The Creative Labs USB Sound Blaster Go! combines a set of Creative Labs noise-canceling headphones with the Creative Labs Sound Blaster MP3+ portable 16-bit sound module. The phones' noise-canceling capabilities were better than average among those we tested, easily turning the rumble of a large air conditioner into a soft hiss. They're light and comfortable, and they produce smooth, detailed sound that's especially snappy in the lower midrange and upper bass.
