“ 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
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

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
“Just want to state up front my review rating is an absolute rating, not one based on comparative performance, pricing etc. These are my observations after using an iBasso DX50, MacBook air, FiiO E17 and Sansa Clip Zip as test sources. I found very little variation between those sources with the DX50 maybe bringing out a little bit more richness and depth. Highs: Well what can I...” --Krisman
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
