“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. First I tried them without the foam covers and they sounded awful. I originally thought I had been sold a pair of fakes but after using them with the full cover foams I am impressed. they have good definition and separation in the mid and high frequencies. The bass is...” --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
“should have added a cable clip , fitting is awesome , sound quality is just what i like , bass is fast , hits with a punch , really nice mids , highs are lively too . thick and dark signature , my fav sig . secoend in command of my line up , might let the xba-3 creep in between , but xba-3 lacks sound stage , come on xba-3 , being a $200 phone you can not lack sound stage . but xba sounds fine...” --suman134
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.
Technical Details * Impedance:32 ohm(at 1KHz) * Frequency response: 20-20,000Hz * Sensitivity:120 dB (at 1KHz) * Max Input Power: 400 mv
“This is my first review so keep that in mind. I bought a pair used UE 900's at Cex, an electronics resale store in San Francisco. I was cleaning them and pulled the wrong way on the MMCX connector and the freakin' right unit came apart and ripped the internal wires apart. I contacted Logitech tech support and was shipped a complete UE 900s for a replacement! They were quick and helpful...” --caffed
“I decided to purchase the new model UE 900s instead of the UE 900 because of some build quality changed and added accessories. Here is a review of what I received. Packaging - The packaging is very nice and they fit a lot into the fairly small box. Everything is quite elegant looking Accessories - There are tons of accessories. There are many sizes of silicon and foam...” --Got the Shakes

“ 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
