HP Poly MDA100 QD PC-Phone Headset Switch – PC + Desk Phone Switch, USB to QD (8A7E1AA)

The Poly MDA100 QD PC-Phone Headset Switch (8A7E1AA) lets agents use a single QD headset across both a desk phone and a PC without swapping cables. One button switches the audio path between the phone and PC — critical for contact centers where agents handle both traditional PSTN calls on a desk phone and UC/softphone calls on a PC from the same workstation. It connects via USB to the PC and via QD to the headset, with an RJ9 or equivalent connection to the desk phone.

Key Features

• One Headset, Two Devices: Switch audio between desk phone and PC with a single button press — no cable swapping or headset re-plugging.
• USB to PC: Connects to PC via USB for softphone and UC platform audio.
• QD Headset Connection: Works with any Poly H-Series QD headset — no new headset purchase required.
• Streamlined Mixed-Mode Desk: Eliminates the cable management problem of dual-device agent workstations.
