Hello, SENNHEISER IE7 IN-EAR EARPHONES HEADPHONES EARBUDS - eBay (item 110388735390 end time May-17-09 16:00:00 PDT) What does it look like?

Some people says that OK3 is better than PK2. Is it true?

Denon C551 is better? I heard that RE2 is quality/performance leader. A lot of people think that RE2 is better than Westone UM1. Also i think PK2 is the leader of earbuds. (unamped) Isolation is not important for me. But i want realistic sound. I can't decide which one to buy.

Thanks. Any other comment?

Which one is better? Yuin PK2 or Head-Direct RE2? (unamped.)Isolation is not an issue and also i like analytical sound with recognizable bass. Not boomy but recognizable.

Do anyone compare PK2 vs OK3(as earbud)?Which one is better,i can't make decision.

Thanks for answering. I'm curious about the sound quality of OK3.Fang said, if you use it as earbud,OK3 is a bit better than PK2.Their prices are relatively same.Any comparison about their sound quality? Edit:I searched links but i couldn't find any comparison between OK3 and PK2

Do anyone compare PK2 vs OK3(as earbud)?Which one is better regarding sq, can't make decision.

Hi all, As an earbud would you recommend OK3 or PK2?In addition to this I wonder which earbud is the best earbud on earth(with no amp)?(regarding senn. mx series,yuin pk,ok series,audio technica ath cm700 and other earbuds) Thanks in advance.
