New EarFun have arrived but although both buds are connected - whichever bud i connect last is the only one which plays. So there doesn't seem to be a fault with either one as they both are able to play music.
As they have charged only for 10 minutes i'm following advice to charge for 2 hours - though i'm not sure how that alone would solve it. The issue that either might be dirty (brand new) doesn't seem to the case if both are able to work individually?
How do I get them both to connect and play at the same time as expected?
