so I won't be using these headphones like most buyers. Headphones at the first parties worked perfectly. They have good ambient noise attenuation, clean sound with a slight bass boost. Very comfortable, but I would better mark which is right and which is left, because in dark clubs you can't see these markings very well. Another thing is the length of the cable - it is definitely too short, but I was prepared for it and bought a suitable, dedicated extension cord with a small jack socket. I highly recommend them because they are worth the price.
