Any lead to improve my bluetooth speaker sound quality?

Using Ubuntu 19.04. I recently acquired a megaboom 3 portable bluetooth speaker, and for its size, the sound is stellar when connected to my phone.

However, when connected to my computer (bluetooth too), the sound is significantly less pleasant. It might be because it is recognized as bluetooth headphones instead of a bluetooth speaker (see screenshot) but I’m not sure.

Any lead to improve the sound quality is welcome.
