iOxmount

From Latch Lake:

In partnership with iOmounts, the iOxmount is a flexible and secure way to magnetically attach your phone or tablet to your microphone stand. Compatible with most portable devices of today and more importantly tomorrow. The mount is supplied with a smooth steel ball attachment (iOball) that screws onto any 5/8"-27 thread in place of the mic clip, a magnet (iOcore) which can be positioned anywhere on the outside of the ball, and two steel stickers (iOadapts), that you apply to your approved devices or their cases.
