Heir Audio 10.0 Universal IEM - this is used but in great condition. I have ultimately decided to go with an IEM nearly 3x the cost of the Heir, (QDC VX), and I view the Heir as one of the greatest bargains in high end IEM. The tuning is great and definitely can sit at the same table as summit-fi IEMs. I thought the Heir 8.0 was good, but this was a different level. Split shipping, PP fee. I am also selling an incredible like new pair of Campfire Solaris IEMs. See link in my signature, so check out both if interested.
