Let’s face it: People at the gym aren’t bragging about their headphones. If they were that great, they’d be listening to them instead of talking about them. So while we’re sure those new PowerBeats Pro earbuds are something special, why would you shell out $250 for a tiny pair of speakers when comparable ones are […]
