“ 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
“should have added a cable clip , fitting is awesome , sound quality is just what i like , bass is fast , hits with a punch , really nice mids , highs are lively too . thick and dark signature , my fav sig . secoend in command of my line up , might let the xba-3 creep in between , but xba-3 lacks sound stage , come on xba-3 , being a $200 phone you can not lack sound stage . but xba sounds fine...” --suman134
“ Got these at Amazon after a long search and much reading. Sound for the price is really good. Not in the same league with my Sony Pros or the Sennheisers but surprisingly close.

“ 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
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
