I can connect my two H-9s using my iPadAir 2 but BT fails on my iMac. On occasion I can connect the first device but when pairing the 2nd device it kicks off the first device and neither connect. My H-9s are up to date.
Sometimes it will simply not connect to the 1st device. So I am having no success whatsoever. Using my iPad I can connect to both H-9s with no issues.
