My purchase date was 4/20. Which was not bad since that was Fri. afternoon/night here so they didn't go out till Monday at least. 8 business days wasn't bad for the free shipping.
Have to say the CKS77 sound very much like the old Maxell flagship CN40. A bit more bass/midbass on the AT and a bit more clarity on the Maxell. Though more burn in is in order on the AT. The Maxell is vented in the front Beta Brainwavz/Sony EX90 style and the CKS is closed but for the one small vent hole so it should certainly show more bass.
Answering Dsnuts question before, I don't think they are that bassy. They did have a bit of extra midbass that was improved going to the right tips. I see more what the Z02 owners are saying that still add some contour(having owned the Z02 previously) with the CKS77. Real bassy headphones have me EQ down the extra bass. The CKS77 are fine with the right tips. Pretty much what I thought the AT Solid Bass would have in the higher range 7X and 9X series. My modded ASG-1 has tighter and more authority to the bass notes. The 77LTD sounds a bit softer and has less feel/impact. The ASG-1 sounds more like a headphone though and is quite special in that way. The ASG and the Sony HPM-78 go quite low so the CKS are not quite the kings of sub-bass but belong with the other kings of sub-bass not having set themselves apart as of yet. Now you can understand why I said in the past and coming from my experience that the SHE3580 really doesn't quite do sub-bass
but falls short. The GR07 recently tried to run with this bunch but couldn't keep up in bass quality(mainly vs. ASG-1)/quantity and low reach.
I am happy with the CKS77LTD so far. It fits in with my stable of big sounding, deep staged, low reaching, textured, open sounding with quality weighty vocals bunch. They also bring the fun and engaging factor and some technical ability. I really like the extension(77LTD is a short cord) since the HPM78 and CN40 are also short cords and my Maximo extension cable is a bit kinky being fabric covered so it is a nice improvement. The LTD is certainly a nice looking earphone as well and quite handsome in the red.
