Eartec 5 Pack 3.7V Rechargeable Lithium Ion Battery for HUB Ultralite Headset

Description

Since the UltraLITE headphones feature a self-contained, "All-in-one" design, all electronics, including the battery, are installed in the plastics of the headphones. The batteries are lightweight and about the size of a match book. They charge in about 3 hours, run for 6 hours and can be changed in seconds. Since they are lithium-ion, the batteries do not have to be "drained" after each use and will never develop a memory.
