Yikes that feels like such an oversight. I don't really understand the multifunction button then. It would be perfect if it had the options: wireless, bluetooth, wireless + bluetooth, aux. Feels like kind of a step back if I have to either turn off my pc or dig behind it to unplug the dongle...

If possible could you elaborate? Are you meaning to use with the headphones or for the dongle? Appreciate the help.

I've been enjoying my penrose (first wireless headphone) so far. There's some white noise but I don't notice it when music is playing. There's been a few bugs which will hopefully improve as time goes on. I've had my volume shoot up to 100 out of nowhere and had to rip them off my head quick...
