“ Update: Reduced design rating due to ever-tangling cable. The cable is MADE with some type of built-in twisting/tangling design flaw. Just holding the headphones in my hand, the cable wants to twist and turn and due to its material, it's never fully "straightened out" like most other headphone cables. Due to this, it's become unusable. I've owned the original Bose IEs and now bought these...” --xx0xx
“ 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
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

“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
“ Really a horrible set of headphones for the money. I got these way back as an upgrade from stock ipod headphones and was blown away by the bass. At the time all I wanted was bass and boy did they deliver. At the time I loved them but as my music interests grew and expanded so did my realization that I had horrible headphones. Last year I picked up a set of AWEI ES-Q3 off...” --kitten wizard
