The Hollyland Solidcom SE-Remote Headset (SOLSE-HS02) is an additional remote headset for the Solidcom SE full-duplex wireless intercom, used to expand an existing system or replace a unit. Solidcom SE needs no base station: a master headset hosts the network and remote headsets like this one connect to it, with up to five headsets in total. Teams in video production, live events, churches, sport coaching and refereeing use it for hands-free, simultaneous conversation. It operates in the 2.4 GHz band with automatic frequency hopping and gives up to 350 m (1,100 ft) line-of-sight range. Dual-microphone environmental noise cancellation cuts more than 20 dB of background noise, and push-to-talk plus a movable boom make it easy to control. The 770 mAh battery is swappable, with Hollyland quoting about 12 hours per charge on a remote headset and under three hours to recharge. Weight is about 185 g with battery. A Solidcom SE master headset is required and is not included.
