For music, probably not your best choice but would be okay. 5 to 2 inch reducer. While I like the smooth touchscreen capabilities, the head unit OS is disappointing. These are better made than average. For now, I?m glad I have it. I kept them to give them a timely trial, but I?m still disappointed. As a wearer of glasses, I always find comfort problems after a while, with all headphones I have tried over the years. another thing is that the wireless puck comes with the powerplay instead of with the mouse. I prefer Crocs over traditional sports shoes since the plastic/ rubber material shields my feet completely from boiling hot spills, but at this rate it is not lasting as long so I may have to reconsider. Beware that it probably wont fit most 16" bikes, even if you measure the dimensions.
