Pliant PHS-SB110-4F Headset
SmartBoom PRO is Pliant's line of professional communications headsets for wireless and wired intercom. Every model uses a closed-back circumaural earcup for real acoustic isolation, a comfort-fit adjustable headband, and a dynamic noise-cancelling hypercardioid boom mic tuned for voice. The defining feature is the SmartBoom flip-up boom: raising the mic mutes it, so an operator can drop off a busy line without hunting for a switch. Ear cushions, headband pad, windscreen, and the cable itself are all field-replaceable, so a working headset stays in service instead of heading to a drawer.
The line comes in single-ear (PHS-SB110) and dual-ear (PHS-SB210) versions, each with a 5 foot field-replaceable cable in a choice of terminations: 4-pin XLR female, 4-pin XLR male, 5-pin XLR male, 6-pin mini XLR female, or unterminated for a custom fit. That connector spread lets one headset family match single- and dual-channel belt packs across the intercom market. Each headset ships with an ear sock, magnetic cable clip, windscreen, cloth storage bag, and operating manual.
