Sennheiser MOMENTUM True Wireless 4: check one-sided silence
Try the documented restart without clearing pairings.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Original matched MTW4 earbuds. This is a general non-destructive restart, not a diagnosed repair for a silent side. Stop using an earbud that makes loud unusual noise or appears damaged and seek support.
Connection scope: Bluetooth. Symptom: Sound plays from only one side.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
What owners have reported
These are public, self-reported experiences. They help explain the order of checks and the limits of a guide. They are not controlled tests, proof of a cause, a success rate or a substitute for the manufacturer instructions above.
User-reported MOMENTUM True Wireless 4 left earbud no longer plays audio
User-reported: the affected earbud retained controls but stopped producing audio; replies include another explicit MTW4 account.
How this informs the checks: Separate functioning controls from audible playback, offer only the documented restart, and retain a support exit for persistent silence.
Limits: No inspection establishes a failed component or a common cause. Reply counts and anecdotes do not establish a failure rate.
