Just took this out of the box and am using it as I write this review. I am very impressed with the sound quality of these headphones. I bought it to use while working on my work computer for listening to music, chatting with others, video conferencing and VoIP calls. At the moment I am very satisfied with the sound quality of the device. The bass is deep and rich, with no distortion. The manual controls seem to work perfectly at the moment, I hear parts of songs I've never heard before in 7.1 surround sound. The handheld remote is responsive and works great with responsiveness. I'll add a review after work. This will give me 40+ hours of continuous use and can better describe how it performed as intended.
