| The Bottom Line | 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. | Despite their lightweight structure, the Sennheiser PX100-IIi headphones are surprisingly powerful, and we recommend them for travelers, students, and anyone else shopping for new open-backed headphones. | Priced less than the Bose OE2s, the comparable Sennheiser 238 headphones deliver good bang for your buck. | |
