Guess that I'm not either ......
Under what conditions would that NOT be worth it?
When statements like this make you red-faced for a bit. "The beats Pros are more stylish, and definitely much more rugged than the no-frills Beyerdynamic DT 990 PRO" that was from Headphoneinfo.com
Tempting to send them a German Maestro 8.35D and ask them if the Beats Pros are more rugged than those tanks. Honestly...
And the HD 650 comparison too
I can't vouch for the 650's build, as it looks to me a bit plastastic, but I haven't used it so take it with a shaker-full of salt.
