I have a set of earbuds on a neckband, black rubber, several years old, and the yoke has started to leave a lot of black rubber marks on my shirt collar.
Can you suggest a treatment or coating to prevent this?
The part that rubs off has no jacks or wires comeing out, it's a plain field but otoh, many things might not stick to its surface. It;s curved everywhere.
It wasn't until the 3rd shirt I took the trouble to find the problem, and the first shirt has been washed and it came did come off in the laundry. I'm not a fancy guy but even I think it looks terrible.
This is a combination hearing amplifier and bluetooth-from-the-cellphone and cost about $300 or 400 new, by Bose, and they don't make them anymore. They still sell some on ebay but I'm sure they are as old as mine are.
Doesnt' that mean the battery on new old stock is old and weaker too? If the battery on this wears out, won't a replacement be already half-way as bad, just from age? Probably lithium. (Because I'm consiering buying real hearing aids but I fear they will keep falling out of my ears. The neckband kind do, but they don't reach the ground when they fall.)
Cheaper ones don't give hifi sound, t hough they are still better than nothing.
