No the foam has very clear distance between the driver, so its no way used as a shock cushion, the foam does make the bass a bit more impactful however.

The enclosure plays a super big role in how this particular pair of headphones perform, seeing how the HD598 has a thin cloth and a metal grill ontop of a little bit of plastic grill, i believe this enclosure removes the warmness of the modded completely open HD558, making it sound more...

Had my pair of HD558's for 3 years now, changed its earpads twice already, done many mods onto it, so I decided to go for it and try this one out, in an effort to match or beat the HD598. Modded with the grill completely removed, the silver ring removed, the inner mesh removed, and the...

Actually I believe this is due to the stiffer earpads of the new HD598's. I've personally switched earpads twice already for my HD558 and the difference between 1 year old earpads and fresh ones is almost like the difference between a HD650 and a HD700 (which is a lot) So you can actually try...

the HD518,558 and 598 have proprietary plastic rings stick to the earpads which click onto the earcup, so it pretty much means you can't swap earpads out with anything else

Pictures please when you're done 

Comfort: the HD558 has the same soft valour earpads as the HD598, but the HD518 has stiffer cloth earpads which are not as comfortable. Ear space wise they are roughly similar since they use the same body and earpad design. Sound: I remember the HD558 to be a significant improvement sonic wise...

I didn't expect any differences in the cable but i realized eventually that the stock cable had more wamph in it while the Ebay cable was more crisp sounding though a little bunt sounding at the same time. Overall I found the Ebay cable to be worse than the stock cable so after 2 months of using...

    After the earpad softens the treble will calm down quite significantly and the sound would be a lot warmer.

How about the MOMENTUM On Ears version?

If it's fake I'm more concerned about the material used to make it cause that can affect the acoustics quite a lot.

Just popping out of the blue, thought you might like this video, enjoy!

Agreed, I managed to buy a Momentum On ear by just using the earnings from online art commissions^^ YKAAW when you already are planning what gear to but before you are anywhere close to getting the money to afford them.

YKAAW when you take your open headphones outdoors anyways because they sound better than their closed counterpart. (though they do sound more anaemic outdoors of course)

Agreed they seem to actually be very sensitive to the source quality especially for a portable headphone.

Alright I compared the momentum on ears with 3 cables: Ebay cable Original On Ears Cable Over Ears Momentum Cable Source is the Hippo Biscuit mp3 player Conclusion: Over ears cable > One ears cable > Ebay cable We shall start with the original stock over ears cable. Instruments...

I haven't compared the momentum with different cables yet because I just got the momentums 2 days ago, however with the HD558, I prefer the stock cable because its warmer and smoother sounding, the replacement cable feels crisper but doesn't have as much ambiance in its sound. The difference is...

@Brimstone Nice pic there X3 Also for anyone who has momentum's, they can also use the same cable mentioned above as a replacement to the momentum's thin and rubbery cable     

In case anyone feels the original momentum cable is too soft, springy, thin and flimsy, you can use the HD598 replacement cable instead  http://www.ebay.com/itm/NEW-Replacement-Audio-upgrade-Cable-For-Sennheiser-HD598-HD558-HD518-Headphone-/261255113290? The twist to lock mechanism doesnt...

Momentum cables look like they might work, but don't take my word for it i have not tried it yet.

This has been covered in the earpads thread , the HD598 earcups are deeper than the HD650, partly cause the HD650 has a foam layer inside it which cushions your ears, though for the HD598 my ears don't touch anything at all. They are the same diameter and width, but the HD598 (and 558 and 518)...
