I invested in this headphone wanting a headset, and also a headphone for night play on my synth Yamaha S90. Purchase in December 2008.

As a whole the headset is beautiful, it covers both ears, comfort is nice for a while, but after a few hours, it relies a bit on the head.

First listen, lots of bass ... The ear gets used to the long, upper spectrum is nice. Plugged into my synth, there comes disappointment, the very present bass transform sound into a real yogurt. Impossible to work on the lower half of the keyboard and whatever sounds.

I think therefore change this headset shortly ... shame
