CKMOVA Wicom E S5 Full-Duplex Wireless Intercom System

The CKMOVA Wicom E S5 is a full-duplex wireless intercom kit with five single-ear headsets: one master and four remotes, all open on the same channel with no push-to-talk. It runs on the license-free 1.9GHz DECT band with DECT 6.0 encryption, which sidesteps Wi-Fi and camera-RF traffic and holds up to 1312 ft (400 m) between the master and a remote, and up to 2624 ft (800 m) remote to remote. Dual-microphone ENC on each headset cuts background noise for clear talkback on a busy set.

The single-ear cups leave one ear open to the room, a good fit for camera, grip, lighting, and floor crew. Five headsets is the shipped configuration, not the limit: each master supports up to eight remotes, and masters link through their 3.5mm TRS ports to reach up to 18 remote headsets total. Every headset charges over USB Type-C in about two hours, and a remote runs up to 10 hours per charge. The kit includes one master and four remote headsets, batteries, USB-C charging cables, and a carrying case.
