Poly Blackwire C3225 Stereo 3.5mm Headset

The Poly 7S4M7AA is a stereo headset from the Blackwire C3225 line that delivers clear conversations and rich media through a familiar 3.5 mm connection. Slip the plug into a laptop for a video call, a tablet for an online class, or a phone for streaming music, and the headset is ready without drivers or complicated setup.

Audio performance is handled by a closed-back design that houses 28 mm drivers. Dynamic EQ senses whether you are on a call or listening to music and adjusts the sound profile automatically, so voices stay crisp and playlists keep their detail. A boom microphone with noise-canceling technology focuses on your voice and filters out nearby chatter, making it a practical choice for open offices, shared workspaces, or busy home environments.

Comfort was clearly a priority in the design. The headband is made from a lightweight metal that adds durability without extra weight, and the ear cushions use a soft leatherette material that remains comfortable during long meetings. When the day is done, both earcups fold flat, so the headset slips easily into a bag or desk drawer.

The attached cable measures about 7.45 ft, giving you room to stand, stretch, or reach for a document while you stay on the line. Built-in hearing protection limits sudden sounds above 118 dB, an important safeguard for daily, extended use.

Whether you support customers from a contact center, join back-to-back video conferences from a home office, or need a reliable headset for hybrid classroom learning, the Poly 7S4M7AA offers a straightforward, high-quality solution that keeps pace with modern work and study.
