Poly Blackwire 3215 Monaural USB-A Headset (Bulk)

The Poly Blackwire 3215 extends the Blackwire 3200 Series' monaural design with 3.5mm connectivity alongside its USB-A connection, so the same headset can move between a PC and a mobile phone or tablet. It shares the series' noise-canceling omnidirectional microphone and Dynamic EQ, which optimizes voice quality on calls and automatically adjusts for multimedia listening.

A lightweight metal headband and foam ear cushions keep the monaural design comfortable for one-ear wear, with inline controls for call answer/end/hold, redial, mute and volume. This bulk-packaged variant is sold in multi-unit master cartons for enterprise fleet rollouts, and SoundGuard acoustic protection limits sound exposure to below 118 dBA.
