| Bottom line | As far as really inexpensive headphones go, you're not going to do too much better than the Panasonic RP-HT21s. | Though they look a little cheap, the JVC Flats are lightweight, comfortable on-ear headphones that sound surprisingly good for sub-$15 headphones. | 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. | For under $10, you'll be hard-pressed to find in-ear headphones that sound better and are more comfortable than the Panasonic ErgoFit RP-HJE120s. | 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. |
