Please stop the B.S about “audiophile” headphones or whatnot lol. You listen to what you like and if you like it, then excellent it is. There is no need to have one standard where everybody agrees it is “audiophile-quality”.
Besides, the term audiophile may be evolving. Older generation audiophiles may lean toward a shrilling high end with really flat EQ while the bass is really “weak” while newer generation audiophiles lean toward a less sharp high with punchy bass and adequate, powerful mids...
For me, the H9i is it. Punchy lows (not overwhelming), powerful presence on the mid, although occasionally too shrilling highs. Then there is the benefit of living in these days where sound tuning is just a ToneTouch away.
Finally, I’d like to say that Bluetooth headphones are now good enough to be virtually indisguishable from wired ones. Maybe unless you’re extremly critically listening for differences, I don’t think you’d head a difference. When I tried Focal Utopia, I was expecting mindblowing stuffs, but yeah, being used to wireless pairs, I didn’t really hear any mindblowing sound. Don’t get me wrong, it was really good. But then again, that Utopia was on lossless through Mac.
If you think Bluetooth headphones are not good, don’t blame the headphones themselves if you are using Android/Spotify.
I find iPhone through Apple Music gives the best output from a mobile.
