The only complaint I could possibly have about these are that the tied ribbons are what keeps the sandal strapped to your feet and its a bit annoying to do them and undo them whenever I take them on/off. THERE i SAID IT! I only bought one to try but will be buying more. These are awesome headphones. it does NOT with the 2. Just don?t load a $50 made in China rack with heavy winter sweaters and then complain when it breaks. With some improvements for smaller phones this will be a great phone mount. Problem is theyre just not even in the same ballpark as the 471s. The material is also of good quality, breathable, a bit stretchy, and very comfortable. Throughput and compatibility are non-issues.
