I use the headphones usually go on MP3 Player, but I've also already directly on the CD player (Marantz CD5004) and tested at the amplifier. The sound is very good and detailed, a little bassy (but is a matter of taste). The headset has a very high efficiency. That is, you can also easily make the ears broken if you turn out loud. Should we not, because he also quietly very good sound and very good outward shields, despite an open design. In my head it sits very comfortably and safely and not suppressed, even after prolonged use. But he is more suitable for larger heads. I have him. Almost on the lowest setting and am actually not very small The build quality is fine, a lot of plastic, but without burrs, etc. The integrated cracks in the cable controller and will not crack, and Contact noise is not also transmitted over the cable. I had to find in more expensive models. I can not say anything yet about the long-term durability. But if it is> 24 months, then that's ok for the price.
