After the debate around the pk2 review, I am considering about organizing a pk2 (maybe also pk1) free-to-try tour. I plan to send out 1 or 2 pairs of pk2 earplugs to those fellas who might be suspicious but still curious about this little thing. After you try it in your system, you can tell us your opinion loud and clear, no matter what you think about this earphone. In this way, it will be no bias since no money or benefit really involved.

Before I really do it, First of all, modd, please let me know whether this plan will break any rule of our forum or I step on somebody’s toe without knowing it.Then, I am also curious about how many of you are really interested to get it a try. So please reply or PM me if you wanna join, and also please let me if you have some though about it.

If everything goes fine with our foruma and some of you are willing to try, I will plan how we can get it done and post it later.

Cords broken is coverrd by waranty. HONGKONG dealer www.headphonehk.com is not authorized by YUIN and their PK earphones was not directly from us. We will not help them do any waranty and that is why their customer complaining. The post in HEADFI sponsor forum is by YUIN itself. We will do fast and convience waranty for sure.

We will do a free loan for ATH-CM7 owner in USA. Time is 2 month and hope to do comparing. Headfiers can post in this thread and apply.

Actually my dad is suitable because he although though he loves good sound quality for his classical music, he hates my full sized odd shaped headphones, and thinks IEMS are too much of a hassle!

This is my attempt at the Thaksgiving gift....

I have tried 4 different IEM's...often good quality sound but my ears produce too much wax (sorry for that visual)...and in the end I just get scared to put them in worrying about what will be on them when I take them out

I also own big closed earphones - but my son is constantly embarrassed when he sees me wearing them.

I cannot play music on speakers, becasue we pretty much do not have any speakers (my wife cannot find any to match the family room decor!)

So...in order for me to get my music fix when and where I need it, I would leave a pair of traditional earphones that do not look conspicuous and yet give me some isolation from the outside world.

Thanks.....

Well, I am currently on a long search for the best earbud available because I like to have the best sound possible in the smallest available package! I currently own just about all of the top of the line earbuds available, (Bose IE, B&O A8, Sennheiser MX-90, MX-500, V-Moda Remix) all in the $50-$100 range. At this point, I am most impressed with the Bose for their wonderful handling of low frequencies, and I would like to see how the YUIN's Stack up against their competition. If you send me a pair, I promise to do a through review and comparision on this forum and let everyone know about the quality of the product. Because I have heard just about all of the competion, I believe that I can give you some good feedback! Thanks!

Swagga,

I have the PK1 and waiting for my PK2 as well.

If Nanaki won't be able to send you one, I can send you mine and you send me your BOSE IE to experiment as well

I wish I had the chance to test the ATH CM700ti.

Cheers!
