KZZEX Earbuds 1 electrostatic + 1 Dynamic Earphone in Ear Monitor Headphone with Detachable Cables Suitable for Audio Engineer, Musician (Black, with Mic)

Good quality sound

Sounds like all fz are boosted

Great quality. I would recommend it to anyone looking for good sound quality without the high expense.

The other 5 star reviews on these were correct. Accurate sound reproduction, w/o any peaks/valleys. And NO bass boost. But proper cups and fitting into ear canal is a MUST DO, or lows will be reduced, resulting in 'bright' or 'tinny' sound. I tested with port. CD player, and Triumph's "Fight the Good Fight". It blew me away. People not used to good quality mid's and highs may be confused, but don't be. You are just hearing what you've been missing. I would have been very happy with these, if I had paid double the price. It has a hefty-duty cable, and comes with 4 different sized earcups.

Para instrumentos y monitoreo son muy buenos, tienen una potencia muy alta, y se escuchan muy bien, por el precio no hay mejores, aunque deberían venir un poco más largos

I have purchased and listened to many IEMs and really enjoy these. There is a level of depth, bass and resolution I did not find in much more expensive options with supposedly better performance. These are some of my favorite IEMs so far.

All I can say is wow . Good job KZ. Some how they pull off a analog tone with digital music guess you would have to be in your 60s to understand what I am talking about .Ive tried to explain to my kids what they listen to music on sounds like compress garbage compared to the old 70s hifi audio. Some how these little rascals bring that sound back .Classic Bob Seger ,Fleetwood Mack,Eagles , Simply Red sound amazing just to name a few. Would I buy again heck yea
