I have Bose noise cancelling headphones...possibly the best purchase I have ever made since they allow me to basically turn off the environment when on a train (or plane but I commute about 1h each way daily via train so that's where they shine). My soundy friends tell me Bose sound quality is not in the upper echolon (my hearing is not fine grained enough to hear a difference so I don't really care) but the filtering is really amazing. Not surprised they improve on that and branch out a bit. I usually listen to stuff without vocals (X meets metal: https://www.youtube.com/user/331Erock https://www.youtube.com/user/331Erock) when reading as I can't concentrate if there's lyrics.
