“ EXECUTIVE SUMMARY 1. Not coherent throughout the audio band: a. Overall neutral, but but but b. What’s up with the peaks in the upper mids/lower treble?* c. Little bit bloated in the bass d. Bass not keeping up with the mids/treble 2. Little bullet design = comfort/fit that blows monkey chucks 3. ...” --purrin
“ 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.

I recommend them to clean, i boiled them in water. ” --angevoi
“After starting to review a few IEM's in the past week I decided to slip these babies back into my ears as a reference point for the other IEM's. After doing so for a few minutes I realized these really needed a proper review as they definitely keep up with a lot of gear that is more expensive. As can be seen by the picture these are very tiny being the smallest IEM I have owned to...” --dweaver
