It's not good news, sadly.
I explained to BeoCare that I installed an appropriate Airport/Bluetooth card in my MBP 15" early 2011 to make it BT 4.0, and that this made absolutely no difference in wireless performance. A Bluetooth expert on his site explained that I shouldn't have had to do this, but since I did and there was no difference it definitely wasn't the laptop.
Now then, despite my explaining that I found out about numerous incidents where people who recently acquired H8s were experiencing sound drops from wireless use in various equipment (either/or iOS 8 or OS X platform products), here is the response from Christian at BeoCare:
"I received feedback from Denmark, In principle a Bluetooth 4.0 enabled product with A2DP Bluetooth profile should be able to send music to the BeoPlay H8. Practical tests have shown a very differentiated market picture. Most newer computers with updated software and adequate hardware should be able to connect to BeoPlay H8, but we are not able to recommend or support this setup.
