“Before writing this review, I would like to thank Charles for generously sending out multiple IEMs and amplifiers for us to try and review. Charles is also one of the friendliest and most responsive guys that I have met in the audio world and often responds to emails in a few minutes. This is something that I take into account when buying any product, especially one at this price. I am in no...” --lin0003
“ 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.

Hi guys, after spending some time with the new IEM from Rhapsodio, I thought I would post a more formal review of my experience with the IEM. So for those who have been interested or curious about Rhapsodio, hopefully this will shed some light on what they’re all about! ...” --Cotnijoe
“ 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
“Who/what? I'd like to thank Rhapsodio for sending the 2v1 our way for a tour, along with the Shozy amp. Australia isn't exactly a hot electronics place First off - Rhapsodio is a young IEM company from HK. They sell Custom and Universal IEMs and lots of cables, and some DIY amps. You can read more on their site and Facebook While I haven't bought their products yet and only tried their...” --svyr
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.
