I’m trying to find where I can buy replacement rubber pieces for my earbuds. I’m talking about what goes on to help them stay in your ears
Life dot 2 replacement rubber pieces
As far I know there are different sizes of ear tips in the package.
You should find out by yourself what size is fitting best and stay in your ears.
The alternative are so called foam buds.
But I dont if these fit in th charging box.
Others could know.
replacements?
Google helps.
