HP Poly D400 Headset Adapter
The HP Poly D400 Headset Adapter connects a compatible headset to a host device. It is aimed at office workers, remote employees and contact-centre staff who need a simple way to use their headset for calls and meetings.
Replaces older inline adapters
This adapter replaces earlier inline or proprietary connectors that may no longer fit modern ports. The jump is worth it when a headset lacks a native connection to the current workstation or laptop.
Single-headset connectivity
The adapter comfortably handles one headset for voice and multimedia audio. It runs out when a user needs simultaneous connections for multiple headsets or advanced audio routing not supported by this single-port design.
