«  quality and price efficiency »

to have tried a lot of headphones, that suits me. generally, it is pretty much as the ears of those to whom I lent! So I think it's a good product, solid and reliable, and I recommend it to everyone in monitoring except for situations where a premium is required.

I use this headset for batteries made in studio (recording).
I paid a small price, I needed an enclosed headphone that would irremediably destroyed within 6 months of falls, uprooting of cables and other delicacies due to severe use.

First good surprise, we can keep long on the ears without hurt (I wear glasses). it's just sometimes a little warm.
Second good surprise, the sound is very decent, good enough musician to return closed.
Third pleasant surprise for me and it is vital: it is a closed headphone that "blocks" not the ears, with this sometimes confusing feeling when we lose feeling drummer game because of a too closed headphone fully isolated. provided few repisse in microphones around me.
8/10

After a year, he remained in perfect condition, it is very surprising given the speed at which I submit, then 10/10

the audio quality is good for the price, but do not expect to make a mix with it!
it supports heavy loads and responds well to low intensities, but it is not neutral.
nice, yes.
