I bought a TurtleBeach Audiotron years ago. It needed to hook up to the TurtleBeach server on powerup. Naturally, TurtleBeach turned that off at one point, bricking the Audiotron.

Fortunately, they did release a patch that bypassed the ping. I continued using it for years, and finally replaced it with a Grace Digital device, which also relies on connecting to Grace Digital on powerup. I know it'll eventually fail when GD moves on.
