A:Answer These are Class 1 Bluetooth 5, which is the current state of the art--I think the rated distance is 33 feet.
Anyway, I use these with my Apple Watch, which is on my left wrist, and only get a very brief dropout once in a blue moon. Other, earlier technology BT buds that I have owned would drop out regularly and near the end of battery life. These easily handle a two hour session at the gym and they pair almost instantly.
