YUIN earphones free-to-try tour

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.

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.
