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. Though they look a little cheap, the JVC Flats are lightweight, comfortable on-ear headphones that sound surprisingly good for sub-$15 headphones. The Audio-Technica ATH-M50 Professional Studio Monitor Headphones are among the best available for less than $200, offering excellent sound and build quality. While they're not in the same league as the step-up ATH-M50, the Audio-Technica ATH-M35 costs a lot less and offers impressive performance and decent build quality for the money -- plus it has the fold-up element that's missing from the ATH-M30. You may be fooled by their featherweight design, but the MEElectronics HT-21s earn our recommendation for their ample soundstage, subtle aesthetic, and portable convenience.
