FYI, for anyone in Southern California who wants to hear the Heir products, there is a Head-Fi meet on November 3rd, 2012 in San Diego, CA:
Brannan from Heir Audio USA will be attending and he will be bringing the 3.Ai's, 4.Ai's, and accessories to the meet. He has also offered to do ear impressions for free for anyone who shows a proof of purchase for any Heir customs.
If you are planning on attending, please post in the thread above. If you plan on having Brannan do ear impressions, definitely post in the thread or PM me so he will know how many people might want impressions done.
Hope some of you can make it to the meet.
