This is a list I created on the Garmin forums to track peoples real world experiences with wireless headphones and the new Garmin Forerunner 945. I’ve copied the info onto my personal website as the Garmin forums are due an upgrade, so using this as a backup! Please feel free to add your experiences to the forums to keep this table as up to date and accurate as possible.
