Pliant PHS-SB210E-U SmartBoom PRO Electret Dual-Ear Headset

The PHS-SB210E-U 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 ships unterminated, with bare cable leads so an integrator can fit whatever connector a non-standard belt pack or panel requires. 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.
