“ 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

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
