Got my ATH-CK7 Today! (Versus Sony EX51 & Etymotic ER6i)

I probably paid a premium and bought my ATH-CK7s via Amazon.com:

As I am sure many of you can remember, I posted like 15 threads trying to pick people's brains here about what to get for around $100 to replace my Sony EX51s (HPM-70). After having decided against the V-Moda Vibes due to their lack of isolation, my decision boiled down to the ATH-CK7s, Etymotic ER6i, and Super.fi 3s.

Well, the CK7s came today, and not only did that happen, I found out that a co-worker had his Etymotic ER6is with him as well! So we both got to do a side-by-side comparison (keeping in mind that my CK7s haven't been broken in). We did the "comparison" on an un-amped 30GB latest-gen iPod. He listened to his ER6is and listened to mine and I did the opposite. Our conclusions were the same:

(HIGHLY UNSCIENTIFIC)

Comfort

The mid-sized tips on the CK7s are simply perfect for me. Again, I am coming from the EX51s. You can tell by looking at them that they are made of more or less the same material, black plastic, but the CK7s are more elongated with a longer taper so-to-speak. Size seems perfect, I can barely tell they are there! In contrast, the ER6is have a clear plastic, bi-fangled tip. I don't know how to describe them but they felt less comfortable to me. But both tips on the ER6is and CK7s felt better than the small tips on the EX51s.

Isolation

Of the three, I felt the CK7s isolate the best. Followed by the ER6is and then EX51s. Not much more to say. The CK7s isolate better than the EX51s. I could hear even less background nose while wearing them.

Sound

EX51: All bass? Not very good at that. Where are the mids and highs? What else can I say?
ER6i: The polar opposite of the EX51. Very good highs and mids, no bass. We both agree they sound "tinny" compared to the CK7s.
CK7: The best of the three. Bass is there like the EX51s, only clear and controlled and defined. Mids are there. Highs are far better than EX51 but not up there with the ER6i but the overall result is more pleasing than the ER6i.

I am not a sound pro, so I am afraid I cannot be more detailed than that without knowing more terminology.


In the end, my ER6i-owning co-worker said I could pat myself on the back for making the better purchase.

Anyone interested in the CK7s can buy them for $75.00 at AUDIOCUBES.

I have both, don't bother with the CK9. I feel the CK7 is actually superior at half the price. AT really messed up on the CK9 IMO.

am glad you enjoy them!
they are also my favorite at the moment.
so far i've always used the medium size tips, comfy and nice.
but
a few days ago i tried the big tips after reading about these babes in some thread here...
WOW!
much more prominent lower end!
and even better isolation!
(downside mircophonics-actually in my body noise like breathing- were also emphasised)

give it a shoot, i was surprised by the imense improvement!

Will have to fool with the other tips sometime. Thanks for the suggestion.

About how long does it take to break these puppies in?

i'm really surprised that the ck7 isolated better than the er6i

The ER6i isolates better provided you get a proper seal. I suspect that you guys aren't really getting the best seal possible.

There is really no way the CK7 should beat out the ER6i because the ER6i has deep insertion tips. You have to follow Ety's insertion instructions for best seal.

Well, I didn't read the instructions. Just stuck them in. The CK7s just fit better, were more comfortable, and seemed to isolate better. Even my co-worker said, "Wow those feel nice" when he put the CK7s on after having taken off the ER6is. I didn't ask him about isolation.

I have both the CK7 and T25 (Vibe). I really like both of 'em but I haven't had the chance to do any side by side comparison yet. I'm still waiting for my T25 to burn in a bit before I compare them directly.

You really can't go wrong with either one.

Am confused. T25 = V-Moda Vibe?
