Editor’s Note: This review was first published on 1/31/15, based on what proved to be a defective sample, and revised on 2/15/15. Speaker company RBH has expanded their headphone lineup with new Bluetooth in-ears, the EP-SB. Lightweight and sweat resistant, RBH want the EP-SB to be your go-to headphones for on-the-go and at the gym. I got my hands on one of the first pairs available (literally!), and put them through their paces. How did they hold up? Lace up your sneaks and meet me after the jump.
