I'm from California (about 40 miles from where they're shipping, actually) and woke up to them on my doorstep. I'm #4602, got the M-Duo in gold and an M6-Pro. M6 so far is pretty comfy and things sound pretty crisp when connected to my DAC and amp. Can't compare to the AKG K553, but sounds much better than the old JLabs I've been using. I want to try the M-Duos soon but the M6 sounds really nice, don't want to take them off lol.
