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.

“ 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
“ Well firstly this is not a true iem. The sound is about as great as one could get from an earbud.

“ 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
