Poly A10-12 S1/A H-Top Adapter Cable

The Poly 85S26AA is an adapter cable that lets you connect a Plantronics H-series headset directly to a desk phone with a dedicated headset port. By going straight from headset to phone, it removes the need for an external amplifier and keeps your workspace straightforward.

Installation is quick. Plug the cable into the phone, attach the headset, and start talking. There is no software to configure and no extra power source to manage, which means less downtime for users and fewer support calls for IT teams.

Once connected, the cable carries audio that is both clear and consistent. Every voice comes through accurately, so conversations remain professional whether you are on a sales floor, supporting customers in a contact center, or working from a spare bedroom at home.

The cable feels light, so it routes easily behind monitors or through desk grommets, yet the build quality stands up to daily bends and unplugs. Because it works across the full family of Plantronics H-series headsets, offices can standardize on one simple solution and keep spares on hand without worrying about model mismatches.

If you want a cleaner setup for your existing Plantronics headset or you are rolling out new stations across an entire team, the Poly 85S26AA provides a dependable path to clear calls and simpler desks.
