I don't think my ED3c are comfortable. But i haven't really listened much to them since i didn't like the sound.
The HDS1 is better than HDS3 to me, the HDS3 is lacking in clarity and highs compared to HDS1.
There are some positive reviews for HDS3 though, so you might want to try them anyway, since they cost $5 or so at gearbest...
I'm not sure where to find the best price from a reliable seller for the HDS1 now since gearbest don't have them anymore/right now.
you might want to check out joyroom e107 as well, i've read that they are small and comfortable
HDS1 is a good option.
@KcLKcL None of the ED3 variants are micro-drivers so they don't really fit the request. The only micro-drivers KZ currently makes are the HDS1/2/3. The rest are all 7mm and up or pair a micro 6mm with a larger driver (ZS1/2 and DT5 for example).
My micro-driver thread has a bunch of inexpensive options listed and could be helpful; http://www.head-fi.org/t/817426/micro-driver-madness-work-in-progress. I'd recommend the VJJB K2S. Highly overlooked little earphone around here imo.
Obviously those impressions are all from one person (me), so look around for more reviews/impressions if any of them are of interest. Will be updating with the E107, Remax 565i and some others when they eventually make their way to Canada.
