+1. I can't find any mention of them anywhere. How about a link?
To be honest that says more about the Bose than the Cobys. We all know what the acronym stands for, anyway...
Regarding reviews, there are a bunch of reviews of full-size bose cans on the full-size forum and one or two reviews of the IEMs. Problem is that these are usually done by new members with no real point of reference as seasoned head-fiers don't usually bother with Bose. You can see the same trend now with the Bowers&Wilkins P5 in Skylab's review thread - a couple of new members are vehemently defending the P5s against all criticism despite not making their reference point clear.
I've heard all of the headphones in Bose's current lineup and was even lucky enough to try them with my own source/tracklist as the equalized demo stand at the 'Bose Boutique' I went to was partly out of comission. It's amazing how well they pick tracks that showcase the so-called strengths of their headphones while downplaying the weaknesses for the demo stand. The Bose IEs really broke down when I threw Change of Seasons at them. Very poorly separated sound; I wouldn't pay more than $30 for it. The headphones aren't actually that bad for a colored and bottom-heavy signatrure but I have no use for ANC and thus no interest in paying a premium for it.
