It also charges really fast and theres an indicator light (which I REALLY appreciate) that lets you know when its fully charged. Easy to setup with both my computer and Blackberry phone. Glad I waited to write a review. Stopped working after 2 months. Are these comfortable? Yes, very. I had used Comply tips in the past for my bluetooth ear buds with great success as well so I was comfortable with purchasing these. I hit the print button, walk over to the printer and put a wee bit of pressure pushing the paper in until it fed. It stays on my foot, no slippage, and no binding middle strap across the middle. The installation instructions fail to mention that the two bars are different lengths, the longer one goes in the front. I wear 8 or 8.
