SoundBuds Curve: how to check the chip

Hi there,

My headset is not powering up and its up to me to fix it since I am outside of the warranty period.

Any idea how to check if there is anything wrong with my chip?

What I have tried:

1 Red light changes to blue light when plugged in to charge.
2 Will not power up regardless of how long you hold the power button
3 Earbuds will not reset by holding the + & - buttons for any amount of time
4 Tried holding power button while repeatedly plugging and unplugging USB charging cable. Didn’t work. (tried several cables and charging sources)

It seems like it is getting power.

Have you tried to maybe get some compressed air in case it has lint in it?
