It's entirely possible it was damaged in shipping, planars are finnicky at times.
The "thack thack" sound is something that I think most Audeze headphones have, and it's not considered defective. I started having it in my LCD-3 after the drivers were replaced.
In my EL8 though, I don't have this problem. I think they managed to eliminate this in one of the revisions.
