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.
Separate charging faults from battery deterioration.
Signs to investigate
- Short runtime
- Cannot retain charge
Prepare your bench
- Known-good supported USB cable and charging source
Diagnose, isolate, then service
- 01
Compare charging with another known-good cable and supported USB source.
- 02
A technician should inspect the right-earcup battery assembly and temperature-sensor arrangement.
- 03
Preserve the original connector, polarity and sensor provisions; never bypass protection circuitry.
Do not handle a swollen, leaking or damaged pack.
Normal charging and unplugged runtime, with no abnormal heat.
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.
