If you’d asked me three years ago which wireless earbuds to buy for the gym, I would’ve laughed and laughed and laughed. The entire category was so hilariously bad back then, how could I recommend anything? Well let me tell you friend: a lot has changed in the best of ways.
Update: Looks like Amazon sold out of the earbuds. If you're looking for an alternative, Amazon has the popular Klipsch Image S4i exercise earbuds for $39 for the next few hours, but those obviously aren't wireless.
