I hear now for 18 years to music when I'm traveling. Accordingly, in my few players (2 Walkmen, 3 and 2 Discmen MP3 player) and especially many headphones have (had stopped counting) made an appearance and a finish. The latter had either a volume knob, bass boost, or any other technical stuff, which probably seems to be necessary for many people. But these headphones that come along without all extra frills, outdo all that I had previously. Urgent purchase recommendation!
