Overview

The Sennheiser UNP PC is a genuine OEM replacement cable for the EPOS/Sennheiser gaming headset lineup that uses a detachable mini-2.5mm connection at the ear cup. The cable terminates at the PC end in two standard 3.5mm stereo plugs — one for headphone output and one for microphone input — at a total length of 2 meters (6.5 ft). What makes this cable the correct buy for compatible headsets is its OEM provenance: manufactured to EPOS/Sennheiser's own specifications and shipped in original manufacturer packaging, it carries the same wiring pinout as the cable that shipped with your headset. This matters because analog audio cables for gaming headsets use manufacturer-specific pin assignments; an aftermarket cable with incorrect wiring can produce reversed channels, no microphone signal, or degraded audio.

The use case is straightforward: the detachable cable on gaming headsets is statistically one of the first components to fail, typically at the connector from repeated plug/unplug cycles or cable management stress. Replacing the cable extends the functional life of a headset that otherwise performs well, at a cost well below replacement. Compatibility spans fourteen EPOS and Sennheiser headset models, all sharing the mini-2.5mm connection standard — from the entry-level GSP300 to the higher-end GSP600 and H6PRO. For desktop users with discrete mic and headphone jacks, this cable is a direct drop-in replacement. Users on laptops or modern compact desktops with a single TRRS combo jack will need a separate splitter adapter to utilize both plugs.

Pros & Cons

👍 Pros

  • Genuine OEM EPOS/Sennheiser part in original manufacturer packaging — no wiring variance or quality step-down versus the factory cable.
  • 2M length gives desktop users meaningful reach without the drag of excessive slack.
  • Covers a wide range of the EPOS/Sennheiser gaming headset lineup with a single SKU — the same cable works across over a dozen models using the mini-2.5mm standard.
  • Detachable cable design means replacing a damaged cable restores full headset function at a fraction of headset replacement cost.

👎 Cons

  • Dual 3.5mm PC connectors require separate mic and headphone jacks — modern laptops and compact desktops with single combo jacks need a TRRS splitter not included in the box.
  • 2M may fall short for users with tower PCs on the far side of a large desk or floor-mounted cases at a distance from the chair.
  • The 2.5mm headset connector is specific to EPOS/Sennheiser's pinout — the cable is not interchangeable with other brands using 2.5mm ports without verifying wiring compatibility.

Frequently Asked Questions

It fits the mini-2.5mm socket found on the H3, H6PRO, GAME ONE, GAME ZERO, GSP300, GSP350, GSP500, GSP600, GSP602, GSP670, PC 373D, G4ME ONE, and G4ME ZERO. The key identifier is the mini-2.5mm port on the headset ear cup — if your headset has that connection, this cable is compatible.
Yes, for full functionality. One 3.5mm plug carries audio output (headphones) and the other carries microphone input. If your PC or audio interface only has a single 3.5mm combo jack, you'll need a TRRS splitter adapter, which is not included.
2M is adequate for most desktop configurations where the PC sits beside or below the desk. It won't reach a tower on the far side of a large studio desk without strain — in those cases a short USB extension or repositioning the tower may be needed.
This is a genuine EPOS/Sennheiser OEM cable in original manufacturer packaging — it is the original cable. Audio quality through an analog cable at this length is not measurably different from the factory-bundled unit.
The 2.5mm connector is a standard size, but wiring configurations (TRRS vs TRS, pin assignments) vary by manufacturer. This cable is wired for EPOS/Sennheiser's specific pinout. Using it with other brands may result in incorrect channel mapping or no microphone signal.
