I was planning to post my review of them this week but stupidly made a promise to myself to finally finish up my HD25-1 review first, which I have yet to do.
For what they cost I really like the Cobys. Maybe I've simply become acclimated to crap SQ because of the Kanen and Panasonic headphones that I've reviewed recently, but I've been listening to the Cobys side-by-side with my AKGs and nicer Philips phones and they aren't offensive at all. They don't do anything amazingly well but the sound signature is quite balanced and coherent. They have fair extension on either end, good clarity, good instrumental separation, and so forth. I did A:B them with the KSC75 for my review and they differ quite a bit in what they do right. I'll just post part of that paragraph from my review in its unfinished state:
| The CV-185 sound less muddy at the low end but also lack the fullness, smoothness, and dimensionality of the KSC75s. They do boast better separation and a more emphasized midrange compared to the KSCs. With the foam pads they are also more balanced and neutral, with treble that lacks the bite and sparkle of the KSC75s but has more convincing tone. |
The foam pads in question are radioshack flat foam pads, courtesy of jant71. They change the signature of the Cobys quite drastically, reducing the bass impact of the stock pads (which isn't great to begin with) and bringing forward the treble (which is otherwise quite laid-back).
I don't really think these can compete with a properly-modded RX700 but they probably best the Flats in terms of overall usability. To the credit of the 'flats' their frequency response is pretty even while the Cobys have some spikes here and there. But while they aren't "giant killers" (hate that term) by any means, for what they cost ($10) they really do no wrong.
And yes, as far as I know the CV215 are just different color schemes. I actually do like the way these look. Thay are pretty large but yet very low-profile and understated so they don't draw any attention.
