Recently bought just released Bang-Olufsen H8 headphones (wireless, BT 4.0, atpX A2DP). These paired perfectly with iPhone 5 and my MacBook Pro 15" early 2011, however, sound drops out on the MBP with little to no "provocation" of head turn; forget about range/direct line of sight distance--can't get more than 2' away without sound drop occurring. Avg raw RSSI is approx -72. At first it was thought that b/c MBP was BT 2.1 and the phones were 4.0 they were incompatible. After I modified the MB appropriately with new Broadcom Airport/Bluetooth card to enable BT 4.0 connectivity and found no change at all in sound drops/range, I discovered through conversation with Bluetooth expert that BT is backwards compatible so he wasn't surprised at all with continued sound drops despite modification to MBP. If the sound drops for more than a second or two, the audio somehow speeds up to sync with the place where the sound should be.
B&O's "stellar" customer service told me: "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." I'm sure I can get them to regret that statement, but I'm much more interested in getting the BT headphones to work with my MBP. In my research so far I've found that these phones behave similarly with both iOS devices as well as OS X. There appears to be no rhyme or reason why this is. For me, I have no problem using them with my iPhone 5; not so for others around the globe.
Question is: Is it the MBP antennae or is it the B&O H8 antenna? Which begs the second question: why is the performance so random--worldwide even--for wireless phones, these H8s in particular?
Thanks so much for your help.
