Bose has introduced Bluetooth LE Audio and Auracast functionality to its flagship QuietComfort Ultra Headphones Gen 2 through a firmware update, establishing the brand’s presence in the emerging audio-sharing ecosystem. The update, labeled version 10.12.12, has been rolling out gradually in recent weeks and represents a significant moment for Auracast adoption given Bose’s standing in the consumer headphones market.
Auracast technology enables a single device to broadcast audio simultaneously to multiple compatible headphones and speakers, with potential applications ranging from airport announcements and live venue performances to educational settings and home entertainment. The technology can also support accessibility features such as enhanced hearing assistance. Since its official announcement in 2022, adoption has progressed gradually across the industry, with support currently limited to select manufacturers and specific product lines.
Prior to Bose’s involvement, companies including Sony, JBL, Samsung, and Sennheiser had incorporated Auracast into their audio devices, alongside smaller manufacturers such as EarFun. Sennheiser also released a dedicated Auracast transmitter during this period. The expansion of the technology into Bose products is expected to accelerate mainstream awareness and adoption.
Beyond Auracast functionality, the firmware update also enhances audio performance over wired USB connections with improved balance controls for gaming and chat applications, alongside better compatibility with web conferencing platforms. A Bose representative indicated that the company’s standard QC Headphones Gen 2 model is scheduled to receive the beta firmware in the coming period.
