I’d say there’s a few primary factors at play, most of which folks have mentioned here. Neither of you are totally wrong, just maybe not considering or know the bigger picture.

1. everyone has slightly different hearing, and their ear/brain actually becomes accustomed to whatever they typically listen to. So, a different sound profile may sound wrong, even if it’s technically “right”. This is likely part of why your friend hears it as good, and you hear it is wrong - he’s used to it, whether it’s good or not.

2. game audio can’t often be trusted, given it isn’t nearly as high of a priority to make it neutral or natural, and compression for the sake of file size often plays a part. Ultimately, games vary a lot and the makers don’t necessarily have “studio” or “reference” audio gear in mind.

3. these beyers don’t play well with compression from my experience due to their treble peaks. To me, it made things sound harsh and digital in a way. They are also on the lean side for the vocal range, lacking things like “warmth”, “body”, and “fullness”.
