“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 making them easy to fake. (In fact my first pair were fake!) these earbuds sound GREAT! Especially considering the price ($44) I have a few pair of earbuds in this same and higher price range and these PK3's knock all of them out of the water. They have a flat sounding...” --thebluebulk
“ 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. I recommend them to clean, i boiled them in water. ” --angevoi
“ 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

“ I am one of the crazy guys with a bucket full of IEMs. I listen mostly to my beloved Cowon J3 because I can equalize most IEMs for a sound I like. I have an amp. Now I have the 012s, like I needed yet another in-ear! I purchased the black filters to swap with the installed green based on reviews I read but they're not really necessary but they do make a change. I'm going to make...” --drsamdc
“ Audeo Phonak PFE232 Let's start with comfort. I have an ear that doesn't work perfectly with the pfe232. This may be rare, but I get a lot of forward treble that is almost sibilant, but more "in your face" with instruments like cymbals. This is not normal, as I can tell it is too far unbalanced to be intended. The cymbals are so far forward I can't listen to...” --luisdent
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.
