The headset rating label is beneath the right ear cushion. Hold the cushion frame when removing it; do not pull only on the fabric.
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.
Localise a port fault before board-level repair.
Signs to investigate
- Loose USB-C port
- Intermittent wired sound
Prepare your bench
- Good lighting
- Known-good audio and USB cables
Diagnose, isolate, then service
- 01
Switch off; inspect the ports and test alternate cables.
- 02
The left earcup contains the main electronics. Port damage needs board-level assessment, not forceful cable movement.
- 03
Have a technician inspect joints and pads, then test charging, wired audio and wireless audio separately.
Do not probe inside a powered port.
All connection modes work without pressure on the plug.
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.
