I also had a listen to the ACS 5-way in-ear phones. Andy Shiach is a really nice guy with some previous history with M. It nearly resulted in some M branded in-ear phones. Shame that didn't happen.

Very impressive. Actually better than anything else I heard so I will be getting a pair in the near future. Another HH had the same experience. 3-D ear scan for perfect figment etc. Amazing SQ.
