引句：
Smart ear devices, or "hearables," are the new horizon in the wearable space and for good reason.

Alternatively, ear devices have the potential to make a lasting impact in the wearable space.

And finally, getting back to the ear, LeBoeuf said we may someday soon have "hearables": in-ear devices that provide private, intelligent communication along with super-accurate biometric measurements.
