My only suggestion was that I do not really care for the red and blue color. Cheap but very low quality horrible fit Please help i spend all that money for gift and it comes empty small and medium sizes compatibility is different. And these, and also a pair of boots from Skechers, have been no exception. Way too big. battery life, ergonomic fit, and sound quality all fantastic for the price. Soon as I popped the back end of my mountain bike up there, down she went. So very positive first impressions about the product. This is a real problem, since I spend a lot of time scrubbing the dye out of my nail beds and heels!
