ByTech BYAUBO101BK Bluetooth Headphones - Black

Flimsey quality. Battery died completely. Bought a replacement battery. Tore up the headphones trying to replace dead battery.

Second pair broke the same as the first, both had the plastic hinge at the speaker break off

I picked these up from Office Depot for $9, and discovered they hide a secret....The battery is a generic 300 mah Nokia style BL-5B!! The non-control side panel unclips to reveal a slot for a Nokia battery. I'm ordering a higher capacity one now.
