Take Microsoft Teams calls with a stereo wired headset that connects directly to a USB-C computer and can also attach to a USB-A port through the included adapter. The Poly Blackwire 3325 combines two-ear audio with a boom microphone for users who need consistent call audio without charging, pairing, or managing a wireless connection. Its corded connection suits fixed desk positions, hoteling stations, and shared work areas where a headset must be ready when the user connects a computer. Microsoft Teams certification makes this version appropriate for Teams calling and meeting workflows. Inline call controls provide access to routine headset functions from the cable, reducing the need to switch windows during a conversation. The flexible boom microphone can be positioned close to the speaker, while the stereo headset layout keeps meeting audio in both ears for focused calls, training sessions, and media playback between conversations. HPP-8M3V5AA#ABA is the USB-C version supplied with a USB-C-to-USB-A adapter, allowing one headset package to support modern USB-C notebooks as well as systems with traditional USB-A ports. Within the Blackwire 3300 family, this configuration combines stereo listening, a Teams-certified control experience, and dual USB connection flexibility.
