Just got my (Zeos Pantera inspired) purchase of the Sennheiser Jubilee's in. Just hooked them up to my Audio-GD R2R 11 and using Spotify (on "High Quality"), to give them a burn in.
But I couldn't resist giving them a listen. Wow, this is the 1st pair of headphones that have sounded really good out of the box. Sampling Coffee Table Jazz
I don't know if they'll get any better, but I'll still leave them running for 48 hrs.
I'm really curious to see what removing the outer foam will do to the sound quality.

LGCiSennheiser came into the discussions here and stated that the foam between the driver and outer grille is acoustically transparent (or mostly transparent), and the reason it is there is for aesthetics (cleaner look than all the grille latticework) and to help improve durability a bit in drop tests.
I tend to believe Sennheiser’s designers. I have a preproduction HD 58X Jubilee, which has lighter bass than an HD 650 and yet still has a little black “coin” of foam over the driver. Also, why would foam outside of the driver-to-ear path both increase bass (by reflecting?) and decrease treble (by absorbing what would be reflected back on an HD 660 S, which is an open-backed headphone?)?? I gotta get ahold of some of this wonder foam!
I say that jokingly, as I don’t design headphones, take my reasoning with a pinch of seasoning. It all makes sense to me with what I know at this point, but I’m always learning.

LGCithey make little to no difference. sound tests confirm. I have tested myself and there is no difference. some users are going around sharing that it is a massive difference but its just a placebo effect.

EvshrugPeople have stated that removing the foam it makes a difference so a little conflicting info there from Sennheiser. One day I will remove mine... now dont want to mess around ;-)

jm090Agreed about the placebo effect. The preproduction HD 58X has foam behind the driver too, yet it actually has LESS bass than the HD 650, HD 660 S, and production HD 58X Jubilee. All four variants have had their frequency response charts published in the description and comments here on Massdrop. Sennheiser has also been consistent in their message that the HD 660 S and the prototypes that lead up to the HD 58X Jubilee were all different drivers. The only conflicting reports are subjective heresay on the web from those who want to assert that $150 HD 58X = $500 HD 660 S. Removing the foam might make a minuscule difference, but doesn’t wholly account for the difference between the models.
It’s more of a testiment to Sennheiser that they managed to squeeze in such a high level of sound quality into such a low price point. None of this foam faffery detracts from that.
