Sennheiser Px 100 Consumer Headphones

i used the headphone with my n91 and was amazed with the quality of sound it produces and one would never expect the headphone which is quite lightweight and flat would have quality bass and clearity cause when i bought these i never thought these would have such deep bass form the way it looks.even at high volume level it sounds great giving all the sounds u have in a particular sond and we get to hear what the recording artist thought we would. i completly recomend this cause its cheap and for the money u pay its more than worth it keeping in my mind that this was the lowest range available is this brand.
