Whoa didn't even know about all these comments. Kinda forgot about this thread for a little while

How is the bass of the HE-400 in comparison to the HD25? I see that you've got the adidas version in your collection
I DID have the HD-25, until I sold them for the Beyer COP not too long ago. The two are on different levels and with good reason. The HD-25 has fantastic punch and attack, especially mid-bass, but I find it loses momentum as it reaches lower down. On the other hand, the HE-400 sounds a little mellow compared to the HD-25 in terms of attack, but has a fairly linear response in the bass. It is able to go down low without losing much momentum.

I agree with the review love these phones warm yet exciting sound stage is much deeper than the k702 more engaging
They are mildly warm at best, but I can see why people agree on the HE-400 being a little warm. Deeper than the akg x70x? Not too sure about deeper, but I find it has much better layering and it's not too distant where the x70x sounds distant, separated, and airy. As you can see, I'm not a huge fan of the x70x as I find the soundstage to be a little too overdone.

Nice review. One of my Top headphones. The Velour Pads are a must IMO. Also I did a mod here : http://www.head-fi.org/t/635480/simple-but-successful-mod-on-he-400s
It really helped with the weight and comfort and makes this headphone wearable for much longer.
cheers
Hey thanks. I don't know if I want to get velours at the moment because I'm saving up to replace this with the HE-500. It's going to be a sad moment for me, but the HE-500's mids and treble is too good to pass for me.

How long are you guys burning these in for? I just got my pair right now and while they sound very good, I'm wondering if burn-in is relevant for planar magnetic headphones.
I would say give the HE-400's a reasonable 100~ hours and make sure to give it breaks in between. Many don't believe in burn-in, many do. I'm one of the people who do believe in it, but with that said, I also believe in brain burn-in as well.

The treble mellows out a bit after maybe 100~200 hours. Do note that this may be 90% brain burn-in.
Honestly just enjoy em and have your brain adjust to the sound signature.
I did find the HE-400's treble to be a tad unstable around new and as you stated the treble does smooth out. I believe in physical burn-in myself, but as I stated above, I do believe in the brain getting used to the sound as well. Eh, I believe in both!
That last sentence shouldn't be taken lightly. Like Currawong's custom avatar says, Enjoying the music comes first
