CKMOVA Wicom E S7 Full-Duplex Wireless Intercom System
The CKMOVA Wicom E S7 is the largest single-ear Wicom E kit, with seven headsets: one master and six remotes, all full-duplex on one channel with no push-to-talk. It uses the license-free 1.9GHz DECT band with DECT 6.0 encryption to stay clear of Wi-Fi and camera RF, reaching up to 1312 ft (400 m) from the master to a remote and up to 2624 ft (800 m) remote to remote. Dual-microphone ENC keeps each voice clean over set noise.
The open single-ear design keeps one ear on the room, which suits a full camera, grip, lighting, and floor team working live. Seven headsets covers most productions on its own, and the system still scales: each master handles up to eight remotes, and masters chain through their 3.5mm TRS ports to build up to 18 remote headsets. Each headset charges over USB Type-C in about two hours, with up to 10 hours of runtime per remote. The kit ships with one master and six remote headsets, batteries, USB-C charging cables, and a carrying case.
