EP-T27 earbuds Left and Right not syncing

I have just received my new EP-T27 earbuds but I can’t get them to connect to one another. On my phone (S8) I can pair Left and/or Right but I can only ever get sound out of one.

Same problem here. Tried everything in the manual. Each earbud works, but can only get sound out of one.

Me too, worked for a couple of days, only one will work at a time.

Separate to this, I have contacted the Aukey support email address (note that this is support.eu@aukey.com for UK and EU orders) and have been sent a replacement set which functions perfectly! Very happy with the product now I have one that works! Great customer support via email btw - got a response within a few hours.
