How to keep earbuds from falling out: nine fixes, in the order to try them

Why they fall out

A standard earbud is held in by a silicone tip pressing outward against the walls of your ear canal. That is friction, and three things reduce it. Sweat lubricates the canal. Jaw movement, every mouth-breath and every grunt, changes the canal's shape slightly with each rep, so the tip loses and regains contact. And impact, a stride or a landing, adds a downward tug on an earbud that's heavier outside the ear than in. The tip creeps a fraction each time, and eventually it's out. Every fix below either increases the friction, reduces the tug, or replaces friction with something else.

The nine fixes, in order

1. Try every tip size, including the ones you skipped. Most earbuds ship with mediums installed. A tip that's too big seals for ten minutes, then aches and creeps; too small never seals. The right size seals when you gently pull the ear up and out and stays sealed when you let go. Try the small; then try a different size in each ear, because ears are asymmetric (more in earbud keeps falling out of one ear).
2. The twist-and-lock. Pull the top of the ear up and back with the opposite hand to straighten the canal, seat the earbud, then rotate it backward a quarter turn so the body settles into the bowl of the ear. Most people push straight in and stop; the rotation is what locks it.
3. Seat it shallower, not deeper. Jamming a tip deep puts it in the part of the canal that moves most with your jaw. A slightly shallower seat with the right size tip holds better.
4. Foam tips. Memory foam expands to fill the canal and grips better than silicone, dry. Wet, it grips worse and holds sweat. Good for a treadmill, poor for a soaked hour.
5. Wingtips or fins. If your earbuds accept them (Beats Powerbeats Fit ships them; many sport buds do), a fin braced in the concha adds a second point of contact that doesn't depend on the canal. Some conchas hold a wing well; shallow ones don't.
6. Dry your ears first. Sweat already in the canal before the earbud goes in is the worst case. A towel before, not after.
7. Take the cord off the equation. On any earbud with a neck cable, the cable tugs with every stride. Route it behind the neck and clip it to the collar.
8. Don't adjust with wet fingers. Every touch loosens the seat. Set them once, dry, and leave them.
9. Add a hook. Third-party silicone hooks fit over many stem-style earbuds and turn a tip-only bud into a hooked one. Cheap, ugly, and often the fix.

When to stop fixing

If you've done the first five and they still fall out at the third set, the tip was never going to hold you. The designs that don't need any of this hold the earbud with something other than the canal: an ear-hook over the ear, a clip on its rim, or a neckband around the head. Open-ear versions of all three don't use the canal at all, so sweat has nothing to lubricate. That's the site's whole thesis, and the ranked list is earbuds that don't fall out.
