“Bought the active noise cancelling version of these as a daily deal on Amazon for <$20. Active noise cancelling completely broken on both my original unit and the replacement - so on one hand the quality was horrific. That said, I really enjoy their overall sound - slightly warm, bass present but not overwhelming, polite treble. Shallow fit IEMs not designed for...” --DrikTheTroll
“ 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
“ First, I want to thank Phiaton for the review sample. As a headphone brand, Phiaton is relatively new to the scene. But as a company, it has a rather long history. Phiaton was setup by Cresyn Korea in 2008 as an initiative to launch its own high end headphone line. Up to that point, Cresyn has been very successful in the headphone OEM/ODM business all over the world, yet not quite known...” --ClieOS
“ 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
“ Fit and finish The PS200 fits well in my ear canals, although the body is on the large side. Because of this, they constantly push against my antitragus, making it sore after a while. However, I doubt this will happen to other users. Isolation is quite good; they isolate about as well as my ER6s, despite using single-flange tips. However, the tips are quite thick, and don't squish down quite...” --12345142
“ 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.
