Some users complained about the new Lightning-connected EarPods timing out, which would stop their in-line playback controls from working to adjust the volume, answer calls or use Siri. This update fixes the problem, making things just like they were when your phone had a headphone jack. Of course, you're probably beta testing iOS 10.1 already, looking forward to new features instead of stable builds with bugfixes . Either way, the current update should be accessible via your Settings menu now.
