Hollyland Solidcom SE-4S Wireless Intercom, 4 Headsets

The Solidcom SE is Hollyland's lightweight full-duplex intercom for small crews, using self-contained single-ear headsets with no base station or beltpack to carry. It works over the 2.4 GHz band with auto frequency hopping that jumps to a clear channel when it meets interference, and dual-mic Environmental Noise Cancellation with a 70 dB signal-to-noise ratio keeps voices clean outdoors and on set. One headset serves as the master and the others connect to it, so a 4-person team can talk and listen at the same time.

The system holds a stable link up to 1,100 ft (350 m) and expands to a maximum of 5 headsets. The master headset runs about 10 hours and remote headsets about 12 hours, each on a detachable battery so a spare swaps in fast, and the headsets are built to shrug off wind and light water. This 4-headset kit ships with 4 single-ear headsets, 4 batteries, a charger, and a carrying case.
