Pros: The full frequency range is there, with nothing missing, according to my ears
Cons: Bulkiness (but then there are 12 BA drivers per side), Cost (but then if they are the best)
I have to say, when I first saw them, 12 bands per driver! Isn't that a bit over the top? But after listening to a demoed pair for just 5 mins with my iPod, I bought a pair, they are really that good! I got the AKR03 version though, not sure if they are the same as the JH Audio version.
