I don’t understand why people buy these nice and expensive headphones only to use Spotify, arguably the worst quality music streaming service that exists. It sounds so bad compared to Apple Music, YouTube Music, Tidal, Deezer, or even Napster. At least you are getting lossless sound with those, it won’t be the same as having a ripped flac from a CD but anything is better than the AAC 128/320kbps that Spotify offers. It just bothers me when I see photos of headphones on this sub and then they have Spotify open in the background, I just can’t understand!
I have both Tidal and Spotify. I cannot reliably tell the difference between Tidal’s FLAC 16 bit 44.1kHz and Spotify’s very high setting once I volume match. Volume matching is huge in quality perception. Another possibility is that you straight up don’t have 320kbps enabled in Spotify settings and are hearing the ultra compressed lower res versions which do make a big difference. I also have some extremely transparent and high-end headphones, so the gear isn’t the limiting factor.
