1. An earbud, comprising:
a locator configured to:
determine a location of the earbud as one of a plurality of locations comprising in-ear and out-of-ear locations based on a comparison of features extracted from an acoustical sample taken by the earbud to features extracted from in-ear and out-of-ear acoustical samples; and
indicate the determined location in a location signal transmitted to a host device communicatively connected to the earbud.
