What do you think about the sound in the last 2 videos?

I'm asking because I recently started using headphones, which allows me to hear more and remove noise more effectively etc.
However, I'm still new to working with audio, so I might be making mistakes. Most of you watch the videos on your phones, which can also make them sound different.

I assume that most people won’t notice the difference, but personally, I get a lot of satisfaction from improving these little things. I'm also curious whether those who do notice the difference find it too quiet, too loud, or something else 😉
In my own company, I even have a doormat with my own logo 😁

Thank you for your honest feedback and any advice in the comments!
