Good to know- These Goji earbuds use Bluetooth 5.3 for a solid connection, so you won't get cut off mid-call- They'll connect automatically when you take them out the case - no fiddling around in menus each time- Use the earbud touch controls for music and calls when you're on the move- The buds offer up to 4 hours of battery life and can be charged up to 2 times in the case
