| Bottom line | This affordable model offers the detail and transparency of expensive high-end speakers. | The Audio-Technica ATH-M50 Professional Studio Monitor Headphones are among the best available for less than $200, offering excellent sound and build quality. | 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. | This affordable pro-style model sounds great at home and on the go. | Though they look a little cheap, the JVC Flats are lightweight, comfortable on-ear headphones that sound surprisingly good for sub-$15 headphones. |
