Ok with the previous opinion, this headset cord is wound.
You know you headphones, replacing the speakers, even close? Me neither. The ATH-M20 does not defend himself too badly. Good bass and treble for the media, well it's not too much. He did not piss too, is tough and quite bearable. Cash it well but too much volume it has a tendency to raise the high frequencies, it plays a lot of voices ... hence the need for levels of the monitors. But apart from these minor flaws, I finally get used to it even though I also eyeing.
Good quality / price ratio is undeniable.
