Thank you Don...for helping out with your measurements. What is striking is the difference between the HD598 and Momentum in terms of ear hole size.
Momentum's clearly are not a good choice for those with larger ears based on the fairly considerable size difference.
Can HD600 or HD650 owners kindly measure their ear hole size vertically and horizontally to compare with HD598 and Momentum?
Thanks again Don and welcome fo the forum!
PS: do you notice much size difference between Momentum and HD598?...do you have big or more average sized ears?
i would say i have average sized ears that lie fairly flat against my head.....
that is probably the first time i have had to describe my ear size!
the momentums fit perfectly for me, very comfortable and sound pretty excellent with the Studio-V 3rd anniversary edition.
