HP Poly RJ-45 to QD Headset Cable – H-Series to RJ-45 Headset Port (784S2AA)

The Poly RJ-45 to QD Headset Cable (784S2AA) connects Poly H-Series Quick-Disconnect headsets to desk phones or devices that provide headset audio through an RJ-45 port rather than the more common RJ9 or 3.5mm ports. Some enterprise phone systems and IP phones route headset audio through an RJ-45 headset jack — this cable bridges that connection to the standard Poly H-Series QD headset ecosystem without requiring a separate adapter box.

Key Features

• RJ-45 Headset Port Connection: For phones and systems that provide headset audio through an RJ-45 port — connects directly without an additional adapter.
• Quick-Disconnect End: Allows instant headset removal for walkaway convenience without ending the active call.
• H-Series Compatible: Works with the full Poly H-Series QD headset range.
