I have tiny ear canals. Super tiny. It's fucked up, and I hate it, and it led to an almost routine 3-4 year visit to an ear doctor to have them water-pik my ears so that I can hear, because what most people would consider normal wax-buildup was like that boulder from Raiders of the Lost Ark for me.
One trip to the doctor to get my shit cleared out consisted not of the water-pik, but a different instrument, a tiny, metal loop at the end of a 1-2 inch filament no thicker than a millimeter or two. One or two trips into my ear canal, and I could hear beautifully.
Basically - it was a bobby pin. I mean, it wasn't ACTUALLY a bobby pin, but functionally, it was 95% the exact same as a bobby pin.
Q-tips just pack that wax up against your eardrum until your head is basically constipated with bright orange bullshit blocking all sound from entering your skull. A bobby pin will, if carefully applied, scoop most of that shit right out of your brain.
Look - I'm not advocating you buy a bunch of bobby pins and go gently poking around in your ear canals to remove whatever excess gunk is building up in there.
But a tool that is able to actually REMOVE said gunk, as opposed to packing it into a growing wall of waxy nastiness huddled up against your eardrum? Seems like it might be an overall positive.
