Summary: After a few hours, the tips of my hears start to sting and I must take a break because these are tight-fitting headphones. I could see that being both a good and a bad thing depending on your usage/preference.
Pros: These sound great, the cord is long, and I suspect the three modes are useful for DJs (High Pass/Low Pass/Normal).
Cons: The cord is kind of funky. For one, the hole is square where they plug into the headphones so you can't use a normal, rounded 3.5 mm cord.
Summary: If you love music as much as I do then you'll love these headphones... It's music to my ears.. pun intended.
Pros: I listen to music for several hours a day and am never satisfied with the sound that comes out of most headphones, but the sound quality on this is amazing. You're able to pick between 3 sounds Normal sound, mono and extra base. Even with it being on the mono setting it sounds better than my old headphones that I paid $80 for so an extra $20 was well worth it. It rests comfortably on my ears and blocks out ALL other sounds around me. You can turn off the led lights if...
Excerpt: They sounded alright, really crisp highs, but they need to be driven with some volume to get some bass out of them. Trying to use them on something like an iphone is not going to push them hard enough to be loud for good listening.
