Fix 2: Reset the Headset
If pressing the power button doesn’t work, the next step is to reset the headset. Sometimes, headphones don’t charge due to minor software glitches. Resetting the headset can clear these glitches and improve its performance.
Follow the below steps to reset your Sony XM4 headphones:
- Press and hold the Power and CUSTOM buttons simultaneously while the headset is unplugged.
- Release the buttons once you see the LED indicator flashing in blue.
- The headphone will reset.
Fix 3: Use the Original Charging Cable
The Sony XM4 won’t charge if you are using some third-party cable. These cables are often not very good and create problems with your headphones. So, if your original cable went missing or was damaged, make sure you buy a new one and try charging with it. Your headphones should start charging again.
Furthermore, not properly plugging the charging cable can sometimes create a charging problem. To tackle this, make sure that the charging cable is always firmly connected to both ends.
Fix 4: Get Rid of Moisture in the Charging Port
Moisture is a big foe when it comes to your charging ports. Moisture can accumulate in the charging port of your Sony XM4 due to several reasons. It prevents electricity from passing through the charging port. And since there is no passage of electricity, your Sony XM4 won’t charge.
How do you fix this? Well, it’s simple. Dry the charging port on your Sony XM4 using a blower, or just leave it in a dry place for some time. Once the charging port is free of moisture, try charging it again, and the issue should be resolved.
Fix 5: Charge and Discharge the Headset
Did you keep your headphones discharged for a long time? Well, there’s some bad news for you. Keeping your headphones discharged for a long time, like six months or more, can damage your battery. This condition is referred to as “over-discharge.” But don’t worry; fixing this issue is pretty straightforward.
All you need to do is to charge your headphones for at least three to four hours before trying to use them again. The Song XM4 takes about three hours to fully charge. But since your battery is over-discharged, it is highly recommended to charge it for longer.
Once you have charged your headphones for at least three to four hours, check if you find any progress in the charging. If your headphones are charging, then the issue is resolved. If the issue persists, move down to the next solution.
Fix 6: Check for High Temperature
The temperature around the charging area can adversely affect the charging speed or functionality of your Sony XM4. Your headphones won’t charge if the ideal temperature is not found. What’s the ideal temperature? It’s between 5⁰C and 35⁰C. Make sure your room temperature is between these points. If it’s not, you may not be able to charge your headphones.
If you have the ideal room temperature, and your device still doesn’t charge, you should contact Sony support, as there seems to be something wrong with your headphones’ hardware.
Fix 7: Make Sure your Computer isn’t in Standby Mode
If you’re charging the headset with a computer, it won’t charge if the computer is in standby mode. In standby mode, computers don’t supply electricity. To fix this issue, make sure to charge your headphones when your computer is fully functional.
Fix 8: Replace the Battery
If none of the above fixes works, then the issue is likely with the battery of your device. The battery on electronic devices degrades over time, resulting in low efficiency and slower charging speeds. If you are experiencing low battery efficiency and slower charging speeds than usual on your Sony XM4, then it is a sign that you need to replace the battery.
To replace the battery, we highly recommend visiting a Sony service centre. They should be able to help you better.
To prevent your battery from degrading quickly, avoid exposure to extreme sunlight, moisture, or even high temperatures. Furthermore, avoid charging your headphones using third-party cables or any other cable that did not come in the box. Always use the original USB-C cable provided in the box of your Sony XM4. If you happen to lose it or it’s damaged, consider buying a new one from Sony.
If none of the solutions above has resolved your charging issue, it’s time to contact Sony support for assistance. The support team will be able to provide further troubleshooting steps and, if necessary, advise you on the best course of action.
You can contact Sony support through their website, email, or phone. Before contacting support, make sure you have your headset’s model number, serial number, and purchase details on hand.
