Sound: Very impressive given the price. To me none of these really impacted sound quality. Very poor quality but functional I have one by my front door for jackets, I keep like 4-5 jackets or sweaters on it at a time. Had to buy a size smaller. it works fine for splitting headphone or speaker audio, but will not function while splitting audio and mic seperatly. It even includes optional P-clamps in case your bike does not have the mounting holes built-in. These earbuds have a very crisp sound. Fitting the shelves into the brackets holes took a little force. The play pause and rewind button was a nice touch as well, only I wish it was a little less tactile as when you actually do skip or pause a track, it feels like you are jamming it into your ear due to how hard you have to press the button.
