Bluetooth 6.0 is the 2024 core specification release headlined by Channel Sounding, a distance-awareness feature, alongside advertising and link-layer refinements, and it changes no audio codec. The core line has since moved to 6.1 (adopted April 2025) and 6.2 (adopted November 2025), and current flagships quote 6.0-class radios in their spec sheets.

What 6.0 introduced
The specification document's own list of the 6.0 feature areas is the honest checklist, and all six names below come from the acknowledgments section of the Core 6.0 document itself.
| Feature | Domain | Source / as of |
|---|---|---|
| Decision-Based Advertising Filtering | Advertising efficiency: devices skip advertising channels where nothing useful is being scanned | Core Specification 6.0 acknowledgments, 2026-10-13 |
| Channel Sounding | Distance awareness: two devices measure the true distance between them | Core Specification 6.0 acknowledgments, 2026-10-13 |
| Enhancements for ISOAL | Pacing of Isochronous Adaptation Layer traffic | Core Specification 6.0 acknowledgments, 2026-10-13 |
| LL Extended Feature Set | Formalized link-layer feature negotiation | Core Specification 6.0 acknowledgments, 2026-10-13 |
| Monitoring Advertisers | How often a device needs to wake to track a peer | Core Specification 6.0 acknowledgments, 2026-10-13 |
| Frame Space Update | A negotiable timing parameter between frames | Core Specification 6.0 acknowledgments, 2026-10-13 |
Each one refines how Bluetooth devices discover, measure and pace their low-energy communication. Channel Sounding gets the headlines because it adds a capability rather than a tuning: two devices measure round-trip time between them to know the true distance, which find-my tags, digital keys and proximity unlocks have wanted for years.
None of the six feature areas touches the audio codec paths, which is the fact most audio buyers need. A "Bluetooth 6" line in a spec sheet is a radio and feature statement, not a sound-quality statement, and the codec row on the same spec sheet remains the place to read what audio the device supports.
What it means for audio
Nothing changes for sound. The audio negotiation on a Bluetooth 6.0 phone or headphone works exactly as on a 5.x radio: Classic A2DP codecs such as SBC, AAC, aptX and LDAC where the vendor enables them, and LE Audio where the product line carries it. That is the same discipline our iPhone LDAC profile and Xiaomi codec page apply to individual devices, and the 5.4 version page carries the equivalent record for the end of the 5.x line. Where two devices hold connections at once, the mechanics live on our Bluetooth multipoint page, and the profile layer underneath both paths is documented in our audio profiles reference.
FAQ
No codec changed. The 6.0 feature set is about distance awareness and link-layer efficiency, Channel Sounding, decision-based advertising filtering, monitoring advertisers, ISOAL enhancements, the LL extended feature set and the frame space update, none of which changes the Classic or LE audio codecs. Headphone audio on a 6.0 device negotiates codecs exactly as before.
A distance-awareness feature introduced in Core 6.0: two Bluetooth devices measure the true distance between them using round-trip timing and phase-based ranging rather than signal strength estimates. It targets find-my devices, digital keys and geofenced access, not audio, and it requires both devices to support it.
Yes, among current flagships: the Xiaomi 15 lists Bluetooth 6.0, the Pixel 10 lists Bluetooth v6 and the iPhone 17 lists Bluetooth 6 on its spec sheet. Support beyond flagships is still rolling through the market, and a 6.0 radio does not change which audio codecs a phone supports.
The 6.x line continued: Core 6.1 was adopted in April 2025 and Core 6.2 in November 2025, both listed as Adopted on the Bluetooth SIG specification pages. Version pages on this site carry the 5.x line for comparison.
