| Bottom line | Sennheiser's HD 700 isn't just one of the best-sounding headphone models we've tested, it's also remarkably comfortable to wear for hours at a time. | Sennheiser's exquisite HD 800s sound more like listening to full-size speakers than any other headphones we've heard to date. | The Audio-Technica ATH-M50 Professional Studio Monitor Headphones are among the best available for less than $200, offering excellent sound and build quality. | They may cost as much as a big-screen TV, but the PS1000s are simply the best-sounding, most comfortable, and best-looking Grado headphones we've ever tested. |
