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!

They provided a first class service in repairing our Bose CD player at a reasonable price. Everything went well in a very timely fashion- collection, repair … More estimate, repair itself and delivery back. CD player back home and playing like new. Service at its best. If I could give them 6 stars I would!
What this repair page covers
This page focuses on WH-1000XM4 hinge failures, including cracked swivel points, broken arms, and structural damage that affects how the headphones open, close, or sit securely. If your headset is showing that kind of fault, this page should help you judge whether the damage still looks commercially repairable.
Symptoms customers commonly report
For headphone repair, hinge faults usually appear as cracked swivel points, broken yokes, or housings that separate under normal opening and closing.
- The left joint between the ear cup and headband has broken such that a small piece of plastic and a small metal part came off, and now the left ear cup hangs lose and will turn all of the way around (which it is not…
- Not sure how the fault happened I simply had it secured at a relatively safe space and I look towards it and the ear muff is twisted incorrectly and I try to twist it back and it detaches with the wire still intact.
- The hinge isn't the only problem, but there is quite a bit of cosmetic damage in that area, the plastic hangar on the left side is snapped (shown in picture) and there is also an issue with the battery drain.
- As I was taking off headphones, the left hinge broke. The U-shaped metal clip that fell out is intact, but a small black plastic piece also came loose. As a result, the left ear cup now moves quite freely.
- The thing that goes over ear on the right, the hinge on it is broken so it doesn’t stay in place. I think something from the inside came out because there’s shards of black stuff when i woke ip.
- One side of the headphones sound is very muffled, sort of sounds like one ear is underwater. Also when I turn the hinges to put them back in the case one ear started making a screeching sound.
Why this fault matters
Hinge repair is a strong commercial intent because customers normally already know the physical failure point and want to judge whether the headset is still worth repairing. On premium models, hinge faults are often much more viable than full replacement.
Related models appearing in the same repair pattern include WH-1000XM4.
What usually causes this problem
Stress At The Swivel Point
Premium headphones often fail where the earcup arm repeatedly flexes under normal opening, closing, and carrying.
Fatigue Around The Housing
Cracking can spread into the surrounding shell or yoke area, which changes whether the repair is a simple structural job or a broader rebuild.
What the diagnostic process usually needs to confirm
The diagnostic process usually checks whether the break is isolated to the hinge or spreading into the headband and earcup housing.
It also matters whether the structural fault has created cable strain, driver instability, or cosmetic damage beyond the obvious hinge failure.
When repair is usually worthwhile
Good Repair Candidate
Premium headphones are usually good candidates for hinge repair because the rest of the electronics and acoustics may still be working well, which makes structural repair more sensible than replacing the full unit.
Cases That Need Caution
Repair becomes less attractive when hinge damage is combined with liquid exposure, battery failure, or heavier frame damage spreading beyond the original break point.
