I have the earbuds for nearly two weeks! The connection to my iPhone XR is seamless and the deep bass make listening to music on the go enjoyable! The wireless charging case is a new style of living and with the long battery life of the earbuds, you can listening to music almost 3 hours continuously! The only gripe I have is connecting the earbuds to my PC running Windows 10 with May 2019 Upgrade! Pairing with the PC is easy but the connection is unstable and the music fluctuating up and down, and unbearable. I don't think is the problem of the earbuds, because the latest version of the Windows 10 do have press release warning people about the problem of Bluetooth connection!
