Pliant PHS-SB210E-4F SmartBoom PRO Electret Dual-Ear Headset

The PHS-SB210E-4F is the electret version of Pliant's SmartBoom PRO dual-ear intercom headset, built on a cardioid electret microphone tuned to reject stage wash and monitor spill so a call cuts through a loud room. Closed-back circumaural earcups seal over both ears for stronger isolation, and the SmartBoom boom mutes with a flip: up is off, down is live.

This version terminates in a 4-pin XLR female connector, matched to CrewCom radio packs that carry a male headset jack. The ear cushions, headband pad, and windscreen are all user-replaceable, and the rubberized matte-black shell stays non-reflective under stage and studio lighting.
