Designed for use in enterprise deployments, the Blackwire 3320 Stereo USB-C Headset from Poly is a noise-canceling headset that features a flexible boom microphone and a USB-C interface for connecting to most Macs and Windows PCs. The stereo design features leatherette-encased, on-ear speakers featuring hearing protection to guard against sounds above 118 dBA. Additionally, the Blackwire 3320 comes equipped with inline controls that let you answer, ignore, end, hold, redial, and mute calls as well as adjust the volume. The inline controls can also be used to control music and other multimedia applications. When you're finished with your call or multimedia application, the Blackwire 3320 folds flat for portability.
