"a lot of the hearing aids problem may be the "stub" it is not the correct size and is not in the ear canal far enough. they can be "trimmed" with scissors for better fit."
Costco has all difference sizes of "ear buds". They put the same size in both my ears but the left side was little harder to get in and out. It came off in my ear one Friday night when I took them out to put in the charger. I went to the local clinic the next morning to get it pulled out ($10 copay). I went to Costco right after that and they replaced the left side with the next smallest size while I waited. No problem since then. Costco offered to pay me back but it wasn't worth the trouble to file a claim.
