Google's Wear OS documentation puts Bluetooth headphones on the watch itself: "You can use Bluetooth headphones to listen to audio from your watch," pairing them like any accessory through the watch's Bluetooth menu. The same article draws one hard line, "ANT+ accessories can't be paired with Wear OS watches," and splits the pairing steps by watch version. No codec list appears anywhere in it.

The pairing record
Among the device classes this site covers, the smartwatch has the cleanest Bluetooth audio story: the watch itself becomes the source, and Google's help article documents the pairing in a page that fits in one sitting. The record, compressed.

The watch becomes the source
The sentence that makes this page worth having is the audio one: headphones can take their audio straight from the watch. That is the phone-free run, the gym session with no handset in sight, documented as a first-party use case rather than a hack. Google scopes the pairing broadly, headphones and heart rate monitors in one sentence, and keeps one sensor family out entirely: the ANT+ line, excluded in the article's own "Important" note, is the anti-feature worth knowing before buying sensors for a watch-based setup.
The pairing itself is version-split, and Google says so in its own words: the steps differ by watch version. Current versions route through Connections in the settings; Wear 2 watches route through Connectivity. Either way, the connection gesture is the same, tapping the device's name when the watch's scan finds it.
The codec question, unanswered by design
The article documents pairing and playback and names no codecs. No SBC, no AAC, no maker names, which leaves the codec set to the same two-level answer the Android platform record documents: the SBC floor that every A2DP link carries, and the codec menu above it that each watch maker's build decides. For a wrist device the practical takeaway is modest expectations: the documented promise is playback from the watch, not high-bitrate audio, and our delay guide covers the latency side of any wireless listening.
What this means in practice
- Phone-free workouts: pair once through the watch's Bluetooth menu, and the headphones follow the watch; that is the documented setup.
- Sensor shopping: Bluetooth sensors are the documented lane; ANT+ accessories are excluded by Google's own note, so check the sensor's radio before buying.
- Older watches: expect the Connectivity menu instead of Connections on Wear 2 hardware, per the article's version split.
Headphones yes, heart rate monitors yes, ANT+ no, two menu paths by version, and no codec list anywhere. For a platform whose docs usually stop at generic pairing advice, Google's watch article is unusually complete, and it all fits on this page.
FAQ
Yes, and Google states the use case plainly: you can use Bluetooth headphones to listen to audio from your watch. That makes the watch a standalone music source, no phone required on the run.
Put the headphones in pairing mode per their manual, then on the watch: Settings, Connections, Bluetooth, Available devices on current versions, or Settings, Connectivity, Bluetooth, Available devices on Wear 2. Tap the headphone's name when the watch finds it.
No. The article's own "Important" note states that ANT+ accessories cannot be paired with Wear OS watches. Sensors that need ANT+ are out; Bluetooth accessories, including heart rate monitors, are the documented lane.
The article names no codecs, so there is nothing official to quote at the platform-docs level. Every A2DP link carries the SBC floor, and the codec above it is the maker's build decision, the same pattern the Android platform record documents.
