This is the PULSE 3D headset, not PULSE Elite CFI-ZWH2, the older Pulse Elite Edition or third-party headsets. Internal cards provide assessment routes where the available source is a teardown rather than a repair manual.

PRACTICAL REPAIR NOTES

Unclip the cushion frame and inspect the model label underneath.

Signs to investigate

  • Worn cushion surface
  • Loose cushion frame

Prepare your bench

  • Soft cloth

Component procedure

  1. 01

    Switch off and disconnect the headset. Hold the earcup steady.

  2. 02

    Grip the cushion’s frame and pull it away evenly, keeping force off the fabric.

  3. 03

    Inspect the mounting frame. Align the compatible cushion with the inner frame and press until its clips engage.

STOP POINT

Stop if the frame starts to crack. PULSE Elite cushions are a different assembly.

BEFORE YOU CALL IT DONE

The frame is secure around the entire earcup and the cushion forms an even seal.

Restore all covers, shielding and cable routing before powered tests. Keep each screw in its original position. If fit or resistance changes, reopen and inspect rather than tightening harder.
