I found this one review so far (translation by google)

They look interesting for $25, right around the MX500 price really. I might go for a pair.

Myself was □have listened in the earphone everybody □□PK3 ear plug. (□bright; This □listens is returns □-like □listens. Namely the ear plug after □listens □to tie; Must □return □YUIN Corporation. □□on; The merchant □has recycled the cost which the ear plug pays □□to be bigger than lives □the cost. But because this □may prevent delivers □the ear plug but actually □; Moreover □a person □□□way is advantageous to □□fair ~~ recommends each big ear plug merchant use.)

5: □□: PK3 □□the table □, does not wear a set of sentiment □under; The analysis strength may compare ~ with □time of price other □physical appearance

□□: PK3 in □□on, □and above 7k the superelevation □has hollowly in the 1k center, in is low □on has the promotion. But the peak valley □the scope is not very big. □□; □is compared to □the balance. (Is using mp3 □; I am ordinary □enhance 3dB in 1k)



Pushes □the nature and other:
1: The PK3 bass □thrust force depends on □□is smaller than; Even if 推力比 □the small □body listens also to be able to push □6~7 to become ~~

2: The PK3 center high □chord □□thrust force request is very high! ! Is insufficient in the thrust force on machine; □the sound □dry feeling □is especially bright □. In □□□stands □embraces; PK3 □the sound flat abundant □were many.

3: The machine matches: PK3 is joined to □mellow "□the core" mp3 □. Is joined to the thrust force also also to have compared to □big rectangular strength chip mp3 the is not vulgar table □.

With □recommends: □the outlook is not □heavy □, is happy □listens to ROCK, the POP friend.

Thanks!

Based on how much I am enjoying the PK1 and the PK2, I can't wait to hear the PK3 for their value (quality / price). I just placed an order at the very desirable Group buy price. I'm especially interested in how these stack up against the Koss KSC75 - my currently favorite $25-ish headphone, and the Sony EX71-SL a long-time family favorite (for when my kids come to me looking for a portable headphone) in the $30-ish range. Based on the value offered by the PK2 and PK1, my expectations are pretty high for the PK3. When the PK3 get here, I'll find out.

 

[ClixCrisis]

Ack, placed an order. Will I get a confirmation or anything?

Can someone explain to me the difference between a group buy and a regular buy? I placed an order for only one under "group buy"... I have a feeling that was incorrect o.o;

group buy means it's an offer for a group(in this case head-fi members) to purchase for a lower price because of the quantity of the order. you don't have to buy more than one yourself
