I also noticed Transparency mode improved. Or it could be some kind of placebo.
In the past, transparency mode would make the music a bit too quiet in an environment with a lot of white noise.
Now, even with transparency I can hear the music clearly while also being able to hear my surroundings.
I use mine with transparency at work and don’t feel the need to remove them at all (unless someone is talking to me obviously not to be rude).
I sometimes even forget they’re there tbh. They fit me perfectly out of the box.
