Shokz OpenComm2 2025 Upgrade - Bone Conduction Bluetooth Headset, No USB Dongle

Shokz OpenComm2 2025 Upgrade (C120-AN-BK) - Bone Conduction Bluetooth Headset, No Dongle

The OpenComm2 2025 Upgrade is a Shokz bone conduction stereo Bluetooth headset with an adjustable boom microphone. It sits in front of the ears rather than on or in them, so you can hear what is around you. This part number, C120-AN-BK, is supplied without a USB dongle: Shokz lists the box as the headset, a USB-C charging cable and a hard carrying case. The UC versions with the Loop120 USB-A or USB-C adapter are C120-AA-BK and C120-AC-BK.

What the OpenComm2 is for

It suits calls on a mobile phone or a Bluetooth-equipped computer, for people who work on the move or want to keep their ears open while on calls. For PC use with a USB adapter, see the OpenComm2 UC versions. Browse more headsets or the Shokz range.
