Does Califone have wireless headphones that do not use size AA batteries and are instead rechargeable?
Yes. The CLS wireless headphones use a proprietary rechargeable battery. To charge the batteries, simply connect the CLS700AC charging adapter into the CLS-CH8 charging lead and then connect the headphones to the charging lead using the cords it comes with. Turn OFF the headphone prior to charging. We recommend to always charging when not in use to ensure battery life. The charge time is approximately 8 hours.
