Bluetooth 6.0, released in late 2024, is being hailed as a major upgrade for wireless audio, offering faster connections, lower latency and precise device tracking—though most headphones have yet to adopt it.
The Bluetooth Special Interest Group (SIG) released the Bluetooth 6.0 core specification in September 2024. The new standard introduces features aimed at improving connectivity, efficiency and real-time performance across devices.
While some newer smartphones already support Bluetooth 6, most headphones and earbuds continue to rely on Bluetooth 5.3 or 5.4, slowing widespread adoption in the audio market.
Bluetooth is not just about going wireless. Each new version affects audio compression, transmission quality, latency and connection stability.
As wireless listening expands into gaming, AR and VR, improvements in Bluetooth technology play a critical role in delivering smoother and more reliable audio experiences.
Improved connection efficiency
Bluetooth 6 enhances how devices discover and pair with each other. This results in faster, smoother pairing and more reliable reconnections.
The update is especially important for Bluetooth multipoint users, who often experience glitches when switching between devices like phones, laptops or tablets.
Bluetooth 6 introduces Decision-Based Advertising Filtering and Monitoring Advertisers, which improve interoperability and enable quicker reconnections to previously paired devices.
Smarter Low-Power Pairing
In Bluetooth terminology, “advertising” refers to how devices broadcast their presence within a network. Bluetooth 6 improves this process by allowing headphones to send smaller, low-power signals.
This enables instant pairing while using less battery power. However, both the audio device and the smartphone must support Bluetooth 6.0 or newer to benefit.
Smartphones lead adoption
Many smartphones released in 2025, including Google’s Pixel 10 lineup and Apple’s iPhone 17 family, already feature Bluetooth 6.
Headphone manufacturers, however, have been slower to adopt the new standard. Wider availability of Bluetooth 6 audio products is expected in 2026.
Older Bluetooth versions often struggled with audio and video synchronization. While recent updates reduced this issue, Bluetooth 6 goes further to support evolving use cases.
The new standard improves the Isochronous Adaptation Layer (ISOAL), which handles real-time data such as audio, enabling faster transmission and larger data transfers.
What this means for Gaming, AR
Lower latency could eliminate the need for wired headphones during mobile gaming. Console and PC gamers may also find that everyday Bluetooth headphones can meet the demands of single-player gaming.
As AR and VR experiences grow, these latency improvements become increasingly important.
Universal device tracking takes shape
One of Bluetooth 6’s most anticipated features is Bluetooth Channel Sounding. It offers centimeter-level precision for locating devices without requiring ultra-wideband (UWB) chips.
UWB chips provide accurate tracking but are costly and complex to integrate. While products like Apple’s AirPods include UWB, most headphones do not.
Channel Sounding uses Phase-based Ranging (PBR) and Round-trip Time (RTT) technologies over Bluetooth Low Energy, reducing the need for UWB hardware.
Cross-brand device finding
With Bluetooth 6, a smartphone from one brand could locate earbuds from another, as long as both support the standard.
Although few mainstream headphones in the US currently offer Bluetooth 6, broader adoption is expected in 2026.
The adoption gap is clear. The iPhone 17 supports Bluetooth 6, but the AirPods Pro 3 still rely on Bluetooth 5.4.
Apple continues to prioritize proprietary wireless technologies, while Google has pushed broader adoption of Bluetooth features such as Auracast.
Earlier this year, Google expanded Bluetooth Auracast support across more Android phones, headphones, earbuds and hearing aids.
Auracast allows users to share audio with nearby supported devices, making Android phones the easiest way to experience Bluetooth’s latest innovations, particularly in the US.
