I listen to my music in a long time plopped on PORTAPRO Koss headphones (wired), which costs thirty euros. Most of the comments I read on this RS 220 prepared me for a sound revolution: it does not happen. This is a good helmet, yes, but if the sound is not significantly higher than the Koss, the price it is, and in a big way: 369 euros. Its ergonomics, moreover, is far from exemplary. In short, if you have a good cheap headphones, as I do not run headlong to acquire the alleged bombs hi-fi!
