Hi smok3
the HD265 is said to sound a bit muffled.
To my hearing, the bass range is a bit exaggerated, so any bass boost should be turned off. To me this is not a problem because I don't like any equalization

Upper bass, mid and high range sound just like my old, beloved KEF 101 or TDL MC. Not muffled, not too sharp.
If you like older british speakers, I think you will also like the HD265.
