8. Precautions and Q & A
A. How to connect back the earbuds? What if they can't be connected back?
What if there is only one earbud working?
After Willful T5 and your mobile phone are successfully connected, it will be
automatically connected to your mobile phone every time it is powered on. If
they cannot be connected or only one earbud works, you need to put the
earbuds back to charging box, and close the cover of the charging box; waiting
for 5 seconds, then open the charging box to connect them to the mobile
phone.
