User Review: These headphones are everything one could want and beat out anything in the price point. Very affordable, very comfortable, VERY sturdy, and most importantly, the audio quality is superb. I can put my phones on for hours and barely notice them, even with my large ears. These phones go with me everywhere, so they take a pretty serious beating day-to-day, and I've only just started to notice the slightest signs of wear after almost a year of ownership. Use them in the studio as intended and they could last forever. To more precisely describe the audio output on these headphones, I would say music is * accurate.* Bass isn't overpowering, nor whimpy. High notes are notable without being screechy. Distortion even at high volumes or the highest and lowest pitches is nonexistent. The super long cord is also something one would love in a studio, though it can be a minor hindrance in daily use. Another very slight drawback is that nothing is easily replaceable, but the cord is very heavy duty, the headband sturdy but flexible, and the ear cups seem to hold up well. That said, should anything break, either you have to deal with it or buy a whole new pair. Overall, I LOVE these headphones and recommend them to everybody from audiophiles to joe-schmoe on the go.
