DT990 premiums vs HE400

[Rockin_Zombie]

hi guys,

I've a choice between these two headphones. Of course, the HE400 costs 100 more. The internet is full of fake reviews (specially some other sites lol), so I came back to my trusted website, the one where I started my "audiophile" journey 5 years ago!

Is it worth spending the extra 100 for HE400? I mostly listen to rock/metal, through a headstage lyrix pro total USB amp. Any input would be greatly appreciated, thanks!
