Q&A Q1. I put M30 back into the case but they are still playing music. -Note：Be kindly noted that when the earbuds are back in the case, make sure they light up and are turned off. After the lid is closed, M30 will disconnect with your phone. Tips for Android users: you can simply turn the volume on maximum on your phone and then you can use the volume control on M30 to adjust for the desired volume. Q2. I have bought M30 and M30 Plus at the same time, can I put earbuds of M30 in the charging case of M30 plus to charge? Or put earbuds of M30 plus to the charging case of M30 to charge? NO, although earbuds of M30 and M30 plus are the same in appearance, but the battery case can't charge the different model earbuds. Please use the original case to charge the earbuds, not mix. Q3.Using M30 wireless earbud for phone call, can’t be heard clearly? How can I do? Tips: 1>Please keep the earbuds clean to avoid stoppage of the microphone; 2>During the calling, please wear both earbuds. In mono mode, please make sure that the other earbud is charged and powered off in the case.. 7 DAY FULL REFUND GUARANTEE ON THIS ITEM IF ANY ISSUE IS FOUND THAT WAS NOT DESCRIBED/PICTURED. 7 DAY STORAGE IS ALSO AVAILABLE.
