I use one with my stereo paired Level. It works absolutely flawless and just need track skip and volume control. Before I used an Halo but every now and then the Halo lost connection to the network and required multiple resets from both Halo and the Level before working again. Until other Halo firmware is released I gave up on that one.
On the B&O site there is a list somewhere with supported products, that list is quit long. It even works on older products in IR mode. And I have tested with Beoplay A8 and that worked really well to!
