I'm also looking for a solution to use my PC as a source for my Sony WH-1000XM3.
aptX Low Latency is of course preferred when gaming on the PC. Also want the mic to work.
I don't have a strict budget though, so cheap is not necessary. If I get a "premium" adapter I also want it to work with other Bluetooth peripherals. Mouse, keyboard, phone, laptop.
Is this true: A bluetooth dongle/adapter with aptX HD / Low Latency don't have data connectivity, only music? Then I need 2 dongles for my need above to work?
Sorry for highjacking your thread but we have similair needs
