Hi, I've got the H8 since x-mas, and have experienced annoying dropouts when using these with my Samsung smartphone. Not that much dropouts when using the H8 with my iPad, but it is more convenient to use Spotify on the mobile than on the iPad when travelling....
The Samsung supports aptX, but only BT 4.0. The H8 now supports BT 4.2 in the latest sw upgrade.
My question is: If replacing my smartphone, should I go for an iPhone 6s or a Samsung S7 (with BT4.2 and aptX) to have the best listening experience (i.e. least dropouts) with the H8?
BT is backwards compatible. The local B&O store sent me on a WILD odyssey in Feb 2015 by saying that my dropouts were caused by my MacBook Pro (2011) being equipped with only BT2.0. Bull. Folks at Bluetooth chuckled at that notion and told me that it was unnecessary for me to have upgraded my Bluetooth/Airport card to one that is BT4.0 because BLUETOOTH IS BACKWARDS COMPATIBLE. Upgrading anything in your Apple computer must be done on your own because none of the Apple "geniuses" or authorized repair centers will install equipment that wasn't part of your original build. In short, I had to install it myself with the aid of very good video instructions. The result was less than disappointing because all of that work didn't improve the dropouts. Last year I replaced my computer with a 2015 MacBook and the dropouts seemed to disappear (my dropouts were occurring within 2-3 feet of the laptop) until I traveled >10 feet from the laptop and then only intermittently.
Noteworthy to point out that initially Beocare tried to deny the serial number thing and said "you shouldn't believe everything you read on the internet." Ultimately, though, they succumbed to reason and contacted the local B&O store to authorize them to provide a warranty replacement pair (I asked for the black one) for 2 reasons: one - manufactured after the alleged antenna redesign; two - it's the color I would've wanted from the very beginning but was not available at product launch.
This experience has taught me to look at the B&O brand differently and to not patronize the Boston B&O store at all because of their horrible treatment of a potentially good customer. They're a franchise and have proven to be most unhelpful post sale.
