enter these things. Im not sure what I was expecting, but what I got is an extremely clear sound while I remain fully aware of my surroundings during my walks and cycling. Been using these on a daily basis for a few months. I have knee problems & problems with my arch support. ??????????????????????????????????????????????????????????????????????????????????? You can download music or podcasts and lots of them. The platinum color goes with everything. So now if I want to install another seat, I need to buy a new bike. I also had a set of studio monitor speakers plugged into this unit as well as some other audio equipment such as a line mixer and a digital to analog audio interface. Just received this item and was disappointed.
