“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
“ 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 recommend them to clean, i boiled them in water. ” --angevoi
“After starting to review a few IEM's in the past week I decided to slip these babies back into my ears as a reference point for the other IEM's. After doing so for a few minutes I realized these really needed a proper review as they definitely keep up with a lot of gear that is more expensive. As can be seen by the picture these are very tiny being the smallest IEM I have owned to...” --dweaver
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 cannot give you a price comparison or compare it to others in its price range as i was given these as a gift. but i loved these things. the bass was impressive, good highs, and smooth mids. although they tend to be a little unclear sometimes i find them to sound very enjoyable and stunning. they didn't distort or clip at all and i noticed no sibilance at all. the only thing i can complain...” --bcasey25raptor
