Hollyland Solidcom C1 Offers More Options via Firmware Upgrade

October 31, 2022

Hollyland has reengineered its Solidcom C1—a full-duplex wireless intercom headset system with a free firmware upgrade for even richer communication experiences. The firmware upgrade makes possible up to an 8-person intercom headset system with 1 master headset and 7 remote headsets available at Amazon USAmazon UK, and Amazon AUS. Prior to the firmware package, to activate 8 or more headsets, a hub was needed in the system. 

The firmware upgrade must be performed on the master headset and each additional headset paired with the master. A PC is required to facilitate the firmware upgrade. For more information about how to perform the firmware upgrade, see the following additional notes. After the upgrade, you can further expand your Solidcom C1 package for more varying team sizes for communication.
