The bluetooth connection between my brand new Garmin Vivoactive 4 and my Jabra 75t earbuds appeared to be good. To test the connection, I put my watch in one room and went to the other side of my house and there was no interruption to my downloaded music at all (with a gap of 40-50 feet). I was now confident in my purchase. I then went walking in my neighbourhood and the bluetooth drop off was instant and continued stuttering my music until I got clear of all houses. Once free of houses the music flow was perfect. Then a few cars passed me and the bluetooth interruption was evident once again until they passed by. Clearly there is bluetooth frequency interruption between my Garmin Vivoactive 4 and devices inside of the houses and in the passing cars. Just to be clear. my Jabra 75t earbuds work perfectly when paired with my Iphone as do a pair of Sony earbuds. Why is this happening on an expensive watch made by a reputable company like Garmin ? How can I fix this ?
