Amazing sound quality .. but ...

Unpacking no worries, the quality is good, the son seem crimped, a pledge of good behavior in time.
Note the presence of a control with microphone, works so carefree handsfree kit as well as a remote control to start / stop the music (iPhone anyway).
I will first flat because it're very bad we can not control the volume for both music calls for.

Otherwise, plugging headphones and testing various types of music, I must frankly say that the quality is restored bluffing, especially in the bass, where the original headphones are largely exceeded. Musically nothing wrong, for small headphones of this type, no regrets.

Why put only 3 stars suddenly? because in fact as soon as one is moving, jogging, intra will tend to come out squarely, and walking just means either friction of the cables on the clothes or the sound of footsteps is also transmitted, so actually for good musical quality must remain static .. so watch out, it's not that this mark, it must be the case for all listeners of this type, it's just a little disappointing. Take all these factors into account before buying, everything will depend on your use me for jogging again I bow my helmet (the same brand elsewhere ..)
