Query: This headphone has low sound quality and no Noise Canceling.

"Noise Canceling" definition on the Web = A technology that reduces the background noises but enhances the sound.What Philips HN100 has?- reduce background noise = NO,- enhance the sound = NO,- humming noise = YES, when "Noise Canceling" is ON,- bass/treble = very little,- suitable for MP3 player = NO, in fact even without the "Noise Canceling" you have to turn volume on your MP3 player to the MAXIMUM(yes, like 25/25 on my Creative Zen Xtra).
