The Bottom Line This affordable model offers the detail and transparency of expensive high-end speakers. While their sound and design may not appeal to everyone, the Panasonic RP-HTX7s are excellent entry-level over-the-ear headphones that are a good bargain. 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.
