I'm new to the forum so please forgive me if this is in the wrong category. Lately a friend has been EXTREMELY pushy about getting the ROCCAT kave 5.1 surround sound headset which they seem extremely nice however I have my eyes set on the 558s because I want a great set of headphones for general use such has music, movies, audio/video editing/ gaming which from my research they are perfect for so my question is has anyone used both of these and if so what are your thoughts or would you have any other recommendations?
