### ⭐⭐⭐⭐ Exceeded expectations

### ⭐⭐⭐⭐ KZ Doing What KZ Does Best - AFFORDABLE QUALITY AND INNOVATION
*by S***. on 23 June 2025*

They are amazing for the price, they're comfortable despite falling out of my ears (I use the large tips with y smaller ear canals for more BASS), The clarity is good, the tuning makes many songs sound more warm or "live" which may or may not be what some are looking for, they do not have the balanced armatures so some highs are not as clear as they could be, but at least they dont sound tinny or leave me with tinnitus at full volume. I love these headphones so much I actually bought them because it was cheaper than just a replacement wire for my KZ ZSN pros, but now these are my daily drivers. I love the abiliy to "tune" them on the fly with the dim switches, I personally have the first 3 up, and tune further with my EQ on device. I'd give it a 5 star if the cable didnt keep getting tangled up, and if the mic button actually paused songs on my phone, but those are small nit picks. TL;DR: BUY THESE, they're worth it, even as backups that you may decide to run as dailies.
