LE optimizes Bluetooth audio for extended play in headsets, earbuds, and other devices. ### Flexible, scalable audio architecture LE’s layered architecture unlocks premium Bluetooth audio experiences and solutions for consumers at every tier. ### Assistive listening devices re-imagined Accessibility features help turn everyday earbuds and headsets into reliable feature-rich assistive listening devices and hearing aids. ### Broad interoperability for max accessibility Interoperability with classic Bluetooth audio technology ensures backwards compatibility when consumers need it. ## State-of-the-art audio sharing Auracast™ broadcast audio is a quality-of-life upgrade; it’s also a life-changing feature set. It can be used to share playlists with friends and family, sync earbuds with TVs and PA systems in public venues, and more. Auracast enables the audio that matters most to be heard loud and clear. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-BenefitImage01?$QC_Responsive$&fmt=png-alpha) ## Multiple streams, multiple consumer benefits Multi-stream audio synchronizes audio streams to left- and right-ear channels for richer stereo playback. It also enables easy source switching between paired devices, including speakers and laptops, as well as more natural, seamless interactions with hands-free voice assistants. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-BenefitImage02?$QC_Responsive$&fmt=png-alpha) ## Low-power, scalable architecture The ultimate Bluetooth standard, LE supports premium audio feature differentiation and backwards compatibility across a wide range of platforms, devices, and tiers. And by definition, LE is significantly more energy efficient than other existing technologies. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-BenefitImage03?$QC_Responsive$&fmt=png-alpha) ## Deliver the experiences your customers expect ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-UseCase01?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Social listening experiences to remember A noise ordinance doesn’t have to stop the party. Whether consumers are living it up at a silent disco or killing time during a layover, it’s never been easier to share hot singles or playlists across multiple devices. Everyone hears the same music in sync, effortlessly. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-UseCase02?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Unprecedented control over audio Power is back in the hands of consumers with location-based audio control. A sports fan can sync up with the TV at the gym, so highlights come complete with play-by-play. A busy train terminal becomes easy to navigate, with announcements streaming direct to a traveler’s earbuds, in their preferred language (if multiple streams are available). ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-UseCase03?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Audio assistance that comes up clutch Spoiler alert: Movies have never sounded better. With LE Audio-enabled earbuds or hearing aids, a film buff with mild hearing loss can connect directly to a cinema’s Auracast™ stream for access to clear, synchronized audio. Full comprehension. Extraordinary accessibility. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-BTAuracast-04-UseCase04?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Seamless multi-device streaming Advanced multi‑stream capabilities change the equation for productivity, gaming, and hybrid work scenarios.
