Ok well, I got my eagerly anticipated HE-400 today. Now, my headphone collection includes the Sennheiser HD650 and my favourite closed back headphone the Beyer Dynamic DT 770 Pro. I particularly like the DT 770s because they get to the heart of the music and present it as a coherent whole. Anyway, I’ll cut to the chase on this: the first thing I noticed when I put the HE-400 on (before even plugging into my headphone amp) was a cuppy resonance – similar to if I’d cupped my hands over my ears (try it) – none of my other headphones do this, they all damp this resonance out. On first listening to the HE-400, this cuppines was there and dominated the sound, ie although it was obvious the HE-400s drivers were excellent, there was a lack of cohesion to the music which spoilt the musical experience, in my opinion because of this annoying cuppy resonance.
I’m just thinking that maybe so much research and development has gone into getting the drivers right for the HD-400 that the headphone 101 of getting the interface to the ear has been missed. Thoughts..
Can't say I've noticed the cuppy resonance you are describing. The mids sound extremely detailed and separated, albeit with slightly less-than-black background.
It's a different story if I actually cup my hands over the drivers though, but I don't think that's what you mean.
Edit: are you sure it's not just you disliking the sound signature? HE400 mids are coloured in that it has a mid-mids bump and a upper-mids dip.
