Check the symptom first: restart for brief audio dropouts, reset for pairing failures, and full initialization only after both fail, before you press the case button. Use the wrong step and you can clear pairings, leave the buds offline, or push yourself back into re-pairing. This article maps Sony models, then gives the exact restart, reset, and initialization steps.
What this reset problem usually means
When Sony earbuds will not power on, ignore touch or buttons, or refuse to pair, the fix is not always the same. The fastest first move is to decide between a restart, a soft reset, or a full initialization.
Quick symptom check
Use restart when audio briefly glitches or one side drops out. Use reset when the earbuds cannot be turned on or controlled. Use initialization only after the basic reset fails, because Sony may treat it as the deeper wipe step for the product line.
Say your left bud stops responding after a case battery drain. That is a reset problem only if the buds still charge and the case can trigger the procedure. If the case has no power, charging comes first.
Why Sony uses different reset names
Sony support uses model-specific wording such as reset, initialization, or factory reset. Some models keep pairing information after a reset. Others need re-pairing. That naming difference is why one generic answer often misses the mark.

Which Sony reset do you need?
Pick the least aggressive fix that fits the symptom. A restart only refreshes a live connection. A soft reset is the first repair step for earbuds that stopped responding. Initialization, sometimes called factory reset, is the deeper step when the basic reset does not solve it.
Soft reset: first step for unresponsive earbuds
A soft reset is the right move when the earbuds cannot be turned on or controlled, but the case and charging system still work. Sony says to place the earbuds in the charging case before starting. Keep the lid open while you do it.
Initialization or factory reset: the next step
If the earbuds still do not work properly after the reset, Sony says to initialize them. That restores factory settings for the model. On search pages, this is often confused with Microsoft’s “Reset this PC,” which offers Keep my files and Remove everything; that Windows terminology is unrelated here.
How to tell whether pairing data will be kept
Some Sony models keep pairing information and other settings after a reset. Others do not. The model family matters more than the headline term. If pairing survives, Bluetooth may reconnect faster. If it does not, you will need to remove the earbuds from Bluetooth and pair them again.
Likely causes, ranked
Most often, the reset fails because the case battery is too low, the buds are not seated correctly, or the reset button was not engaged the right way. Less often, corrupted Bluetooth data or a deeper hardware fault is the real issue.
1) The case battery is dead or too low to trigger the reset
- Charge the case with the earbuds inside.
- Open the lid and confirm the case shows a charge indication.
- Retry the reset only after the case has enough power to run the sequence.
2) Charging contacts are dirty or the earbuds are not seated correctly
- Remove both earbuds from the case.
- Check that each bud sits fully in its charging bay.
- Clean the charging contacts gently with a dry, lint-free swab.
- Reseat the earbuds and repeat the reset attempt.
3) The lid sensor or case button is not being engaged the right way
- Open the charging case lid and leave it open.
- Place both earbuds in the case before pressing anything.
- Find the reset button on the back of the charging case, if your model has one.
- Hold it for at least 20 seconds.
4) Firmware or Bluetooth pairing data is corrupted
- On your phone or computer, open Bluetooth settings.
- Remove the Sony earbuds from the saved device list.
- Restart Bluetooth on the phone, tablet, or laptop.
- Pair the earbuds again after the reset finishes.
How to reset Sony wireless earbuds
Put both earbuds in the charging case first, keep the lid open, then press the case reset button on the back if your model has one. Hold it for at least 20 seconds. An orange indicator light should start blinking after about 15 seconds, then turn off when the reset finishes.
Reset steps for case-button Sony earbuds
- Place both earbuds in the charging case.
- Keep the lid open.
- Press and hold the reset button on the back of the charging case.
- Keep holding for at least 20 seconds.
- Watch for the orange indicator light to blink after about 15 seconds.
- Release the button when the indicator turns off.
What the light means
An orange indicator is often used as a confirmation sign during the reset. If it never lights, the case may not have enough battery, or the button may not be engaging. Sony also warns that releasing the button too early can initialize the earbuds instead.
Suppose the buds are in the case, the lid is open, and nothing happens after 20 seconds. That usually points to power, seating, or button contact issues rather than a bad Bluetooth pairing problem.
How to reset Sony wireless headphones or a wireless stereo headset
Match your model family before you start, because Sony uses different reset methods across earbuds and wireless stereo headsets. Some headsets use a power or function-button sequence instead of a charging case button, and some newer earbuds may rely on touch controls plus a separate initialization path.
Use the button layout Sony assigns to that model
For WH and similar headset lines, the reset method often uses the power button, custom button, or function button rather than a case button. The exact sequence is model-specific, so check the product family first and do not force the earbud-case method onto a headset.
When the headset uses touch controls
If the model uses touch controls, a charge-case reset may not apply. Look for Sony’s initialization or reset instructions for that family, then follow the timing and button combination listed for that exact headset.
| Model family | Typical reset control | Indicator behavior | Does pairing data stay? |
|---|---|---|---|
| WF-series true wireless earbuds | Charging case button on the back | Orange light blinks after about 15 seconds, then turns off | Often preserved after reset, model-dependent |
| LinkBuds-style earbuds | Charging case button or model-specific touch sequence | Indicator confirms the reset, then powers down | Model-dependent |
| WH-CH520 wireless headphones | Power and function-button reset sequence | Model guide specifies LED flash or shutdown pattern | Varies by reset type |
| WH-CH500 wireless headphones | Button sequence on the headset body | LED behavior depends on the reset step used | Varies by reset type |
| Wireless stereo headset families | Model-specific buttons or touch controls | Indicator confirms reset or initialization completion | Depends on Sony’s reset step |
What to do if the reset worked but pairing still fails
If the reset completes but Bluetooth will not reconnect, the problem is usually saved pairing data on the phone, tablet, or laptop. Remove the earbuds from Bluetooth, then pair them again. If another device still has them saved, that device may keep grabbing the connection.
Re-pair the earbuds or headset
- Open Bluetooth settings on the device you want to use.
- Select the Sony earbuds or headset from the saved devices list.
- Choose Forget, Remove, or Unpair.
- Put the Sony device back into pairing mode.
- Select it again from the Bluetooth list.
Check for a second saved connection
Look on nearby devices such as a laptop, tablet, or second phone. A stale connection can block a clean re-pair. Delete the Sony device from every place it was saved, then try pairing from one device only.
A common first-timer mistake is pairing from a phone while a laptop three feet away still owns the old Bluetooth record. The result is a pair attempt that looks successful for a moment, then fails or drops audio.
Still not working?
If the reset path fails, charge the case fully, clean the contacts again, and repeat the correct model-specific procedure. If that still does not help, initialize the earbuds or headset using Sony’s deeper reset step for that product family. If Bluetooth still fails after that, hardware service may be the next move.
If that didn't work, try this next
- Charge the case until it has a full battery.
- Reseat both earbuds and repeat the reset with the lid open.
- Run the model’s firmware update if Sony support provides one.
- Try initialization if the basic reset did not fix the issue.
- Contact Sony support or a service center if the case button stays unresponsive or the buds never charge.
Prevention
Keep the charging contacts clean and avoid storing the earbuds with a nearly dead case battery. That lowers the chance that a reset will fail because the case cannot complete the sequence.
