| Review summary | Info unavailable | These small, cone-shaped earbuds offer excellent isolation and pro sound quality. | 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. | Ultrasone's full-size closed-back HFI-580 headphones create a private listening space between your ears. | The unique and stylish Monster Beats by Dr. Dre headphones offer solid audio, useful accessories, and a look that's anything but copycat. For fashion-forward folks with cash to spare, they're a great option. |
