Mine arrived about a week ago, these are my new favorite IEM's. I am running them with a Xduo XDO5 Bal and a Fiio BTR7. The clarity and sound quality are impressive. So glad a took the plunge and bought them. My Sennheiser IE80's just don't sound a good anymore. If you are on the fence about getting these, get off and make the move. You won't regret it.
