Super comfortable. Great sound. Compared to my other KZ a ZSN Pro, the sound feels much wider(although it doesn't have too much depth) and you have a much easier time isolating specific tracks. In a way, it gives off a much more raw studio sound rather than a mixed track sound. Very interesting quality. Vocals are not as harsh on the upper mids and treble range and so therefore, vocals feel like they're placed a little further away. So it's much more comfortable to listen to music with singing. Compared to the ZSN Pro however, not as much impact on certain sounds. Especially in the lower range. But it still gives off some sort of mass for the lower frequencies so the bass is pretty decent (I'm a bass player too so I love bass). But as some others have mentioned in other reviews of this product, this set of IEMs is more for the detail in sound than for bottom end. There's plenty of detail in these and they feel super comfortable so you can wear them for very long periods of time. Others complain about these being too big. I guess I have big ears.Other than that, I really like these for their comfort, warm detailed sound, and not sounding so harsh on the upper frequencies so that singing can be listened to without discomfort.I have been loving the KZ line so far. I've slowly been trying out all of them. I may just invest in the AS24 version just to have the flagship of this entire line and see how it differs from this model.Side note, if you love lots of low end, these may not be a good fit for you. You should try out the ZSN Pro first. They have a much thuddier bass quality. You can hear the bass Drum fundamental more with those. With the AS16, you hear more of the detailed sound of the kick pedal hitting the drum itself. More detail, less fundamentals but still good mass in its sound. Again, really cool quality.UPDATE: While these IEMs sound incredible, I can't say much for their reliability. I've seen some people say that they ended up not working after about a year of use. Well mine lasted a little over a month. First, left side stopped working. I do have to give it to them for providing excellent costumer support however. Tried cleaning, switching cable sides, making sure my input jack is connected, played a very loud track, etc. So they finally sent me a replacement left side IEM which when it arrived, worked perfectly. I listened to music for about 5 minutes and then put them away in a case I carry them in. Later that same night, I took them out again and found that the right side had stopped working. After another email to their costumer support and stating that I would prefer to have a refund. They responded quickly, approved of the refund, and asked me to submit a video destroying the pair of IEMs(which I did) and they responded soon after. Surprisingly difficult to actually break these. Whatever plastics/resin they use, it's actually really tough.I did love the sound coming from these when they were working and if there are a few more revisions in the future to the point where these become reliable, I would definitely buy them again just because they're very convenient to wear and sound amazing. But right now isn't the time for then.

Don't hesitate to buy these. Use on the worship team-great fidelity and value

I've only played with them for an hour or so, but these check all my boxes... Clear audio, comfortable, and they stay in my ear. These are my first IEMs, and other than the proprietary KZ connector (0.75mm QDC), I'm sold.

Really cool earphone,economic, ,,,but,Not comfortable for my ears ,maybe that’s my ears problem,

So far, my son loves them. The fit, length of the cord and the quality of sound.

Looking for new in ears, I found these and purchased them. I must say, they sound great. I play drums and using them you can feel the low and mid frequencies very well, the high frequencies are clear and clean.These are must haves if you don’t want to pay top dollar.

I'm using these for in ear monitoring on stage in a rock n roll band. I absolutely love them. The bass is deep and rich while the clarity of the mids and highs sparkle just as they should. My only recommendation is get some foam tips if you want even better noise isolation.
