I'm using a Garmin Venu but bear with me please. I've just bought the E8 earbuds and all controls work from the touch sensitive earbuds except turn the earbuds on! This is a disaster as by the time I get to the gym I need to turn them on to get started with them. I can skip tracks, increase volume etc. I previously used B&O H5 earbuds and had no problems. I can see that the Venu uses 5.0 Bluetooth. I'm thinking of getting a Venu 2 plus which is Bluetooth 5.2 and I hope this may remedy this problem. Has anyone had any experience with these Bluetooth versions please?
