Looking for possible options for a hardshell case for transporting my Beyer DT-770's to and from work. I know there is the Slappa case (link) that I have seen used (example here).

I am curious if there are other options that folks are using. I don't mind spending a couple bucks to keep these babies looking good. I would like if its got a way to attach a carabiner to it so I can attach it to my briefcase.

I am also debating doing this mod (link) to allow for use a custom 3.5mm cable to be used so I can make a long, medium and short one for using with different devices.

Thanks in advance and MERRY CHRISTMAS!
