Edit 1:
After some googling ,I found that I need to buy a Bluetooth adapter to connect my PC to headphone,I bought one (Bluetooth Dongle (Cambridge Silicon Radio, Ltd)) and it plugged to my pc and my bluetooth is "On" but my laptop can not detect my device.

After I plugged the bluetooth adpater and run lspci -knn | grep Net -A2; lsusb the result is :

I've struggled for years with bluetooth. The bluetooth stack is very complex and has issues but it gets better year by year.

Here's what I have done and it works great

  • get yourself a Plugable usb bluetooth adapter (Amazon)

  • hot plug it, no need to reboot

  • find and install blueman from the repos (bluez never has worked well for me)

  • power up your headphones, ready to pair
  • open blueman, select devices, find your headphones in the list
  • select setup, choose how you want to connect and click next

  • after a couple seconds, it should pair

  • open sound, scroll to find and select your headphones from the list

Note: You'll have to pair again and select in sound after every boot.
