The Challenge
I’m trying to pair/connect these devices:
Sennheiser Momentum 4
XBox controller (Model No. 1914)
What I've already tried (to no avail)
- Followed this EOS guide
-
sudo pacman -S --needed bluez bluez-utils -
sudo systemctl enable --now bluetooth
-
- Updated the system with
eos-update&eox-update --aur&yay - Installed xpadneo
- Tried connecting the USB device to different USB 2.0 and 3.0 ports
- Rebooted
- Using KDE Plasma’s Bluetooth UI to no avail
- Using
bluetoothctlwith some success (see below) - (Successfully) connected the devices to other computers and phones
- iPhone 12 running iOS 17
- ThinkPad X1 also running EOS, but has built-in bluetooth module
See below for specific steps taken
KDE Plasma Bluetooth UI (bluedevil)
No success.
- Click icon in system tray and then “Pair Device”
- Select device from list and click Next
- After a while it fails
bluetoothctl
Some success here, but no valid established connection.
bluetoothctl show

bluetoothctl notes
- I get this notification when connecting to the device
- I’ve tried entering
1234and1111as the PIN, all with the same result - It does connect for a while, but never shows up as an audio device in the system settings and then disconnects again after a while
