Not for little ears but very good sound

The sound quality of these headphones is amazing.
Net low and not drooling
Medium present (a bit back anyway)
Treble not too garish
A great mix for headphones surprising at this price.

The remote control works perfectly with a sufficiently large button not to hinder those who have big fingers :)

The complaints I have with these headphones:
1 / The weight bothers me a little. It ends not used to it but it's still a little surprising departure
2 / Even putting the smallest bits provided, I'm struggling to hold them. Note: I have the case with ALL models I tested. We must believe that besides having big fingers, I have small ears :)

The sound insulation:
For those who have never used in-ear headphones, be aware that they act as earplugs to isolate you from outside noise. It is very effective and allows you to not have to push the volume too high to isolate you from the outside.
Personally I have a little trouble with the side "water in the ears" that reminds me of the feeling of wearing these headphones, but in a noisy environment, there is not to procrastinate: it is necessary to wear! In this way, you isolate ambient noise and you will not rot your eardrums.

Summary: Excellent headphones, perfect insulation and sound quality well above what one would expect given the ridiculous price. Avoid if you have very narrow ear canals (but that does not concern many people). Comes with several tips to fit each. Quality that gives the impression of strength and longevity.
