Thanks Takashi! that repo does not seem to have tumbleweed... I will probably get away with factory but I see pulse* are disabled... is bluex from there enough/
PA itself is same as TW in my case, it's all about the
pulseaudio-modules-bt, which is a downstream PA module that supports
more features.

Hi,
I am on tumbleweed and I try to connect a pair of bt headphones. they
connect fine and even if they are correctly detected i seem to have
available only the output profile...
I have another pair of bt different make and that one works correctly
both profiles are enabled.
Now I try to understand if this is something missing in pulse (config
or patch) or
simply these headphones are not supported as input devices.
(snip)
Bluetooth headphones support is unfortunately lacking in pulse audio
and, AFAIU, the kernel as well.
There is a merge request that works towards improving this
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/288
but it does not seem like it's going to be merged soon. I am running a
slightly older version of that code together with the hsphpfd daemon
mentioned in the above MR.
I've linked the needed projects at [1], but unfortunately the
pulseaudio one is broken and needs resolving.
Hope that helps,
Robert

FWIW, I have other downstream variant of bluetooth PA module with
additional HPF fix patches, available in OBS home:tiwai:bluetooth
repo:
  https://build.opensuse.org/project/show/home:tiwai:bluetooth
The relevant bugzilla entry is boo#1167940:
