Auracast: What it is and why you should care

Auracast is one of the biggest upgrades to Bluetooth we’ve seen in years, yet most people still don’t know it exists—and that’s a problem. The feature launched in June 2022, but I’m still regularly asked, “What is Auracast?” Dozens of headphones, earbuds, and speakers already have it built in, and it could transform how we listen in public spaces. In particular, it removes the pairing step entirely and lets you “tune in” to a broadcast the same way you’d tune in to a radio station. The result is simple: easier sharing, better accessibility, and a genuinely new way to use personal audio.

Yet, despite its advantages, manufacturers barely talk about it. Some even bury the feature so deep in menus you’d never find it unless you were actively looking for it. If you’re buying audio gear in 2025—especially as a holiday gift—you should absolutely keep an eye out for Auracast compatibility.

What is Auracast?

Auracast is a Bluetooth LE Audio feature that lets many devices—earbuds, headphones, speakers, hearing aids, and even phones—connect to a single audio source without pairing.

In practice, this means you can walk up to a TV at the gym, a lecture hall microphone, a train station announcement system, or a friend’s phone and seamlessly tap into the audio. Our own testing with JBL and Sennheiser gear demonstrates how fast and frictionless the process feels. If you’ve ever struggled to share audio on a flight or tried to hear announcements over a noisy terminal, Auracast solves that.

Why Auracast matters in the real world

Auracast isn’t a niche tech demo—it’s genuinely useful. During testing with the JBL Tour One M3 and Sennheiser Momentum True Wireless 4, it was easy to instantly share audio with multiple people—no pairing, no Bluetooth handoffs, no codes. Likewise, if I’m watching a movie on a Samsung tablet running One UI 6.1+ during a long flight, everyone with a compatible device can join in.

Because Auracast supports long-range broadcasts (over 330 feet / ~100 meters), public venues can transmit announcements directly to your headphones. This has enormous accessibility implications. For example, people who are hard of hearing can receive cleaner, more intelligible speech. Similarly, you can receive only the announcements that matter in noisy environments—your airport gate, your station, or your classroom.

If your TV supports Auracast, each viewer can set their own volume or EQ adjustments on their device (especially useful for dialogue intelligibility) without affecting anyone else. Newer LG and Samsung models support this, and it’s a real game-changer.

Which companies actually support Auracast right now?

Here’s where things get messy. Auracast has been available for years, but you’d barely know it from the way companies talk about it.

Brands loudly supporting it

Models like the JBL Charge 6, Clip 5, PartyBox Stage 320, and Tour One M3 support Auracast. The Tour One M3 even ships with its own Auracast transmitter. JBL markets the feature more aggressively than anyone else.

The Sennheiser Momentum True Wireless 4 support Auracast, and Sennheiser has been one of the more transparent early adopters.

Brands supporting it… quietly

The Sony WH-1000XM5 and WH-1000XM6 now support “Audio Sharing”—Sony’s name for Auracast.

EarFun’s sub-$100 earbuds, like the Air Pro 4, include Auracast, and the company spent months troubleshooting compatibility with Qualcomm’s help. That shows small manufacturers can support the feature without massive resources.

If Auracast is so good, why aren’t companies promoting it?

There are likely four main reasons why companies aren’t shouting about Auracast.

1. Early technical challenges

JBL openly acknowledged that Auracast support was tricky in the early days. Bluetooth SIG provided a framework but not a full roadmap, leaving brands to figure out implementation details on their own. This caused issues for products like the JBL PartyBox, which only receives Auracast broadcasts from other JBL gear. JBL says over-the-air (OTA) updates will fix this.

2. Manufacturers fear limited consumer awareness

If most people don’t know about Auracast, marketing teams hesitate to expend resources promoting it. LG told The Verge that the feature’s relevance to TV buyers is “still emerging,” which is PR speak for “people aren’t searching for this yet.”

3. Companies prefer walled gardens

This might be the biggest reason. Auracast is brand-agnostic by design, which runs counter to the locked-down ecosystems many companies lean on: TCL’s new Z100 Dolby Flex Connect speaker requires a TCL 2025 QM-series TV. Likewise, Apple has mastered the art of keeping everything in-house. If AirPods supported Auracast tomorrow, adoption would skyrocket—but Apple hasn’t said a word about it. Open ecosystems don’t always align with corporate incentives.

4. Infrastructure is still developing

Venues need transmitters, staff training, and legal compliance to support Auracast properly. Adoption is slow but growing—universities, churches, and even the Sydney Opera House have begun rolling it out.

Why you should care about Auracast right now

Here’s the bottom line: Auracast is already built into many of the devices you own. TVs, earbuds, phones, speakers—you might already have an Auracast-capable setup without realizing it, and the benefits are huge. For example, multiple listeners can join your audio without sharing earbuds. Dialogue intelligibility improves for viewers who need it, and noisy environments become easier to navigate.

People who rely on hearing aids get a more inclusive experience, too. Public venues can offer a modern, wireless alternative to legacy assistive-listening systems, and transmitters cost under $100, so even older devices can join the ecosystem.

Manufacturers are optimistic about Auracast’s future. Henry Wong from Bluetooth SIG says the tech is gaining “strong momentum across the industry,” with more deployments and increasing manufacturer support every year. But consumers can’t value a feature they don’t know about. Until companies start promoting Auracast—and until more venues embrace it—the responsibility falls on early adopters and journalists to highlight its benefits. For my part, I believe it has the potential to change how we use personal audio in public and at home. The sooner people know about it, the sooner we all benefit.
