SN on this set is #136 fwiw.  I'm not sure I've heard a difference in different HE90 sets from the same amp, at least when both sets have ear pads in similar condition.  Changing out my new earpads with the old, flaked out ones does make a bit of a difference though.

WTF couldn't Sennheiser release an Orpheus II instead of the craptastic HD700?!?!?!?


Because Beyer has nothing to compete w/ the HD800, why bother?  I think the recent proliferation of $2K+ phones has Senn dusting off the schematics though.

Orpheus placed in historical context didn't do that well. Then the HD580+ series came along and became a cash cow for Sennheiser. If the HD700 is the ultimate evolution (/bastardization) of the 580s then here's hoping that Sennheiser pops out a couple of more duds so there's a greater incentive to take a second look at stats as statement products.

It's me so naturally the same set of earpads and my slightly modded arc assembly.  This is a headphone arc not made for vikings...   ;)  All driven off the same amps and with bias box in the middle.

It's obvious the HD800 is diffuse field, HE90 isn't so I'm not sure what claim of neutrality Senn is making w/ the HD800 unless one assumes diffuse field is neutral.  A claim I've had a little trouble w/ going back to the ER4.

Actually the HE90 is much closer to DF.  Here's an old Headroom graph of the HE90 and they normalize to DF.

http://cdn.head-fi.org/1/15/158c85a7_OrpheusFR.png

The HE90 Is very close to DF with a few bumps and dips but mostly seems (never actually heard it) to come off as warm due to a slight tilt to the bass.

The HD800's FR is either just something they pulled out of their ass or those graphs they send out are based on a very odd sampling of heads and ears.


Of course like I always say, it's impossible to have a neutral headphone because without moving a lot more air you can't make something sound neutral and feel neutral at the same time.  The ER4 goes all the way to the sound end of the spectrum.

We'll see how you feel about that later when I drop off my rig.   ;)

@ Mav


As for DF, the ER4 uses it and the UERM/B2/DBA all seem to share the same basic DF signature.  Senn claimed to use DF in tuning the 800 and the curve looks similar to those other DF phones to me.  Maybe DF is supposed to yield a 'warm' sound but my experience w/ these phones has been anything but tbh.

And I respectfully disagree.  :-)

The engineers didn't even want to admit the differences in the amps until I showed them my proof...   

That must have been a good moment.  I would like to confront Beyer's "engineers" with a pair of empty T1 cups.  There are a number of people in the ortho thread, and on this forum that would have made a much better headphone given their resources.
