“ This "moving armature" descendant of the Ortofon e-Q7 makes no sacrifices in terms of quality, despite being introduced at a more affordable price point. The introduction of a new cord and strain relief system help tame microphonics and make the model easy to wear both down and over the ear. The all-aluminum housing is large and may not fit all ears, but the design is simple and...” --Dekimasu
“ These were my sweetest sounding head-gear yet. It would be brilliant all-rounder if it would not require a portable amp for portable use. This is the first reason i left it, otherwise i almost got an ear infection from those foams.., they get dirty in a few weeks of massive use.

Actually, I'm not really keen on the idea of using an IEM since they irritate my ears...” --lotusbloom
“ The PK3 is a great, warm earbud. It does vocals especially well because it is very mid-focused. It has impressive bass extension, not especially strong impact; the trebles are smooth and may roll off too soon for clarity and detail nuts. But the mids are what the PK3 are all about. ” --kmhaynes
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
PK2 earphones are the low impedance version of PK1. Although not as good as PK1, PK2's sound signature is similar to PK1. You don't have to drive PK2 with an expensive head-amp. If you are looking for something with high performance/price ratio, PK2 might be the best choice.
“ Well firstly this is not a true iem. The sound is about as great as one could get from an earbud. In my limited experience and without trying the pk1, I would say these are the finest buds you can buy. With that said, these are not for everyone, this is a niche product within an already niche market. I find driving it with my D12 anaconda makes for a pleasurable sound,...” --Jamesdeandoa
