Geemarc CL7100/CL7150 Wireless TV Listener Additional Headset
It comes with a built-in rechargeable battery and two pairs of ear buds. A separate charger is not included as the main charger provided with the CL7100/CL7150 charges two headsets at once. Its also worth noting that up to four headsets can be used at the same time with the CL7100 or CL7150.
The extra headset has exactly the same functions as the one supplied with the base unit to allow volume and tone to be set at your own preferred level. No pairing needs to be done to the base unit, just place the headset on the charging base and after the required charging time (3 hours) it will be ready to use.
