My initial impressions to these headphones weren't as good as I expected. I'm expecting that I will be overjoyed the first time I listen to them.
Maybe the primary reason for it is that I'm really tired that night, plus my ears are also exhausted due to the loud GR07 the whole afternoon. lol.
I've had the chance to listen to them the second time last night (too busy to listen to them every night on week days) and WOW, they are incredible!
They are so detailed especially the highs, I heard the cymbals like I never did before, they have body in them, but crisp and crystal clear. I don't know if it's a common thing in full-size headphones since this is my only one, but damn, I cannot stress enough how happy I am with them last night. They are so insanely transparent and well textured. The bass is tight (may be even tighter than the DT 1350!).
About my complain in the mids department, I think I'm comparing my DT 1350 to them a little bit too much. They just have different voicing but neither is wrong. Actually I think my beyer is the one that is over emphasizing the "aawwe" sound in electric guitars, the HE-400 is more flat and true. Once I accepted how they're voiced and stop insiting that they should sound close to the beyer, I understood how it really presents music and it is freakin' good! At first I admit I concluded that they don't or won't really do well in rock/metal or when a good distorted guitar tone is required, but nope, I was entirely wrong. I love how they do those things as they are so transparent and still has a sense of rawness in them. Maybe a little bit more refined compared to my DT 1350 but that doesn't make them less adequate to handle those types of genres. I listened to RATM and the guitars sounded really good. And The Faceless tracks really show how fast they are. There isn't really a song where they seem to hold back or have a hard time rendering. I throwed every complex song I have on them and they render it sooo effortlessly. Love them! I can't wait for the weekend to spend more time with them.
Thanks Matt, won't be so convinced to buy a $400 headphone (even if it's planar magenetic) if not because of your thread!
