Bose QuietComfort 35 is a bluetooth headphone, which can be used on ArchMerge(D).

The extra you need for bluetooth is already installed on ArchMerge(D).

Sometimes you need to switch your headset off and on again to reconnect to your machine when you reboot your computer.

Enable pairing on your headphone.

User manual at bose.

Go to the bluetooth icon, click on the bluetooth icon and connect to your device.

Go to the sound icon (bottom right) and select your device.

See that the Output profile is High Fidelity Playback (A2DP sink). MUCH better sound than the other setting Headset Head Unit (HSP/HFP). As long as you do not see this headphone in your sound settings, you guess it, something is wrong. And in bluetooth nothing seems that simple. Then you can start googling. May I suggest the archlinux guide as a start. I hope the installation was a success. A screenshot of the settings in pavucontrol.
