Fortunately, some fixes are quick ones.
Here is a pair of Logitech G935 gaming headphones that you can't hear anything through, due to some problem with the ON/OFF switch. Their sound quality had steadily degraded and the switch had to be jiggled around to get any sort of reasonable output; but eventually even that didn't work. The ear pads are also shot, as all the pleather has peeled away from the fabric covering the foam cushions.

A very brief web search demonstrated that this is a common problem with these headphones (and with Logitech headphones in general); with the contacts in the switch becoming dirty or oxidised over time. Gemini gave a few options for a fix. The first, toggling it on and off rapidly and wiggling the switch around to get a decent signal, I had already exhausted.
After a quick look at a couple of YouTube videos on disassembling the headphones [1/2] it looked like trying to get contact cleaner into the switch from outside would be challenging. So I decided to open up the headphones and strip down the switch as per the excellent YT vids.

Six screws round the left hand side speaker opened the case, with a further two holding the button fascia and the PCB into place. All removed with a jeweller's screwdriver.

Once unsecured I removed the flexible flat cable to separate the left speaker assembly from the headphones for ease of access.

If you squint you can see that contacts are not very bright. To clean them I applied a squirt of WD-40 Contact Cleaner and a bit of vigorous brushing with a small brush (yellow TePe size 4, 0.7mm interdental brush) that happened to fit the recess with the contacts in it perfectly. Also by happenstance it had been stored next to a cotton wool bud and the cotton wool had entangled itself with the brushes' bristles, which only helped to clean up the contacts.
A word of caution about the contacts on the top half of the switch. Clean these carefully, they aren't securely attached and are really thin (and therefore easily lost). Although not too difficult to reseat.

After cleaning the contacts were visibly brighter and on reassembly everything was back to 100% performance.
The next task was to source some replacements for the ear cushions that had perished. I started with the Logitech Support Pages, which stated "There are no Spare Parts available for this Product". More superb customer service from a US company...
I did find genuine spares on iFixit at £23.00 plus another £8.40 shipping for the princely sum of £31.40. As the headset is only worth £30-40 now, this is egregiously expensive. So next I tried Amazon, which Gemini recommended, 57% cheaper at £12-15 (inc. P&P) and some had a replacement headband included. Then eBay, about £8 (75% cheaper) again with headband and finally onto AliExpress, my new favourite parts shop, £3.57 (inc. P&P from China!) or 89% cheaper than the official Logitech parts. At this price I could buy ten pairs for each genuine part. So, even if they don't last the four years that I had the originals for, if they manage more than 5 months they are more cost effective than the Logitech parts. Yes, I know that the quality may not be as good, but I am not a high end user and that doesn’t excuse Logitech from trying to rook their users. However, let's see what they look like when they arrive.
So I waited for the slow boat from China.
Some time later…

| Replacement G935 ear cushions |
What arrived from Dongguan Qingyuan Underwear Accessories Co. Ltd. was a close-ish copy of the originals. As you can see, they were not quite the same shape and the stitching was not up to the same quality, though what can you expect for £3.57 shipped from China? I couldn't really feel much difference in the quality of the pleather.
Fitting was straightforward for the ear cushions. I simply stripped off the old ones and spent a few minutes cleaning up the exposed surfaces, and then the rest of the headphones as I had made clean spots. The new cushions slipped on fairly easily and looked and felt OK.

Unlike the ear cushions, the headbands were glued down and had to be peeled off. The black support attached to the back of the head band (see below) came away at the same time and was a little tricky to remove. But once done I placed it back into position at the crown of the

The new headbands had a self-adhesive backing and were simply pressed into place. Time will tell how they stand up to wear and tear.
JOB DONE
Time: About 45 mins
