Why is the sound quality so poor when connecting a Bluetooth Speaker to my Windows 8.1 Laptop?

[Windows Central Question]

Hi,

I recently bought a Mini Bluetooth Speaker to use with my Laptop. I am an English Teacher in Italy so I do lots of listening exercises, and the speaker would be a great addition...

When I tried the speaker with my LG G2 Phone the sound was fantastic. Clean, clear and good bass. From the PC, it sounds 'Low-Res'....Poor in other words....I have gone through different settings and all seems ok...I can't seem to solve this....

Any help much appreciated...
