“ 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.

So its decent...” --vaibhavp

Cowon EK2 review, compared to Xioami Piston:- No, no formalities what so ever, No intros nothing, you are not here for intros And Add S to hits. Just to add that my piston has its filter and foam...” --suman134
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
“ 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.
