Yep, I’m sure I recall you having posted that before. And pretty sure Resolve Reviews has said that too (probably got it by lurking here, grin). I certainly wouldn’t know from personal experience.
Since this is still very much on topic, what frequency range(s) would you say you’d have to notch out to get rid of this beryllium thing?
Typically I would most likely say around the 5-7k range but it depends on the headphone
Edit: to clarify I mean that is typically the range that sounds the most unnatural to me, it would again depend on the headphone for which would be the offending range
Whoa! Wasn’t expecting it to be that low. Was thinking it would be up above 10k so my dilapidated old ears would naturally filter it out. Good to know.
Interesting – the Utopia and both the open and closed Vérités show a pretty sharp peak right at 6k … that old HD 800 bug-a-boo.
It’s fine to my ears without eq, but it just doesn’t sound natural at times. It is well controlled though
Aye eq…man people need to research/demo their sets more, that would cut down on that eq malarky and just chill and listen to their music and stress a little less 
I don’t eq any of my headphones except a few for studio usage, but otherwise I don’t eq lol
Oh Metal be like with his Harman…
Etymotic ER4 SR IEMs. Very accurate and neutral, what you hear is the signal they receive.
If you agree with diffuse field that is lol
