Used to be a fan of Logitech G5/G500 but I felt like I wanted something lighter, slightly smaller with more grip. Sound quality is very good and the volume level goes very high which is better than most. Ive been a long-time wearer of Keens. They sent me a new frame for the bike to solve this issue, however taking apart of the old bike has been a HUGE pain in the ass and am still unable to take the peddles off. Reminds me of zombies cod Once again the word "lush" comes to mind when describing the soundstage of these headphones. ) Con: it isn?t easy to put the bikes up, at least for me. Love how simple. I ordered one to see first if it?s as shown . I normally wear a size 10.
