“ These were my first real earphones, and I bought them entirely because they'd been spreading like a plague on a forum I used. Upon first hearing them I was disappointed, but over time they grew on me, and until upgrading to the ER4, they were a firm favourite. Some of my friends couldn't get the fuss, nor understand why anybody would spend a hundred bucks on iPod earphones, but then again...” --BBBS
“ 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
“ First off let me preface by stating that I bought these on a whim. I had read many things about Etymotic's penchant for accurate reproduction. The initial impressions I got from these were a mixed bag. First off, I love the isolation factor, putting these on in the middle of a crowded communal area was like stepping into a library. I tried the various silicone...” --Exarch
“ I loved these buds to bits, they were the perfect everyday headphone. Small and light and comfortable and barely protruded past the outside of your ears. I like the fact that no one can really see them easily.. Very handy and they were well suited for running. I miss mine, unfortunately they broke when someone stepped on the cord whilst I was walking.. So sad about that still. ” --jcotteri

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.
“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
“ These were my first in-ears, and since owning them I've had the Ultimate Ears Triple Fi and the Klipsch Image S3s. I'll be comparing the ER6s to these. I remember the Etymotic's sound being very warm and natural, absolutely never harsh sounding. You could throw it the hissiest, most cymbal-laden music and it would sound wonderfully dark. It really had a...” --ledhed2222
“First impression, extreme clarity without being harsh, very bad cable design, people said ER4 lacking bass, either they are are lover of Aurisonics or they didn't get the insertion right with ER4s Even with P to S adaptor, still deliver great bass. fast, precise and great texture. And one of the deepest bass I've heard coming from BA driver. -Sound Overly compressed/brick wall record sound...” --darkinners
