“Looking at the picture of the PK3's I wasn't expecting much. They look and feel cheap using a generic case for the drivers. First I tried them without the foam covers and they sounded awful. I originally thought I had been sold a pair of fakes but after using them with the full cover foams I am impressed. they have good definition and separation in the mid and high frequencies. The bass is...” --thebluebulk
“ 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
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.

I recommend them to clean, i boiled them in water. ” --angevoi
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
“ I was trying to be generous with this review, I had these for fewer than two hours because of the comfort, They ACTUALLY cut up my ear canals, there is no exaggeration, my ears bled, and I've never been a fan of foam tips. Foam tips get ripped up, and really feel insecure in my ears, plus the plastic tube can become exposed and creates a level of discomfort greater than that of the silicon...” --ffdpmaggot
