RMA BeoPlay H8 - Update:
BeoCare replied to my email after four days in a very professional manner, even appologizing for a delay in answer. They aknowledge the problem with BT-reception, although in a very mild manner :) :
"It is correct that the BeoPlay H8 has received a slight hardware improvement, which seems to have improved the Bluetooth in the headphones."
They did offer me to send my H8 for a diagnostics so UPS collected them in Stockholm the day after. They are now on their way to the B&O diagnostics centre in Germany and will be either replaced or returned. That remains to be seen.
Hope I'll get a pair of new one's with the hardware improved reception - my H8s audio does drop out a lot when they are in trousers or in any pocket virtually.
About the cable - BeoCare did not give a reasonable explanation of including just audio cable (with no mic & control) in the box. Audio cable from my H7 works perfectly with H8 for example. They did not however forget to remind me that I can puchase such cable from B&O, which I find slightly offensive. Marketing a product of this level with such a price should include flawless cable replacement without feeling of being drained for a few extra bucks. Too cheap for such a Brand if you ask me.
So, now it's a waiting game - I already miss my H8 :)
