Was looking at portable speakers and this site scores the sound quality of a Sony SRS XB10 at 64 whilst it gives a Bose SoundLink Revolve a meagre 38. The Bose was rated as #2 portable speaker of 2019 by Techradar whilst the Sony didn't even make the top 10 which is not surprising as the XB10 is at the budget end of Sony's offerings.
So whilst this site is useful for comparing factual information it isn't to be trusted when it comes to issues of actual quality.
