Talk Time

With a single full charge, the headset will provide up to six hours of continual talk time. Talk time will be reduced when operating in wideband mode and/or if the headset is used consistently at a long distance from the base. You can replace the battery mid-call, without losing the call, as long as a charged battery is reattached within 5 minutes. This allows for unlimited talk time.
