But as per syslog it shows device registered as keyboard

Apr 20 11:08:35 doit /usr/lib/gdm3/gdm-x-session[2423]: (II) XINPUT: Adding extended input device "HD 350BT (AVRCP)" (type: KEYBOARD, id 23)
Apr 20 11:08:35 doit /usr/lib/gdm3/gdm-x-session[2423]: (II) event21 - HD 350BT (AVRCP): is tagged by udev as: Keyboard
Apr 20 11:08:35 doit /usr/lib/gdm3/gdm-x-session[2423]: (II) event21 - HD 350BT (AVRCP): device is a keyboard

From the bluetooth device info class its well defined as a headset class. Is the syslog written info a bug or an issue?

The device probably has some buttons, so xinput may use them as "keys". I see no problems of the headset works well.

And the title of the question is not correct. Adding a xinput new device doesn't mean "a wrong device name".
