Works great for my nearly 20 year old HD 580 precisions. Half sizes would have been great. Hit HARD BINNthe dark or light. Honestly the best earphones I?ve ever used. Really good quality as well. You dont need the app to use those features. Now first off I like this shoe a lot. I attempted to pay again, carefully examining my card and entering the information correctly. Maybe not the sturdiest wine rack, but it works perfect. -The product itself can be felt kind of cheap and light plastic, it holds very good into the table.
