For a headphone test like that, it won't really be DBT, because you won't be 'blind', even though you can't see, you'll be able to feel the difference between the ety and the HD600. It will be very obvious which one you are wearing. It wouldn't even be single blind, because the person switching plugs for you will know which is which also.
What you are doing is just a comparison test, which is A-Ok, in fact, we like them a lot
You aren't trying to make a scientific claim as to which is the superiour headphone, you are just letting us know which you prefer, and in what areas. We like reading those.

at the end. I guess I have to have a few more posts before I use stoopid/ignorant humor so people don't take me seriously.
to let me know you are being silly, so I don't have to lay upon you the wrath of the DBT Nazi.
