More opinions

My GF

Year ago, my GF compared PK1 and CM700 and choose CM700 as her earphones. She hated PK1 for its "unbearable bass". Now she compared CM700 and OK1 and found OK1 to be a better can:
OK1 sound is 3D, fuller, better balanced, a bit muffled but more detailed. OK1 conveys emotions better.
CM700 sounds flat, too ringing with very agressive highs.
Her only but important complain was "OK1 sounds underamped straight from iPod".

My daughter

She prefers PK1 to OK1. She confirms that OK1 is more refined, but she finds PK1s sound to be more pleasant. I asked her to evaluate the differencies step by step. The results are exactly the same as mine so I do not post them here. She gave the following descriptions:
PK1 - vocals are more neutral, forward, with long decay.
OK1 - vocals are slightly dry and distant, more detailed.
PK1 highs are stronger, OK1 are softer.
PK1 bass is deeper, OK1 is faster and tighter.
PK1 sound is reverberating, with longer decay, musical, pleasant, more integral.
OK1 sound is fast, analitical, detailed and precise.
