feels good. If you have any other expensive IEM, you should compare the sound with KZ AS 10 and see it for yourself.

Les écouteurs sont top, super son, plutôt bien équilibré. Je les utilisent autant en in-ear monitor pour la musique que sur mon smartphone pour écouter de la musique. Ils sont confortable et tiennent bien dans l'oreille. Bonne réduction du bruit ambiant.

Bought and tested a few IEMs today. This one is my favorite. Honestly I wasn't impressed by the sound signature when I first put them in. I found it to be a bit flat and recessed. The more I put them through their paces the more impressed I was. They sound good in all genres of music. They are very non fatiguing. You can listen to them all day without getting irritated. Yes they sound great. Good frequency response across the spectrum. They has less bass response than some of KZ hybrid models but if there and it's clean. Like the bass on Sennheiser HD 650s. Present but not over rumbly. I would recommend these over any of the cheaper model's. The extra few bucks is worth it.

Uso estos auriculares, como muchos otros músicos, para monitorización In Ear en actuaciones en vivo, y son espectaculares. No he probado gamas altas, pero no sé cuánto mejor podrán sonar, porque estos responden genial a todas las frecuencias, sin estridencias. Además, me encajan en las orejas muchísimo mejor que otros modelos de KZ. Recomiendo totalmente este producto.

Passt Super durch die anpassbaren Ohrstöpsel, Sound ist gut, Klasse nur zu empfehlen der Preis passt auch.
