First thing first, I'm definitely not looking for a "fun bassy headphone" for the simple reason that I don't find bassy to be fun but rather tiresome. I typically don't enjoy headphones with that description.
Using your link I get barely audible sound with the generator set to 20hz at normal listening level and definitely a long way from what I'd describe as "healthy". With the Pro80 on the other hand I can feel the vibration.
@Humblepie does also mention the bass roll off so either they changed the tuning or there's a pretty big unit variation. Removing the bass doesn't make the headphones balanced or neutral in my opinion but rather unnatural sounding.
I don't use bass boost or eq and have no need doing so when I can just listen to a pair of headphones with subbass.
You're right though, the Pro82 is definitely not what I'm looking for and I'm honestly having a hard time understanding that anyone can appreciate this lack of dynamics that makes the sound really two dimensionional. I'd go as far as saying that these are the least dynamic headphones I've ever heard. Once again this is very different from your own and others earlier impressions which once again raise the question about a silent revision (especially as
@Humblepie also notice the lack of bass with his new pair as well).
I was hoping for an upgrade to the Pro80 and imo the Pro82 is no such thing. Once again I think the two are quite similar sounding except for a lot less dynamics in the Pro82.
Do you have both a new and old revision (with different cable lengths) or have you just been told that there were no other changes made?
I'm honestly really surprised about how different we hear them and I think that it would be important to potential future buyers if we can find out the reason for this.
The tone generator is a great tool btw, thank you.
Edit: I'm using the LG G5 with the Hifi Plus module as a source.
Edit 2: Tomorrow I'm going to try some different pads on them to see if the sound improves.
