“Months ago I believed the JH13Pro Freqphase to have the most clarity when it came to Custom In-Ear Monitors, but I was properly blown away by the Hidition NT-6 Pro with its death-defying clarity and resolution. Introduction After spending a lot of time with my JH13Pro I decided to seek another CIEM to possibly challenge or even defeat it. After browsing the ever-beloved head-fi.org, I...” --VisceriousZERO

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.

PK2 earphones are the low impedance version of PK1. Although not as good as PK1, PK2's sound signature is similar to PK1. You don't have to drive PK2 with an expensive head-amp. If you are looking for something with high performance/price ratio, PK2 might be the best choice.
