I brought these headphones over 10 years ago after doing several reviews. The sound is phenominal- 5-30,000 HZ- Check the specs on any audio you own- 5HZ is almost unheard of for the low end. The sound is very balanced and you'll hear instruments you never heard before. The second thing that makes these so good it that they require low power and can be powered from any ipod. This is my second pair since the other one is getting old and I don't want to loose out on having these years down the road. I'll put these up against any of the new ones- even the "noise cancelling" ones- other than maybe on a plane- don't have the 5-30,000- and balanced sound that these do.
