A seamless experience with Bluetooth 5 Bluetooth 5 technology provides stronger wireless connectivity for an improved listening experience versus Bluetooth 4 – that means clearer sound, greater range, and a more stable signal. Plus, the earbuds automatically pair with your device upon withdrawal from the case (after the initial but simple pairing set-up) for instant delivery of impressively rich sound and powerful bass. 15 hours of truly wireless playtime The stylish cylinder-shaped charging case has a magnetic pull that provides easy, convenient, and secure closure. As soon as the earbuds are inserted into the case, an integrated auto-charge function will begin charging them instantly. One hour of charge time gives you up to three hours of playtime, and a fully charged case will provide five charge cycles – that’s up to fifteen hours of truly wireless playtime!
