Welp.
After my 2nd day with these, I'm starting to mould some opinions.
Highs: I've never heard treble ever quite as "formed" quite like with these. Like, treble never seemed so dynamic, in songs it would only seem like one note, with these I'm really hearing a lot for the first time on the high end.
Bass: As with all open headphones, the sub bass (20-60hz) will always be lacking, you can certainly juice it with an EQ, but you end up boosting it by 8-12dbs and by that time, you can start to distort. I was hoping for more sub bass, but I got what was expected.
Now, moving onto 128-500hz or more specifically 150-350hz, I must've been listening to Speakers too much, because I forgot this region even existed. Most speakers have a hard time handling that range, because it's the low end of the bookshelves and the high end of the sub. So it's generally rolled off. So maybe it's because of that, but the 150-350hz region seems so incredibly boosted on these that it's almost painful when piano notes get to the lower end. I toned it down with an EQ, so it's not a big deal, maybe I'll get used to it eventually anyway.
Mids: I hate describing mids, it's such a large region. I'll let others do that for me.
Other things I've noticed are that, just like the Philips Fidelio X2 I came from, they're fairly loose, but not quite as. If you've got a decent sized head, you shouldn't have to worry, but as someone on the smaller side, they're certainly not tight. Which might not be a problem, because I wear glasses. So they definitely haven't given me any pain yet while wearing.
Looks, not that great while wearing, they still look a little odd, but they're still a beauty to stare at.
Overall, I'd say this is probably end-game for me. With burn-in, mental and otherwise, they should only sound better with time. There's just not enough wrong with these and going by the law of diminishing returns, I can't imagine it being remotely worth it to upgrade anymore.
