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

“I had this earphones for 2 years and I must say, that I was really satisfied with it. With the possibility to change bass you can choose what really fits you and I must say, that the bass was really nice, clear and deep (I used the middle one). Only cons which I found are: hard cable - it can easily pull out the phones from your ear... size - the phones are little longer then most...” --Benik3
“ I used to own MEElecs. George Carlin said that he never was fine and dandy in same moment. I was. Now, I am sad to say that I was so careless to lose them in worst possible scenario. They were not in their pouch, in my backpack, but alone. In my pants pocket. With foolish illusion of safety. One moment they were in my jeans, next one they weren't, how- three months later...” --milan425
“ 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

“ 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
“ Introduction First, allow me to thank the great folks at MEElectronics for sending me a sample of the newly released M11P+ IEMs for review. Prior to sometime in early February, I wasn’t aware that MEElectronics existed. It wasn’t until I came across a review of their M9 IEMs on Head-Fi that I decided to check them out and the rest is history. MEElectronics IEMs have been some...” --TheGame21x
