The foam at the mic and the earphone have torn off. On searching for replacements, the cost of buying a set of replacements is almost the cost of the headphone itself.
Without the foam, sounds do not get captured well with the mic. There's a lot of what sounds like 'static'.
But when I covered it with a small muslin cloth, sound was good. So at least temporarily I could use cloth for the mic, but is there a neater, more durable solution to replacing it? Something that serves the purpose that the foam was meant to (at least I could see why the foam is necessary for the mic, but for the earphone I'm assuming it's just for comfort).
Any easily available material that's as good or better than using that flimsy foam that easily tears off?
