I bought second-hand headphones and my problem is that they smell bad.
The smell is a bit like a tshirt you would wear for a few days without washing it and it comes from the ear cushions. I suppose it's sweat from the previous owner. Those cushions are made from a leather-like material, I'm not sure whether this is real leather or not.
The day I bought them, the smell was strong enough for me to feel it when driving the car with the headphones on the passenger seat. Now I can still feel it a little with the device on my ears.
What I tried:
- Dish soap
Both techniques could reduce the smell significantly but it's still there.
Of course I could completely replace the ear cushions but if they can just be cleaned that would be better.
