Frequently questions & answers

Well, unfortunately, Android is incapable of doing so. Because the iPhone and Android operating systems employ distinct protocols, the iPhone system can overcome this, but Android’s can not.

Why are my Bluetooth earbuds cutting in and out so frequently?

The issue might be caused by a number of factors. For example, consider
(1) a low battery. When the battery of your earbud is low, it will cause more disconnections. Many of these concerns with cutting out may be avoided by keeping it fully charged. All you have to do now is charge it up
(2) Beyond the Bluetooth range. If the distance between your Earbuds and the device to which you’ve connected them is too large, your connection may break. If possible, keep the distance between the earbuds and your device under 33 feet (without obstacle),
(3) Check to see whether there is a microwave oven or WiFi nearby, since they are more likely to cause electromagnetic interference and cause signal disruption.
(4) If the distance is within 33 feet, apply the following steps:
Replace the earbuds in the case and close it; delete “«88” on your phone,
Open the case and reconnect the earbuds with your device after 10 seconds. If the earbuds still won’t pair with your device after reconnecting, attempt the instructions below to reset them.
