Yeah, I think you misunderstood but I admit I could have phrased that reply better.
So a discrepancy in monitor translation doesn’t automatically equal a problem with the person listening or how frequencies were managed in the mix. In my case there’s a discrepancy between the SM9’s and the JBL4300’s at 400hz. Also between the SM9’s vs JBL’s and the macbook speakers at 6k. The problem is pervasive through an assortment of mixes.
Like yourself on the cans vs the HS80’s, these are not problems you can address by ‘learning to listen closer’ or ‘training your ears better’. Its a simple issue of learning the quirks of translation and learning to live with the reality that my room isn’t perfect. Of course its my own responsibility to deal with frequency problems regardless. And the best way I know how is to defer to a second set of monitors.
You might say ‘well just learn to manage 400 better on the SM9’s’. I think the best way of doing that is simply using a secondary set that doesn’t struggle with how it represents that particular range.
