The EarPods that come with most new Apple devices already work pretty well, even if they aren’t the best option out there. But a new patent reveals how Apple could up its earbud game with a new wireless headset.
The patent, which focuses on improving voice quality for a “wireless headset with untethered earbuds” was filed back in 2014 and published by the U.S. patent office on Thursday. It details how these futuristic EarPods could pack multiple microphones in each ear, making it possible to carry out a call without picking up your iPhone. These microphones could also work together to deliver the best possible audio while cutting out other disruptive noises.
Each bud might also transmit sound over bone conduction rather than traditional speakers, similar to the original Google Glass headset and other Bluetooth earpieces. The patent also hints at a built-in accelerometer, a battery and a processor.
Of course there’s no guarantee Apple will actually release a pair of wireless EarPods. That does seem to be the direction where Bluetooth headsets are eventually heading though, and Cupertino likely doesn’t want to fall too far behind.
