Can't pair Sony speaker CMT-X3CD with chromebook & smartphone

[CarterUSM]

Hi

I cannot connect my above Sony speaker with either my new Chromebook or my new smartphone (although I've been able to connect it to my now rather obsolete IPad). When I am trying to connect it to the Chromebook, the speaker name is appearing within 'Settings', but as an 'Unpaired Device' and ultimately failed to connect. 

Is it possibly because the Sony speaker is now relatively obsolete compared with the newer generation of devices, and it just won't be possible to connect to them? Or is there another reason for this?

Any assistance would be gratefully received. Thanks in anticipation.

Hi CarterUSM, since it's connecting to another device, that means it might be a compatibility issue. The BLUETOOTH Standard version is 4.0. Profiles are only two: A2DP (Advanced Audio Distribution Profile)
AVRCP (Audio Video Remote Control Profile).
