“ These were my sweetest sounding head-gear yet. It would be brilliant all-rounder if it would not require a portable amp for portable 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.

“ In short: + Stylish looks + Comfortable + Powerful bass reproduction, flat but present mids, rolled off yet detailed and even sparkly highs, usually good separation + EQ-able +- "Dark" sound signature, tends to favor the bass and lower mids. Not perfectly analytical nor overly musical +- Best for pop and pop/rock - Lack of sub-bass detail, bass can be boomy - Impact not consistently...” --Shonen84
