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

I just recieved these, I will update once I get a little more burn in time on them. I have a pair of westone um pro 30s that I am comparing these to. I primarily got them as a backup to my westones, which I use as IEMs for playing bass, but also wanted to see how good these sounded compared to a more expensive IEM with less drivers. These sound just as good as my westones, a tad bit more processed than the westones but might open up more with more time on the drivers. The included earbuds arent very comfortable, and the plastic body is a bit bulky compared to the westones, but then again there are more drivers in the KZs. However, for about a quarter of what I payed for my westones, these still provide a serious value to performance ratio. Seriously impressed.

Oh lord, the moment you realize youve missed out your whole life. If you think a pair of a thirty dollars Sony head phone is good, what you have been listening to was actually just decent stereo, which should be considered antiquated technology, as it is expected to progress in the last 20 plus years. Besides just sounds coming from left, middle, or right, I could hear notes in the entire directional spectrum. Bummer, left cable is now not working four months in.

These blow my $189 Westone AM pro 10s away. Incredible full sound.

These are amazing. Truly. I started with the KZ ZSTs as my first pair of in-ears after borrowing my bass players westones while I shopped for what I wanted. The westones are nice, but dollar for dollar, the KZs blow them out of the water. The sound separation on the AS10s is astonishing. Im a singer and use these for live events. Theyre worth every penny x10. My only complaint is the cable--not for quality, but for a fit quirk. On the ZSTs you get a cable that has a small wire inside it, allowing you to shape it to your ear as needed. On the AS10s, the ends proximal to the ear are encased in a preformed silicone, so theyre molded to a pre-determined shape. There is no altering this shape. It turned out to be fine for my right ear, but my left ear kept falling off. It actually wouldnt have been a problem at all if it had been my right ear, because I like to hear room sound on stage and so I almost always take my right ear out and use only my left. But it was my left, so it was infuriating. It wouldnt stay close around my ear no matter how much i twisted or repositioned or wrapped it in twist ties to force it to a shape that worked. I dont have deformed ears that I know of, but everyone is different so maybe it was just me. Or maybe it was just a slightly off cable. I dont know. But nothing worked, til I purchased an upgrade cable to replace it with. Now they stay on great (and I have an even better sound quality). Sending them back wasnt really an option because I am on stage multiple times a week and I didnt want to be without them AT ALL (because nothing compares, honestly). One thing to note: I got more foam tips to replace my comply tips that were falling apart, but actually found that I prefer the OEM tips with the AS10s (highly recommend foam for the ZSTs though). Heres why: They are all balanced armatures, with no dynamic drivers. Dynamic drivers displace air, and thus require a small hole to let the air move (which also lets sound in--and sound out). Balanced armatures dont displace air, and thus have no hole. As such, theres less noise pollution from outside the ear canal competing with whats coming out of the in-ears, and no bleed from a hole in the in-ear housing itself. So the OEM tips keep the sound isolated well. When I change to the foam tips, I just get a muddier sound, oddly enough. So I stopped using them and went back to the OEM tips. Very happy with the clarity.

Jazz sounds great with these.

Bought and tested a few IEMs today. This one is my favorite. Honestly I wasnt 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 its clean. Like the bass on Sennheiser HD 650s. Present but not over rumbly. I would recommend these over any of the cheaper models. The extra few bucks is worth it.

Bought these for my first pair of in-ears when I joined the worship band at my church. The sound quality is amazing and at such a great price! They are also very comfortable. Practices typically last an hour and a half at most but Ive used these for long hall practices for services such as Easter & Christmas (usually 3 hours minimum) and I didnt experience an ounce of discomfort! Highly recommend :)

Best headphones I’ve ever tried and I’ve gone through many pairs these are perform every other one on the market at three times the price

These were my go to headphones for the past two months, but the left side stopped working, and I can’t open the housing to fix it because of how tight it’s held together

Outstanding product
