Coby Metal Folding Bluetooth Headphones...

Premium Wireless Audio Portability: Coby delivers another high-fidelity, wireless, personal audio solution that includes a super-comfort, metal profile that folds for supreme portability and convenience.
Bluetooth Enabled Wireless Playback: Enjoy up to 10 hours of unencumbered listening, wirelessly paired to your Bluetooth device at up to 33ft away! Volume and track controls are conveniently positioned on the headset. A rechargeable, lithium-ion battery makes it all imaginable with only 2 hours of charge time.
High-Fidelity Sound: Coby CHBT808 headphones match their state-of-the-art design with brilliant, full-spectrum sonic excellence. Featuring 40mm diameter speaker drivers, both sides deliver the very best blend of full bass reproduction to high end stereo sound. Not too large, but far from small. Sensitivity: 100db + 3db
Premium Comfort by Design: If you’re searching for substantial, over-ear audio that doesn’t weigh you down, Coby has the solution in the CHBT808’s. An adjustable, padded headband secures the device comfortably whilst the foam-cushioned ear pads create a pillow-soft seal for your ears.
Light and Portable: Folding, or collapsible headphones was the domain of flimsier models that lacked premium features. Coby has redefined portable audio with the wireless CHBT808, outfitting it with a folding, swivel-joint design that allows you to enjoy top quality audio, anywhere!
Exclusive Features: 3.5mm Aux in port for wired listening. One-touch call answering. TF Card and USB ports.
