“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
“Looking at the picture of the PK3's I wasn't expecting much. They look and feel cheap using a generic case for the drivers. First I tried them without the foam covers and they sounded awful.

They fit without touching most of your ear and can be worn cable up or down. The barrel is relatively long so it will...” --grahamnp
“ 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
