It’s not the same, they work in tandem on APP but you can force just the Atmos on in settings for other devices

Oh I meant the X line in general, I just specified XC because that’s the one I own, but they’re both beasts in the bass. The XC has slightly more because of the cup housing reinforcing the bass a little but you can get the same effect on the X with EQ. The drivers on both are basically distortionless thanks to the massive double sided magnet array, truly a workhorse 💯 Plus, yours has better soundstage but my room is noisy sadly

The thing I love about my XC is that, since the distortion is so low at 115 DB, you can boost the sub bass sky high and it will shake your soul with zero distortion. They are heavy but extremely capable for sure

If you are going for utmost safety over ear is definitely better. I stopped wearing iem’s due to ear infections and I am EXTREMELY hygienic. Depending on the iem the constant ear canal pressure when you insert them is also bad in the long run

It completely depends what music you listen to. I’m talking levels below what most people would consider their maximum. Like 80db. Many Hans Zimmer songs will cause the problem at extremely comfortable levels, when you still want to turn it up higher. “Why so serious” for example

THD is very useful to determine how a headphone will handle EQ. What authority do you have to declare the driver being far from good? The tuning is flat (by design) sure, but you have no way of comparing the driver design and quality to Sony or Bose.

Flawed logic. It can’t even play infrasonic bass at regular volumes without the driver hitting X max and the voice coil jumping the gap— let alone handle a sub bass shelf EQ. It’s a heavily compromised driver
