Google is bringing Auracast, its Bluetooth audio sharing technology, to more Pixel and Galaxy phones.

Auracast, a Bluetooth Low Energy (LE) technology first announced in March, enables a single audio source, such as a phone, to transmit a high-quality audio stream to a large number of Bluetooth receivers. Unlike standard Bluetooth's one-to-one connection, Auracast transforms a phone into a radio station for many listeners.

Google initially offered Auracast support for hearing aids with the Pixel 9 series six months prior. This included presets for hearing assistance. Last week, Google expanded Auracast compatibility to Sony headphones, joining the JBL Tour One M3, Samsung Galaxy Buds 3 Pro, and Sennheiser Accentum True Wireless on the list.

Phones capable of broadcasting audio via Auracast include the Google Pixel 8 series and later, the Samsung Galaxy S23, S24 and S25 series, plus the Galaxy Z Fold 5, Z Fold 6, and Z Fold 7. Some Xiaomi and Poco phones, not sold by U.S. carriers, also support Auracast.

Auracast could be useful in locations such as airports, museums, and train stations for public announcements. It also provides an alternative to sharing earbuds when listening to music with someone nearby.

Auracast lets users broadcast audio to a friend's headphones, earbuds, or hearing aid if compatible. People can share their audio with others who have compatible Bluetooth devices. Joining a broadcast requires scanning a QR code or using Google's Fast Pair with their phones.

Although currently limited to specific phones and Bluetooth devices with Auracast, the technology shows potential.
