Quality, rather pleasant. low or medium rather precise enough and present, without being bulky. the highs are very present, too (for my taste) if you use it with Apple PMP but correct if you have a custom equalizer intégré.j'ai could test them with different sources, and the results are quite convincing for the price (45). So little to say on the very satisfactory audio quality.
The disappointment is more concerned with quality headphones. the headphones are good, but after a month of use, I can hear the sound as if it was in the background and like a jack was pressed halfway.
Unlucky or insufficient quality of the cable (knowing that the product launch was much higher price), I recommend this product to half that of an audio point of view, is more than interesting.
