Koss KSC75 Consumer Headphones

Best 15 bucks I ever spent on headphones. Sound is full and both highs/bass are there. I own a pair audiophile's grade Sennheisers (590), and from sound quality these Koss are not that far for 10% of the price. The worst is that I have to push them to my ears to get the best bass/frequency response. It could be my physical ear layout, I suppose.
Getting these on is a challenge that requires two hands. I hold the clip with one hand while pulling my eart through with the other. But once they are on they are OK. I have less fatigue on my ears than from heavily padded Senn's. I can wear these for 2-3 hrs no problem.
For MP3 these are a great buy. I have a Samsung player, and at 192 kbps the sound detail is not different from Senns. It takes a mastered CD to tell the difference.
