Auracast needs a broadcaster, and the documented broadcaster list is longer than people expect: a Galaxy phone (Quick Settings broadcast, with password and hearing-aid options), Samsung 2023 flagship TVs, and dedicated transmit hardware. The gate on every path is the same, per Google's own footnote: "Both the phone and headphones must support LE Audio." This page maps the transmitting side; our receivers page covers the listening side.
Figures on this page were checked September 2026. Every device claim links to a documented record on this site or a manufacturer page named in its row.
The broadcaster's role
Every Auracast stream has two sides. The receivers get the attention — earbuds, hearing aids, headphones joining a broadcast — but nothing to join exists until a device transmits. The Bluetooth SIG's overview frames the capability as one stream shared with many: the broadcaster sends, and nearby devices tune in, no pairing ceremony required. That division of labor is the whole architecture, and this page is about the first half of it.
Documented transmitters
The transmitter side is already documented across this site's device records; this section collects them in one table.
| Transmitter | What the record documents | Source / as of |
|---|---|---|
| Galaxy phone | Broadcast from Quick Settings in Media or Voice modes; broadcast password "to block unwanted guests"; "Allow hearing aids to connect" switch; renamed Audio Broadcast in One UI 8.5 | Samsung ANS10001042, 2026-09-23 |
| Android phone (Pixel and others) | LE Audio Auracast support on select devices; audio sharing to multiple headphones; QR-code handoff | Google blog + Android Help, 2026-09-24 |
| Samsung TV | "LE Audio capabilities to Samsung TVs with Auracast broadcast audio technology" — 2023 Neo QLED 8K and MICRO LED first, by software update; "a shared radio station" | Samsung Newsroom, 2026-09-24 |
| Dedicated transmit hardware | Source-agnostic boxes that put a line-level feed into a broadcast — the form factor venues and studios use; see the note below on capability claims | Category record, 2026-09-24 |
A note on that last row: this site documents dedicated transmitters as a category, and the call-to-action block on this page points at blafili's own Bicast unit. Its capability statements live in the product specifications we publish — this page keeps body claims to the manufacturer records cited above, so that block is where product specifics belong.
What it takes
Two requirements recur across every documented path, and both come from the sources above rather than from folklore.
LE Audio on both ends. Google's expansion footnote is the cleanest statement: "Both the phone and headphones must support LE Audio." Auracast broadcast rides the LE Audio stack — a classic-Bluetooth transmitter pair, the kind that has carried home-stereo links for a decade, is a different lane. Our codec pages cover the classic world; Auracast is not it.
The transmitter's own features vary. Samsung's phone broadcast carries modes and access control (Media versus Voice, passwords, the hearing-aid switch); the TV record is about software-updatable hardware tiers. Check the specific device's page — the Samsung phone record and TV record show how differently "transmitter" can be implemented at the detail level while resting on the same standard.
FAQ
See the questions above for the short forms; the practical summary: for home listening, the transmitter you already own — a recent Galaxy phone or a qualifying Samsung TV — may already broadcast. For a stereo or venue feed, the transmitter is a separate piece of hardware by design, because the source is a component system rather than a pocket device.

FAQ
The sending side of an Auracast broadcast: the device that puts one audio stream out for nearby receivers to join. The Bluetooth SIG's broadcast model splits the world into the device sharing audio and the devices listening — this page is about the sharing side.
Yes on documented hardware: Samsung's support page walks broadcasting a Galaxy phone's audio from Quick Settings, in Media or Voice modes, with a password option and a hearing-aid switch. Google's Android pages document the LE Audio requirements on the Android side.
Per Samsung's September 2023 announcement, its software update extended LE Audio capabilities to Samsung TVs with Auracast broadcast audio — starting with 2023 Neo QLED 8K and MICRO LED models — turning the TV into what Samsung called "a shared radio station."
Because Auracast rides the LE Audio stack, not classic Bluetooth. Google's expansion footnote states the requirement plainly: "Both the phone and headphones must support LE Audio." A classic-Bluetooth receiver, however good, is not an Auracast joiner.
