| Review summary | These small, cone-shaped earbuds offer excellent isolation and pro sound quality. | With the QuietComfort 3s, Bose has done a remarkable job of shrinking its popular noise-canceling headphones while achieving similarly impressive sound quality--but that engineering feat doesn't come cheap. | V-Moda's Bass Freq earphones are the perfect accessory for bass-loving Creative Zen Micro owners who are on a budget. If you prefer less low end, look elsewhere. | 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. | 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. |
