Speaker inoperable

I’ve enjoyed using my headphones until one evening when I pushed my right earbud to set in my ear and at point, it ceased to work and has not worked since.

Please advise me as to what I should do because I just want my headphones back.

If it is earbuds, you may want to check to see if there is wax in it. Be careful if you try to get it out with say a qtip and do not try to push it into speakers as you do it

I cleaned the earbud and indeed, there was some wax, in both both buds. However, it did very little if anything at all to improve the quality.
