I think you would like it based on the way you EQ’d the 1770. The bass is less forward and doesn’t resonate at all, it’s tight and punchy. The mids are very balanced, perhaps a little more emphasis on lower mids is what I’m hearing which I really like because notes have so much weight on this headphone. The upper mids are a little reduced but I don’t mind this either as they don’t sound fatiguing. Treble is good in that it doesn’t sound fatiguing and is probably the calmest amongst Beyer’s headphones. Their detail isn’t lacking in any way, it’s actually quite good, but it could be a little better for the price. I put it on the level of the HD6XX and ER4XR, but the 177X beats them in soundstage and imaging. And the 177X still has a little more treble energy. Aside from that they’re rather warm in tonality. In fact I’d say they’re even warmer than the HD6XX.
Honestly, I can’t find anything seriously wrong with them and they’re a very enjoyable listen. That’s not saying they’re perfect, but they’re the best closed back I’ve tried so far and tick a lot of boxes for me.
