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.
Check the acoustic path before internal driver work.
Signs to investigate
- One ear silent

Diagnose, isolate, then service
- 01
Test a second audio source and wired audio at low volume.
- 02
Inspect cushion fit and visible debris before opening.
- 03
Internal driver work requires a technician: the earcup halves are wired together, and driver connections must be preserved.
Do not touch the diaphragm or power an open assembly near your ears.
Balanced, clear audio at a moderate level.
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.
