Very good price / quality for so cheap I find it really great!
The sound is very good (as treble bass are qualities)
Very comfortable, the ear is not affected, so no gene even after several hours. The fact that the earhook or fabric that the ears have a little warm after 2 hours so a simple small gap to renew the air gives a spawning shot.
It is height-adjustable head clamp and angle of speakers thanks to a system that is not in direct contact with the head (so it never takes the same by setting the hair live on the head)
The cable solid air and is of good length (impec to plug behind the PC, then I have a little more than a meter of cable).
Quality micro level the same, the quality is very good, the microphone arm can rise or fall but not to bend at will, once she is still +/- 10 cm from the mouth but the micro well attenuates background noise to pass only the voice so I find this system better than the style industry "wire".
The branch of the microphone is semi rigid plastic (that's why it falls into place by itself), suddenly it gains in strength.
The head is not too serted from the headphones.
The top part that goes over the head (sorry not find the right word!) To a tissue cushion the blow it hardly feels the same and no gene after a full night of use.
The sound control dial on the left side is very convenient to access with the push to increase or decrease the sound.
There is also a switch above the sound adjustment knob that allows the drives to mute the microphone (down) or enable (upper position).
The only bad point is sound insulation, I think this is because of the cushion around the ears from the fact that it is hardly cloth cut outside sounds. Personally it does not bother me since I actually use at home so calm and sound environment without too much ambient noise.
Voila, you know everything, I would conclude by saying that after having tried several headphones still in this price range, this is the best I could find.
Hopefully my review will guide you in your best choice.
