| The Bottom Line | Ultrasone's ultrapotent headphones have a rock-and-roll heart and offer exceptional DVD performance. | Ultrasone's HFI-2200 headphones score well on every count: they're comfortable, well built, and sound great. | Sennheiser's versatile headphones sound great on DVDs and all kinds of music. | 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. | The AKG K 702 Open Back Dynamic Reference Headphones offer an ultracomfortable way to enjoy sound that is remarkably more open than most sets; they're like personal speakers for your head. |
