Bluetooth never did work properly. I am 100% satisfied and would recommend. What else not to like? :) They do tend to run a 1/2 size smaller than my actual shoe size. Finally, I really like the way the ear bud fits in my ears. But im still going to miss my bass. I got this controller because my old one was sticking. Ahora ni entra ni sale. Wish the whole thing was attached. Do not buy from here, you will be disappointed.
