HP Poly Blackwire 3325 USB-C Headset

The HP Poly Blackwire 3325 is a wired stereo headset with a USB Type-C host interface and a 3.5 mm mini-phone connection. It features binaural on-ear coupling with an open design and leatherette ear cushions. A padded headband and 180-degree pivoting speakers support long-wearing comfort.

Suited for Microsoft Teams users needing simple

Workers who want a lightweight headset for daily calls will appreciate the omni-directional microphone and adjustable boom. The 7.05 ft cable gives desk mobility without wireless pairing steps. Buyers who require active noise cancellation or a closed-back design for noisy environments should look elsewhere.
