Input:
I do not like traditional style headphones and the plugin-style ones are too painful for my ears, so I decided to try these. They are very good, no complaints. It is hard for me to judge sound quality as some other reviewers do, these are the headphones for a person on the move, not at home, and while on the street you usually are not in a silent environment, which means external sounds provide some interference. So whoa cares about 20 kHz frequency bans? Also, the cord is quite long which I like.
