A big thing nobody mentions is ear wax!
It gets absorbed in the foam eventually blocking a significant amount of noise and fidelity, so you turn it up, which drains the battery significantly faster.
Use a toothpick, pull out the foam a bit a couple of mm, squeeze till clean with a tissue.
Be careful not to pull it all the way out or tear it as Sony is shocking for replacements, so are all Bluetooth ear bud companies. Don't compact the foam down, this will also block sound.
Damaged tips also let out sound, you can replace these but super pricey.
Keeping them clean can preserve the life of the battery as well as prolonging the need to replace it.
A repairable ear bud should have cheap and easily replaceable batteries, tips and foam. When one exists I'll buy it.
