Another way to use wireless earbuds with your Kindle Fire is to connect them to a Bluetooth speaker that supports the AptX codec.

It takes around 1.5 hours to fully recharge the Rulefiss Q38 Wireless Earbuds and 2-3 hours to charge the case.

The ear hooks help keep the buds secure. Take out both two EarBuds and hold MFBs on both of them for 1s to power on. Then double tap MFBs on both EarBuds separately and wait until two of them auto connect with each other (LED blinks red and white for 1s). Lithium-ion batteries slowly lose capacity over time and charge cycles. After 2-3 years, you can expect up to 15-20% reduction in play time per charge. This is normal and the earbuds will continue working, but battery life will be shorter.
