Well, I got the CKS77 from the ebay seller today.
I initially ordered the CKS77S LTD but like most people here, I received the email about the mixup in the shipping.
I ended up actually receiving the CKS77 red (regular length cord with no extension). From what I can tell, I can't see any physical defects. It looks practically brand new. Some others here mentioned that they had tiny 1mm nicks on their phones. I can't see any defect.
Hooked them up to my mp3 player to do a comparison with my CKM50's.
My initial impressions are rather mixed.
Now, bear with me as I'm still a noob when it comes to the world of iem's and headphones.
These iems are supposed to be "bass monsters" but initial first impression was: "Hmmm where is the bass?" Compared with my CKM50's, the bass on these CKS77's seem rather weak. The bass on the CKM50's were deeper and more impactful. Call me crazy, but I don't feel the bass on these like I do on my CKM50's.
On the other hand, I do notice the "sub-bass" effect on the CKS77's. I can definitely feel the "sub-bass" effect compared to my CKM50's.
Another positive about the CKS77's is the soundstage and the layering of the music. It definitely feels like a wider soundstage and I can feel the layering in the music. Also, it seems to have an "airy" effect compared to the CKM50's which I like very much.
This impression is with no burn in at all.
I dunno, could these possibly be fake?
What's weird is that the red ATH CKS77 I received looks different from the pictures of the red ATH CKS77 online at other places.
If you look here at accessoryjacks site: http://www.accessoryjack.com/audio-technica-ath-cks77-dynamic-solid-bass-in-ear-headphones-black-red-brd.html
You can see there are 2 places where it's red. The audio technica logo area is red. There is also a red ring near the eartip area. However, the one I received only has red on the audio technica logo area. There is no red ring near the eartip. It's black on mine.
I'm trying not to be skeptical. Maybe my expectations were too great after coming from the CKM50's. I'm a big bass head and I was expecting the bass to kick me in the face. But with initial impressions, it felt like the bass was weaker than my CKM50's.
Don't get me wrong, these are great. But, I guess my expectations were too high and I was expecting a huge increase in the bass department, not a downgrade.
Or perhaps I have no idea what I'm talking about.
