Well finally got my pair of vibes after 2 weeks of post from US.
Using an iAudio U3 with and without penguin amp.
First off, there small, light and sit quite deep in the ear but are very comfortable straight off, no fiddling required.
Sound is strange, very deep bass for sure but it hits you but in a nice way. I listen to dance music and it gets to ya bones. After 12hrs of running in, the upper range still leaves a lot to be desired, highs are tinny and lacks musicality at any higher frequency. Seemingly devoid of air or seperation, generally they dissapoint.
I compared these to the CK7, i like the 7's for its natural sound, seperation, musical bass and a wonderfull sense of involvement. The vibes cant even come close to the CK7 on anything other than bass, the CK7's lack a deep bass feeling unless you slightly press the buds into the canal, then they come alive and have a deep musical bass, which along with its natural seperation, sound sublime. Only downside to them are short port tube and weight, they do creep out of your ears.
If only AT had made the things with a slightly longer port tube, i reckon the CK7 would the nuts and we would all be raving about them.
Anyway, the Vibes are good for bass, comfort and little else far as i can see. Shame.
Now to qualify my comments by saying that i think i may have a duff pair as i have to pull the headphone jack out slightly for them to sound 'normal', when fully inserted, the sound is horrible, all muffled and not right at all.Edit: It seems clear that my units are faulty, so take my comments on the sound quality of the vibes with a huge pinch of salt. Will report back on my new pair.
ps, think i might try mate the port of the vibes to body of the CK7's, anybody know how the Vibes come appart?
