“ As of 2013, I could only find one pair of these on the internet. It's a shame because from my experience, cheap earbuds are oriented around the muffled bass emphasis and exhausting higher mid ranges. I myself came from the Audio Technica a900x and Bose IE2's which sound darker compared to these $10 earbuds. I love rich vocals and acoustic...” --Nec3
“ 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

“ 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
