Anyway, choose well your model (iPhone or Galaxy) and the color you want (black or white).
These headphones remind me a lot Sennheiser CX-400 that I bought there several years to equip MP3 players (they still work fine.) Some notable differences, however, as this reasonably complete with a remote control and microphone located very high, close to the ear (it's hard to look when wearing headphones - Fortunately, it is simple very easy to use, and the microphone close to your mouth ensures optimal quality for the speaker.) A point was however much improved, this is the cable friction noises that are very present here (although you can still decrease by looping around the pinna.)
The build quality seems good, but it should be careful and handle these headphones with care: cable and connector are thin and potentially fragile. Only the bare minimum is supplied with 3 pairs of tips, nothing else.
Audio quality side is convincing enough (again, performance is limited by the audio output that my phone is slightly noisy - the latest Galaxy are happily better provided on this point.) Tested on better audio source, quality is excellent. Please note a fairly straightforward bass enhancement, which the case for most of the ITE. The price / quality ratio seems honest.
