Liberty Pro 2 looks good but its not made for sports right?
You can try find more reviews. I use the biggest ear wing support, can do jumping jack no issues. The reviewer also noticed the slight background static, guess he got the earlier batch as well.
Anker support is really upz, they just shipped a replacement for exchange.
