The Bottom Line	For smaller headphones, the QZ-2000s provide impressive noise cancellation and big-bottomed bass.	Koss hit a home run with the PortaPros. Love or hate the design, there's no denying the sound quality here: they're the ideal companion for mobile audiophiles and home theater enthusiasts.	These macho headphones can rock out like pro models.	The JVC HA-NC250 Noise Canceling Headphones make a great travel companion for those who demand quality sound. And they may not be cheap, but they seem that way next to the Bose QuietComfort 3.	Sennheiser's versatile headphones sound great on DVDs and all kinds of music.
