I’ve got an Openrun Pro 2 after my Openrun Pro started getting a weird rattle after a few years of daily use. It leverages a little speaker tuned to be used just outside the ear more than bone conduction, but the app does let you go to a “classic” mode that relies on bone conduction more. Either way, I’m really happy with it. The one thing to keep in mind is that it has zero noise cancellation, so it’s pretty terrible in places like airplanes or when you mow the lawn.
