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.

Questions about this item

What connector does the HP Poly D400 Headset Adapter need on the headset side?

The adapter is built for a headset connection, so it plugs directly into the headset's own port without an extra cable.

How do you install the HP Poly D400 Headset Adapter, and what step do people skip?

Insert the adapter into the headset port until it clicks, then connect the other end to the host device; the step often missed is confirming the click that locks it in place.

What part of the HP Poly D400 Headset Adapter will need replacement first?

The adapter has no moving parts or batteries, so under normal use it does not require scheduled maintenance or component replacement.
