Apple is taking a major step beyond Bluetooth with a brand-new wireless protocol called Spatial Relay Audio-Visual Sync (SPR AVS), launched alongside the iPhone 17 series. This innovation aims to deliver lossless audio and near-instant responsiveness across Apple’s ecosystem of devices.
According to reports, SPR AVS keeps latency under 10 milliseconds, making it suitable for latency-sensitive use cases like gaming, music production, and video editing, areas where Bluetooth has long struggled. The protocol can also dynamically adjust bandwidth based on environmental noise and device conditions to ensure a consistent and stable signal.
Going beyond pure audio transmission, SPR AVS can also handle biometric and sensor data, enabling tighter integration with features like Spatial Audio, as well as future AR and VR applications. Another highlight is multi-device sync, which keeps playback aligned across devices like AirPods, iPhones, and Apple Vision Pro.
Apple has been laying the groundwork for this shift. Earlier this year, the AirPods Max added 24-bit/48kHz playback via USB-C, though Bluetooth compression still limited wireless listening. With SPR AVS, Apple is closing that gap by bringing wired-quality playback to wireless audio for the first time.
While Bluetooth will continue to be supported for universal compatibility, SPR AVS makes clear Apple’s intention to build a more advanced in-house wireless standard. Initial support begins with the iPhone 17 series, AirPods Pro 3, and Vision Pro, with future expansion expected to Macs and upcoming AirPods models.
If broadly adopted, SPR AVS could redefine the baseline for wireless audio performance, potentially pushing rival brands to rethink their own approach to high-fidelity, low-latency sound.
