VibrantNebula, I truly appreciate that you're trying to help and I have sent in my SteamVR system report and my serial number.
However, I don't appreciate this issue being marked as "solved" when a firmware update has only added a tiny bit of bass. Again, if the Vive Pro's advertised audio details didn't include words like "powerful" and "true-to-life", I would not be complaining so much. Also, if I was alone in thinking that there was still a very noticeable issue, I would stop as well. However, even a reputable website has confirmed it.
So please, for the sake of good customer service, remove the "solved" until it's actually true.
Thank you.
