As an AT Dealer and Avlex/MiPro Dealer, I can give experience on the AT892cW, HS-09 and HS-03.
I prefer the Avlex/MiPro HS-09 and HS-03 for secure fit and sound quality. I find them clearer than the AT892cW. The downside of the MiPro mics is the mini-coax connectors on the cables and adaptors. I have found that reinforcing the connection at the connector with gaff tape reduces/eliminates breakage. At $25.00 list each, cable breakage can become an issue.
