The internet's full of reviews for them so I kinda knew what I was getting into.
Pros:
They sound amazing, very clear and crisp. Transients are totally on point, I had my mind blown when listening to music with short, plucky and fast bass notes and kicks. (Since I don't have a treated room, they're my main go to when I'm making Kick+bass for my tracks).
While they're open back I wouldn't say they have a particularly wide soundstage, however instrument separation, placement and precision is defilnitely on point.
Build quality is ace, they really look like a pair of premium headphones.
Now for the cons:
- the highs - yes, the headphones have a spike in the highs and they will fatigue your ears if used for prolonged sessions. I was actually prepared for this I use an EQ to 'soften' the highs, however, when using it, a bit of the detail in the highs also goes away. If I really want to listen to the highs in the mix, I turn it of to get an idea of what's there, and when I'm finished with the high end part of the track I put the EQ back on.(I use Sonarworks for this, but only at 40% wet as the profiles they have for the DT1990s are a bit over-correcting)
