I have had very similar issues with my BT-W5 and H95 - great sound quality but very annoying crackles and pops. I spoke to B&O technical support but they say that the only adapter that they have tested with the H95 is the BT-W3 and cannot comment on the BT-W5.
I seem to have lost my BT-W3 but found the BT-W4 and tried that instead. It was recognised by the Creative App for the Mac so I reset it and paired it with my H95. So far, so good with no crackles or popping and good quality sound. The W4 only supports playback at 24 bit 48 kHz so I put these settings into the Creative App. It has a Purple light illuminated which indicates it is AptX Adaptive mode, although the App thinks it is Low Latency mode.
I'll keep listening for the rest of the week and see how I get on.
