CKMOVA Wicom E S3 Full-Duplex Wireless Intercom System

The CKMOVA Wicom E S3 is a full-duplex wireless intercom kit with three single-ear headsets: one master and two remotes, all speaking and listening at once with no push-to-talk button. It works on the license-free 1.9GHz DECT band with DECT 6.0 encryption, which stays clear of Wi-Fi and camera RF and reaches 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 voices clean over set noise.

The open single-ear design lets an operator keep one ear on the room, which suits camera, grip, and floor roles. A three-headset kit is a starting point, not a ceiling: each master handles up to eight remotes, and masters chain through their 3.5mm TRS ports to build a network of up to 18 remote headsets. Each headset charges over USB Type-C in about two hours and a remote runs up to 10 hours per charge. The kit ships with one master and two remote headsets, batteries, USB-C charging cables, and a carrying case.
