I got these today !
Warning: Spoiler! (Click to show)
Great photos! I hope you enjoy them as much as I do :P
I would like to believe you...but the article I linked shows the considerable cup size difference between HD598 and HD600/650. Further the reviewer
refutes what you write. To my eye, the HD598 has clearly smaller ear openings compared to the HD600/650.
You will make me a believer if you post pictures of each headhphone with a major/minor diameter axis comparison. Otherwise I will side with the reviewer.
Its pretty well known one of the reasons the HD600/650 is so popular aside from sound signature is the copious amount of room inside the ear cups for big ears.
i have used both the HD650 and the HD558 (different model but same dimentions) and both the earcups are very big. the Momentum has much smaller earcups like the HD202.
i would get back to you when i get the chance to head over to the audio shop this friday.
I concede your point about the Momentum being smaller...however I have tested both the HD598 and HD600/650. To me, I believe the reviewer is correct. The ear pad hole feels larger on the HD600/650.
If you have access to HD558/598 and HD600/650...a dimensional comparison would be greatly appreciated. Since the ear pad holes are asymmetric for all models, two dimensions for each would
be preferred. I actually am interested in the HD598 in fact for its fun sound signature. But because of my big ears, I am more inclined to go with the HD600/650 because again my perception agrees with the link I provided.
So, if you could perform this dimensional comparison, it would be most helpful to those of us with bigger ears seeking a comfortable fit.
Metal sounds good on these, but there are moments where I would prefer a little more 'attack' or 'crunch' in the guitar treble. (The treble is slightly veiled; in volume, not detail).
But for complex multi-layered symphonic metal, ALL the details and instruments are present and separated perfectly - I'm thinking Serj Tankien here.
I'm not really a metal-head, I just listen to a couple of thrash bands because cousin influence (he used to lead a thrash band), but in his opinion my Momentum suits very well to trash or metal in general, because they feel fast, and fine distortions of the guitars are really well rendered.
I guess we'll have to wait for more experienced opinions.
There are already too many portable folding cans available. Sennheiser needs to regroup and make a great sounding headphone. They lost the plot after the HD600. They had the perfect pads and housing to compliment their drivers. Add on an after-marker cable and many found sonic and musical nirvana. If they could come up with a smaller version of a similar design...
first post on this here forum, thought i would help everybody out with the dimensions of the cups.
i have the 598s and the momentums.
598s - height 70mm width 40mm
momentum - height 52mm width 34mm
and for any americans out there
598s - height 2.75in width 1.57in
momentum - height 2in width 1.33in
If the earpads were totally leather the sound would be completely different. Leather doesn't really let air or sound through (much), but opening up the earpads with fabric allows for a bigger soundstage, and more air.
I can only assume (from my past experiments and DIY projects) that a fully leather earpad would make the bass bloated and take away the 'air' to the sound.
Bose use a similar technique on their triport headphones - it's a small enclosure, but with quite deep earpads made of thick foam surrounded with fabric.
Take away the foam and the deep bass disappears. I even put the foam into other headphones/earpads and could hear the bass suddenly extend and increase in volume.
