Windows 10: connect beats fit pro ear buds to windows 10

My beats ear buds show up on bluetooth device list, but I am not able to pair. I'm prompted by Windows to confirm a PIN, but there's no display on my Beats case, and confirming never works. Anyone else figure out how to do this?

Old bluetooth dongle not work with new ear buds

I have an old bluetooth dongle that works well when connecting my win 10 PC to mobile phone and bluetooth speakers that needs a passcode when pairing. Recently I bought a ear buds and able to pair with my mobile phone without passcode, the ear buds does not come with any passcode. Now when I try to connect the ear buds to my PC, the PC can show the ear buds in its bluetooth device list, but when try to pair it, it still prompt me to enter passcode which the ear buds does not have one. Does it means my bluetooth dongle is too old for the ear buds? If I have to buy another newer dongle, what should I look for? Bluetooth v4.1? v5.0? or whatelse? How can I know what version is my old bluetooth dongle? Please help.

My PC is running Win10 Ent 2004 (OS Build 19041.985)
