I use it for 6 months.

Its main attributes are price, rendering the sound generally correct for the price, and very good sound insulation. His faults are sound enough acid in the acute (it strengthens the sibilants and we naturally want to reduce the treble) and a more comfortable means (high pressure pad very hard, very limited set).

I also have a HD25, more comfortable when he isolation even better for the environment, but it is "just" four times as much.

For an affordable headset is very respectable, I would do this choice.
