I do not think that all earbuds from the same series sound similar since my AP8's left channel is louder than the right!
also,the fit is better than yuin series
it is the best earbud i have so far including yuin ok1,mx980,blox anv3 and mdr-e888! Danneq give pk1 a try and you won't regret it! The amp actually pump them up but without the amp it still sound great!
It is a good earbud for its price but there is no way it can compare with the original yuin pk1.one more thing, i talked to datsen before and he said he could make me a yuin pk1 modded for $70 but i decided to buy the original one!it is the best earbud i have so far including yuin ok1,mx980,blox anv3 and mdr-e888!

Soooo, I'm supposed to be taking a break from the computer. But, my DIY PK2 came in!
The sound definitely depends on the foams. Without any foams they sounded very odd indeed, with the stock foams it was better.. but I found the highs slightly muffled. Moved to some thinner foams from a pair of sansa stock buds and cut them into donut foams. These are the clear winners. I think differences in the foams could be attributed to some of the differences in impressions on these.
With the donut foams I am very impressed with the sound. They don't beat my portapros on sound, but they come closer than I believed they would. They certainly are more portable than the portapros!
These will be my new go-to portable set, replacing my portapros. I think I might try to order 4 more sets, 2 to give as gifts and 2 to keep as spares
TL;DR - If you have small ears and need a truly portable set of headphones.. This is definitely the best budget option, if not the best option period. Buy a set.
