I think these are a side-grade to HD650, also to Fidelio X2. That doesn't mean these are not great though. I prefer these to pricier Oppo PM-3, Audeze EL-8 and HD700, Beyer T90 and many many more. They are pricier but HE400S is more musical and fits better to my musical tastes. I value fun, engaging signature, and smooth treble over other traits. As I said, these are a side-grade to HD650 but still retains planar characteristics so they are as different as they are similar, and I prefer HE400S as the bass is better than HD650. It goes much lower whereas HD650 has just mid-bass but almost no sub-bass. Also I think these have better highs, crisper and more extended. Mids, I think it's a tie.In the end I'd choose 400S but I wouldn't be surprised if someone else preferred HD650. They are both great.
I think listening to rock with these is a very fun experience. Due to some magic they did, guitar based music sounds amazing and very non-fatiguing, even hard rock and metal. I think, as Matt said, there's some slight upper-mid dip. I'm not a pro on measurements and I may be making things up, but up to now, all headphones I've owned that sounded non-fatiguing and easy to listen with guitar based rock music have had slight dips in upper mids. That said, I'd wait for actual measurements to arrive to a conclusion.
I must also say HE400S has an addicting sound! I can't stop listening to music with it, it's a very nice experience.
HE400S have a deeper bass than HD650?
What amp you used ?
What have the general smoother presentation between HD650 and HE400S ?
