Electronic Partners did a fantastic job repairing my headphones! As you can see from the before-and-after pictures, they’ve brought them back to life. … More I love how they look now—I can wear them out with confidence. The repair process was quick, and they even fixed my volume button, which was a nice bonus. Highly recommend their service! 😊🎧 -
Excellent service and kept informed throughout the process. Was initially concerned as I thought I was dealing with a local company where I could have … More dropped my DVD player in for repair only then to find out I had to post it via the Royal Mail service. All postal requirements were sent over and in the event the service was quick and painless and given notification of its safe arrival. As the DVD player sound surround system was around 20yrs old I was surprised that Electronic Partners were able to undertake a repair and give us many more years service of our system meaning no wastage of all the other perfectly good parts such as the speakers. EP also met my need in delaying the return postage until a time that I was able to be at home to receive the DVD player. Would definitely recommend EP and would use again where one can repair and reuse perfectly good equipment rather than unnecessarily throw it away. Many thanks EP. -
Brilliant service! Communication was top notch, cost was competitive and I would definitely use again! So pleased to have my ancient Sony system working … More again!
What this repair page covers
This page focuses on WH-1000XM4 battery faults within our headphone repair service category. It is designed to help customers quickly judge whether their symptoms match a repairable pattern and whether it makes sense to move forward to diagnosis.
Symptoms customers commonly report
- Haven’t used them in a very long time and now they won’t charge. It goes red for a minute but then just stops charging. It will turn on for a split second and say battery needs charging and that’s it.
- I've had headphones for a while now and just recently they've stopped playing audio through the right ear, as well as staying on 10% battery and running out of charge very quickly.
- I cannot get they to take charge. Using a certain method I can get a light on to show it is plugged in but left overnight it stayed at low battery.
- Only charges when I switch on the headphones. Now that the battery is fully dead (won't switch on), I cannot charge it.
- I used a laptop charger to charge headphones an now the battery is damaged and won’t charge no more with any charger.
- Item was bought untested but brand new item is not charging or turning on when connected to power.
Why this fault matters
Battery is a meaningful commercial repair intent because customers usually search for it when they already suspect the fault and want to know whether repair is realistic. That makes a focused page more useful than a generic service summary.
Related models appearing in the same repair pattern include WH-1000XM4.
What usually causes this problem
Cause analysis depends on the specific symptoms, device condition, and whether the visible fault appears isolated or connected to wider damage.
What the diagnostic process usually needs to confirm
The diagnostic process usually needs to separate the visible fault from any related internal issues before repair viability can be judged properly.
When repair is usually worthwhile
Good Repair Candidate
This kind of fault is usually worth exploring when it is isolated, the device still has strong replacement value, and the rest of the hardware remains commercially viable.
Cases That Need Caution
Repair can become less attractive when the visible fault is only one symptom of wider liquid, board-level, or structural damage that changes the economics of the job.
Next step if this matches your fault
If your device symptoms are close to the pattern described above, the best next step is to request an estimate through the Headphone Repair route. That keeps the enquiry aligned to the correct workshop flow and gives the team the device and fault detail needed for diagnosis.
