FAQ

Q1: Why did my earbuds cut in and out?
A1: There could be a few things that are causing the problem,for example:

1. Low battery
   When the battery for your earbud is in low battery status, it’s going to cause more disconnections. Keeping it fully charged will prevent many of these issues with cutting out. You just need to charge it up.

Q2: Can’t power down the earbud without disconnecting from the phone first?

unnecessary trouble, hope this can get your well understanding. Thanks.
