“Remember those essays you had to write in grade school? Well I do even if you don't. In honor of that memory, I am going to write: What does the EarSonics SM3 mean to me? Back in March I was going to order the EarSonics SM3 based off the few things I have read about them, even though it wasn't much. But then something stopped me. Could they really be that good, and the shipping cost was as...” --average_joe
“http://www.earsonics.com/SM3%20engl.htm v2 page. Aside from the cable and new body, my impressions match what I had in my v1 review. http://www.head-fi.org/products/earsonics-sm3-universal-fit-iem/reviews/4422 Otherwise, these sound about the same as v1/the new ear-piece body shape is a lot more ergonomic(seems to be a bit smaller as well, but not as easy to get a good seal... At the same...” --svyr
“THE RATINGS: Highs: 4.5/5 Mids: 5/5 Lows: 4.5/5 (probably would be 5/5 with amping) Bass: 5/5 (swooshy style, though) Value: 5/5 Soundstaging: 5/5 This is all to say that the Earsonics SM64s are perhaps the best IEMs I have ever heard, and I was always a big IEM person. Let's be short about this: It absolutely slaughters the Shure SE530, SE535 line...” --Pepper
“ The PK3 is a great, warm earbud. It does vocals especially well because it is very mid-focused. It has impressive bass extension, not especially strong impact; the trebles are smooth and may roll off too soon for clarity and detail nuts. But the mids are what the PK3 are all about. ” --kmhaynes
“ 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 Im not a pro, please dont quote me if anything is wrong. The sound is one of a kind for BA, bass heavy sound signature. These are some of the bassiest BA you can find, with good instrument separation and soundstage. IMO really good for metal music, vocals are a bit far, v shape frequency responds. Build quality for the earphone body is just fine, but cable and tips have lots of...” --10shot9miss
“ 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
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch

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.
