Clean the ventilation hole on the hearing aid while traveling

A tip for hearing aid users: Maybe you know the thing in the first picture. This is this plastic thing, on which the price tag from the shops hangs on the garments.

Hearing aids have a ventilation hole. If this is blocked, you can hear nothing. That's exactly what happened to me when shopping. I remembered this thing, bought a few socks, removed immediately this plastic part and was able to clean the ventilation hole. Hooray, I can hear again.
