I was highly skeptical with the price point being so low and I set my expectations very low on these IEMs. Shipping was surprisingly fast and I received them within a week of ordering. They are packaged nice and the stock configuration fit my ear canal well. The sound is incredibly awesome and I think sound better than my high end Westones. The only complaint would be the fit of the wire over my ear. It sits out a little far and does not allow the cable to tuck behind the ear very easy and is why I knocked a star off of the review. Again, they sound great and listening back to a live show recording the Kick and bass really come alive. Cant wait to try them live.

Amazing and great fit.

KZ AS16 PRO X - 16 Drivers IEM Earphones

The headphones are of very good quality, the sound is good. They are a little big but even in these conditions they fit well in the ears. I would have liked the cable to be stronger, the part that goes behind the ear to be firmer and to have something on the cable that helps you lock the cable when you fix it behind your head.

These KZ AS16 pro are way to big for my ears.
However - They Sound very good.
