Compatibility And Setup Checks

Verify that your computer, mobile phone and desk phone each support the headset's wireless connection method before purchasing. The package includes a rechargeable 140 mAh lithium-polymer battery that can be swapped during an active call for continuous use. Ensure your work environment allows a clear line of sight for the stated 328 ft (100 m) roaming distance. No specific Bluetooth version or USB standard is detailed in the specifications.

Battery Life And Thermal Comfort

Talk time reaches up to 5 hours on a single charge, with the swappable battery design enabling unlimited operation when a spare is kept ready.
