Bluetooth earbuds constantly reconnecting (Sennheiser Momentum TW 2)

i'm running currently Kubuntu 20.04 and trying to connect new earbuds (Sennheiser Momentum true wireless 2) but i get the earbuds connected and after a second disconnected, then it tries to connect again, and so on. Я попытался подключить другие наушники (Samsung Gear IconX2018), и он работает без проблем. То же самое с Bluetooth-ключом на ПК и ноутбуком Bluetooth. Запустил также Win7 portable с usb-флешки и обнаружил драйвер от MS, и соединение в порядке.

I had this issue as well and just spent many hours attempting to solve it. I've narrowed it down to an issue with the AVRCP profile (controls the media buttons).

As a work around you disable AVRCP entirely. The earbuds should work fine just without touch controls. Edit the file /lib/systemd/system/bluetooth.service and add --noplugin=avrcp to the end of line 9.

E.g.

[Unit]
Description=Bluetooth service
Documentation=man:bluetoothd(8)
ConditionPathIsDirectory=/sys/class/bluetooth

[Service]
Type=dbus
BusName=org.bluez
ExecStart=/usr/local/libexec/bluetooth/bluetoothd --noplugin=avrcp
NotifyAccess=main
#WatchdogSec=10
#Restart=on-failure
CapabilityBoundingSet=CAP_NET_ADMIN CAP_NET_BIND_SERVICE
LimitNPROC=1
ProtectHome=true
ProtectSystem=full

[Install]
WantedBy=bluetooth.target
Alias=dbus-org.bluez.service
