The Pro version offers a list of upgraded features. For instance, they include Bluetooth 5.0 + BLE for a more stable connection and longer standby time; waterproof level is now IPX6; smaller and lighter earbuds; audio in both sides when making calls; tapping controls versus pressing; and improved bass. The G1 Pro has seamlessly taken all of the design and feature functionality that consumers loved about the first edition and has woven them into the new model, which offers an unparalleled listening experience. Plus, the earbuds offers approximately 3.5 hours of playback time, and the mini storage case offers an additional jolt of power.
