Helmet use for 3 years for acousmatic music composition.

headphone in good sound reproduction, very balanced.

Contrary to other opinions, I find the comfort of this headset very good, even after several hours of use. Very good isolation from outside noise.

However, I bought a new headphone (a sennheiser) more in line with the type of music I compose (monitoring requirement). Still, overall I recommend this headset especially since the price / quality ratio is pretty good.
