“ 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

“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
“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
“ I'll just go and rewrite this... Anyways, these would be my 2 year old IEMs that I still haven't managed to break. Pretty impressive considering how many times I've shoved them into jeans pockets. Anyways, onto the sound. They're a very aggressive sounding IEM, with an apparent spike in the mids and a slight spike in the bass. This makes it a fun listen though, without...” --Byakushiki

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 remember getting my first iPod in 2007, the 3rd generation nano. The earbuds that came with it stopped working when I left them in my pocket and washed them, so I ran out to Best Buy and picked up these since they were on sale. I actually still have them in almost the same condition, but nowadays I just use them as my occasional backups for my daily commute to school. But enough of that...” --theBjrd
“ 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
