Q: Why the Earbuds Volume Is too low ? Even if I have adjusted the
earbuds volume to the MAX ? And I have tested iPhone and Android Phones. l
Phone can do It, Android can’t, Why ?
A: Yes, Android can’t do it. Because iPhone and Android are different
system protocol, ‘Phone system can overcome this, but Android can’t be
consistent. If you are using Android phone, you have double-clicked the Earbud
button to increase volume to the maximum, you still think the volume is a
little low, you can try to adjust the volume by your phone. Hope this answer
will solve your confusion.

earbuds can’t connect with each other when take out of the charging case?

bluetooth will go with the primary connection.
