## Summary description

WELL Mairdi MRD-QD009 is a headset/reducer adapter designed for telephone systems using RJ9 connectors compatible with Avaya phones. It provides a reliable physical interface between headsets and desk phones, enabling audio connection and quick plug-and-play setup. Ideal for call centers, offices, and customer support environments requiring standard RJ9 headset connectivity.

## Long description

WELL Mairdi MRD-QD009 is an adapter cable that provides a physical interface between headsets with a QD (Plantronics-style) quick-disconnect and desk telephones equipped with an RJ9 headset jack compatible with Avaya models. Designed for straightforward plug-and-play use, this adapter supports standard analog headset connectivity on Avaya 96xx and 16xx series phones and other telephone models that accept RJ9 headsets. The cable length of 0.8 m offers a compact, tidy connection suitable for desktop telephone setups in professional environments.
Advantages
The adapter ensures reliable electrical and mechanical connection between QD headsets and RJ9-equipped telephones, reducing connection failures and minimizing headset movement at the jack. Its compact 0.8 m cable keeps desktop areas uncluttered while providing sufficient reach for typical desk use. The use of a QD connector allows fast interchange of headsets without repeated wear on the phone jack, and the RJ9 interface maintains compatibility with Avaya 96xx and 16xx series phones and similar models.
Suitable for
Call centers and customer support desks using Avaya 96xx or 16xx series phones
Office workstations requiring a QD headset connection to an RJ9 telephone jack
Shared headset environments where quick-disconnect interchangeability is needed
Telephony setups that need a compact, low-profile adapter cable
Key specifications
Connector type (headset side): QD (Plantronics-style quick-disconnect)
Connector type (phone side): RJ9 compatible with Avaya telephone headsets
Cable length: 0.8 m
Compatibility: Avaya 96xx and 16xx series and other phones with RJ9 headset jack

How to use
Connect the QD plug of the adapter to the quick-disconnect connector on the headset until it locks. Insert the RJ9 plug into the headset jack on the Avaya desk phone. Verify the physical connection is secure and use the phone’s headset control (if present) to select the headset audio path. If audio is not immediately active, check phone settings and volume levels. To disconnect, release the QD latch and remove the headset without stressing the phone jack.
Usage recommendations
For reliable long-term performance, avoid sharp bends near connector ends and keep the cable free from heavy objects and repeated pinching. When used in multi-user environments, verify headset and phone compatibility before swapping connectors, and periodically inspect the QD latch and RJ9 plug for wear or debris.
