“ This IEM is definitely the best bang for the buck! Basshead person should purchase it without a doubt. Even it's higher brother, Philips SHE9800 didn't able to match the sound quality of this IEM! :D It produced very deep punching bass and high definition clarity on mid and treble. It feels like you have your own built in sub-woofer inside this IEM! Comfort to use in a long run,...” --chrone
“ 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. 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

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.
“Got these on a sale, and was very pleasantly surprised. Originally, I was looking for something that isolates well and does not sound tiring for use in the office, but ended up using them as my first choice HP (instead of Alessandro MS1, Porta Pro, KSC55). I have been using them with uDac2, 2nd gen iPod nano, and Audigy 2 ZS. They are easily driven by any of these...” --gvz
“As for any 'flat EQ' speakers these IEMs lacks a bit of energy and sparkle (not definition, they have plenty of it!), not everything is rendered precisely since they try to do everything (in particular I do not like the rendition of cymbals), so they do not excel in any particular area except for soundstage (I noticed that it's a common problem with IEMs that try to expand the soundstage)....” --Tetsuro P12
