The M1 CD player looks great. However, pairing via the Bluetooth is problematic and very hit and miss (yes, I’ve followed the instructions). I cannot get it to pair with my B&O wireless headphones. It does pair with my Sony XM5 earbuds, but does not remember them, I have to re-pair each time I use them which is a bit of a pain. It would benefit great from some sort of App to control/choose what to pair with. Overall, great to look at, but functionality is average.
