“Audio Quality The bass is pretty awesome. Full rich controlled clear deep bass. Usually bass heavy earphones tends to cover up the mids and highs. This one performed well. Love the tuning bass ports customization which is similar to XePort 5010-8 and MEElectronics SP51. Isolation Surprisingly good overall soundstage coming from such a bass-heavy earphones. Though its...” --unbornchaos
“ 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

“ 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
