I purchased these after watching DTV on Tivo & the rave reviews. Personally I say they are they are OK the noise reduction is minimal in comparison the noise cancelling headphones from Sharper Image & I worked in a production setting with very loud machines. These also cancel all BASS via my Sony Walkman SRF-M85V; I'm not a Bass Junkie however a little would be nice. For the $$ try them before you buy them. If you like all Treble you'll be fine.
