Overall Rating: Star FullStar FullStar FullStar FullStar Empty ( 27 reviews )
  1. Star FullStar EmptyStar EmptyStar EmptyStar Empty Posted: Jul 21 2009

    These headphones are AWFUL. Yes, the construction is excellent and they are quite comfortable considering they're girth, but the bass is NON-EXISTENT. I tried them out right out of the box with my iPod, first with some Public Enemy and then some Guns n' Roses. They failed both tests epically. I didn't even bother to run them through some classical or jazz, since, even at high volume (both on the headphones themselves and my iPod/laptop) there was an abysmal response. Don't waste your time. I'm returning them right after submitting this review.

    I needed some way to fill my "mowing time" with more than watching the landscape go by. These headphones and my I-river (prehistoric Ipod type device) allow me to listen to NPR programs or music with good fidelity, while attenuating the mower noise even better than earplugs. I'm entirely satisfied with these headphones.

    These headphones block outside noise better than any other headphone I've worn since I was a little kid and they had those huge 70s headphones. I'm a mobile dj and these are great for cueing up and listening to possible next tracks without blowing your ears out. Often with other headphones the music from the speakers would be so loud that I'd have to turn the headphones even louder to drown out the music, by the end of the night my ears would hurt and I'd have a headache. These provide a seal over my ears that blocks out an incredible amount of the noise around me. I just put a little bit of the track I'm playing in the headphone mix so I don't miss any transitions. My only problem with these headphones is something that has been said in some of the other reviews and that is the lack of bass response with these headphones. You can hear very, very little bass in these headphones. But, the trade off of the incredible noise reduction and the great guarantee Koss offers makes them a four star for me.
