it is certainly not a bad headset, but the sound did not meet my expectations. I had in front of a Bayer Dynamic In-Ear Headphones and was very satisfied - especially I liked the clear sound at Bayer dynamic in which the bass had a slight overweight, this has, however, accompanied the sound and not destroyed. For my taste, the Jabra Vox is too much treble and the sound was rather distorted. The device scores definitely in terms of design, quality and fit and overall he is definitely better than the sound of the standard Apple headphones.
(Bayer Dynamic is defective after 1 year, ie Kland great - quality and design is not quite so)
