Replace Torn Earpads on Headphones

I've replaced the ear pads on my Acme BH316 headphones.

The ear pads told to be not replaceable, and no spare parts are offered for this model, so I've attempted to circumvent it. (Based on info collected from my colleagues, so credits go for them, too!)

Supplies

1. A pair of earpads from eBay/AliExpress or other source: https://www.aliexpress.com/item/1005005476225751.html (85mm x 105mm fits perfectly on the Acme BH316)

Tools

1. A small flatblade screwdriver
2. A small Phillips screwdriver or similar blunt tool
3. Vacuum cleaner or compressed air

I could simply pull&peel the majority of the pads easily by hand. This way the 6 small sunken joints are much more accessible and the adapter ring with the rest of the pad can be removed easily.

Just stick a flat screwdriver to some of the 6 joints, lightly press and bend and the joints release.

Remove the remnants of the pad from the ring.

Since small microplastic "dirt" coming from the degrading pads cover the desk and the headphones, I vacuumed it carefully.

Fit the ring into the "pocket" on the back side of the pad. Make sure that the joint protrusions faces outward.

Halfway it goes easily. For the other half you may use a blunt tool (e.g. a small Phillips screwdriver), so the second half goes in smoothly.

Take care that the "backfoil" of the pad must not cover the protrusions.

Align the pad with the ring to the headphones. Firmly press it together on all 6 spots. You need to hear the clicking sound 6 times.

Enjoy the headphone for many years.

According to my experiences with the first headphones, I've replaced the pads on this way, the spare parts are really good quality, lasting much longer than the factory shipped ones.

Later on you might face the same degradation on the headband. After a while I've disassembled it and brushed off all the falling particles on it, leaving a nice "clothy" surface, which doesn't degrade further.
