Just a heads up in case anyone is experiencing the same issue.....most likely to be those in a more rural location.
I stream music to some Bluetooth Stihl ear-defenders when out in the garden strimming etc. Had a lot of problems with the audio stopping, restarting and generally misbehaving.
Bottom line - nothing at all to do with my end. Apparently quite a lot of the more remote/smaller mobile masts have very limited mobile data capacity and frequently hit 100% load. Now this won't be so much of a problem if you're just browsing...just takes a while for all the bits to come along. But if you're streaming then it's very noticeable. I'm with Three and until they improve their capacity, I now have my monthly contract of £26 a month reduced to £18.
