What happens when your earbud gets weak?
Many people buy a new pair.
But some earbuds are repairable.
This means you can fix them yourself.
Mika uses her earbuds every morning.
One day, the music stops early.
The battery is old.
So, she opens a small cover.
She takes out the old battery.
Then she puts in a new one.
The music works again.
Here is the surprising part.
She does not throw everything away.
She keeps the earbuds she likes.
A small fix can give them more life.
Sometimes, old things only need a new part.
