I've had about 5 years. sound has matured over current! Sony, Panasonic or behringer .. but it is a surgical precision ... it sends exactly the sound mix and the original, but with a little lack of bass anyway. it is above the 240 because it has a 4hp .. it is rather heavy, and her old look is "rtro" .. but what a happy by taking her! (Guitars, basses, synths and voice, on this last point, he excels!) A brief headphone super pro, unflattering, but true .. (Hence the name high Fidler!) Brief references a large headphones for professional use. adconseiller but a little to a recreational use, daily, or mp3 dj. in addition, it costs candy!
