I nabbed the ZSNs as a "I want to try out IEMs, see if they work better for me than earbuds, and I might as well get a pair that might even sound pretty good too" experiment. Had no complaints about them, though while I didn't find the treble annoying it did feel kinda' like it was compensating for having stretched not-quite-enough-treble to cover everything. Like the audio equivalent of someone relying a bit too hard on Photoshop's sharpen tool to compensate for a slightly blurry image. By the time my ZSN arrived the CCA C10 reviews were rolling in and I ended up getting that and being similarly satisfied with a similar opinion. The ZS7s were tempting, but they were a bit over twice the cost of the C10s and since the ZSNs were "good enough" for me I decided to go for the cheaper of the options. Still, for what I paid for the ZSNs they are awesome and and I've no real regrets for having gotten them.Holy Heaven!
I've just received a pair of 2nd generation KZ ZSN and I can totally say that the KZ ZS7 are better, noticeable better. The KZ ZSN have even slightly annoying highs/treble. I've bought them as a gift to a friend and also because they are so famous here and wanted to try them out, but I'm glad I purchased for myself the KZ ZS7 because I can say there's a clear big difference between the two. If you can go for the KZ ZS7, just go for them. The ZSN have the professional look and quality, may be they are more ergonomic and comfortable for some people, but in terms of sound I just got a little upset. I was expecting a very similar sound quality to the KZ7, almost unnoticeable difference; sad but true, they sound worse.
