Excellent headphones but I preferred the clearly SHE9700 / 10 (which has been discontinued, shame!) I found the sound much clearer and more balanced. The SHE9000 relies too much on the bass, certainly because of its Turbo Bass Boost (good for those who love!). But I insist, it remains an excellent article, comfortable, well insulated from outside noise and responding to a wide range of sound frequencies so that you remain very satisfied with his purchase. Kind regards. Aganpal25.
