Google scopes Chromecast Bluetooth audio to two form factors, Chromecast with Google TV and Google TV Streamer (4K), and gives them the same rule as Google TV: several devices pair, one audio device connects at a time. The Chromecast-specific extra is Fast Pair, Google's quick-pairing lane for compatible headphones, which ties the accessory to your Google Account and reconnects without a menu walk. Google's article names no codecs.

Which devices this covers
Google's article on Chromecast Bluetooth audio is titled "Connect Bluetooth devices to Google streaming devices", and its first sentence does the scoping: the instructions apply to Chromecast with Google TV and Google TV Streamer (4K), the two streaming form factors that run the Google TV interface. That scope line is worth keeping in view, because "Chromecast" has meant several products over the years; this page stays inside the two Google names.

Fast Pair, in Google's words
Fast Pair is the part of the article that belongs to Chromecast rather than to the generic Google TV page. Google qualifies it first: "Fast Pair only applies to compatible devices like certain headphones." For those, the flow compresses to putting the accessory in pairing mode and selecting Connect when it shows up.
The account tie-in is what makes the lane interesting. After the first pairing, Google writes that a Fast Pair-enabled accessory "automatically detects and connects to your streaming device," and that Fast Pair "also associates your Bluetooth accessory with your Google Account." The practical result Google describes is a set of headphones that follow you: pair them to your other devices easily, switch between devices, and see a notification automatically when a previously paired accessory detects a compatible one. Pixel Buds get their own pointer in the article, to dedicated Help Center pairing instructions.
Where Chromecast sits
The connection rules here are the Google TV Bluetooth rules, and the one-audio-device sentence appears word for word in both articles; the difference is the hardware shortcut on the Streamer and the Fast Pair lane, which Google documents on the Chromecast side of its help center. Fast Pair itself is a phone-ecosystem feature first, and the Android platform record documents the codec stack underneath. For the other house's streaming box, the Apple TV page documents a two-listener feature instead of a fast-pairing lane, a genuinely different answer to the same living-room question.
What this means in practice
- Small rooms and dorms: a streamer plus Bluetooth headphones is a documented, supported combination within the two scoped form factors.
- Headphones that travel: with Fast Pair's account association, the same earbuds pair to the streamer and your phone without redoing discovery each time.
- Two people, one streamer: the one-audio-device rule applies, so the second listener waits for the slot rather than joining.
- Codec expectations: Google names no codecs for these devices, so set expectations by the SBC floor and the headphone maker's documentation, with our delay guide covering the lip-sync side.
On the Google TV Streamer, pairing mode is a physical act: hold the button at the back for 5 to 10 seconds and watch for the on-screen confirmation. It is the fastest documented route into pairing when the menus are not cooperating.
FAQ
Google's help article scopes Bluetooth audio pairing to Chromecast with Google TV and Google TV Streamer (4K), the two form factors that run the Google TV interface. Those connect to Bluetooth headphones and speakers with the usual pairing flow, plus Fast Pair for compatible accessories.
It shortens pairing for compatible headphones: put the accessory in pairing mode, select Connect when it appears, and after the first pairing the accessory detects the streamer and connects automatically. Google also ties it to your account, so the accessory pairs to your other devices and switches between them.
One. The article's opening lines set both facts: the first sentence lists the supported form factors, and the third sets the limit, so you can pair several devices but you can only connect one audio device at a time.
On the Google TV Streamer, Google documents a hardware shortcut: press and hold the button at the back for 5 to 10 seconds, and a confirmation message appears on screen once pairing mode is active.
