Have you tried looking at h-node.org?
That will give you some hints at what hardware works well with GNU/Linux. I personally have a RIG headset with integrated microphone. It was a bit of an impulse buy. It doesn't use bluetooth. It has one chord. I can use it to record my voice, or listen to music. But I can't seem to do both at the same time with it. :( Thanks, Joshua -- Joshua Branson Sent from Emacs and Gnus https://gnucode.me
