Hello,
had the feedback of myHDplayer-de where I returned my Q10 last week:
"Hello,
we just checked you player with our Bluetooth Components.
We can not figure out an error.
It is working with a couple of meters distance.
Kind Regards"
So my player has no bluetooth problem but can't work with my Headphones. So I have ordered a Zidoo X9s and now my Q10 is for sale, if somebody in France is interested.
