Google's Opus HD Joins Hi-Res AUDIO WIRELESS
On 15 July 2026 the Japan Audio Society (JAS) added Google's Opus HD to its Hi-Res AUDIO WIRELESS codec list — the seventh codec certified since the logo launched in 2018, and the first built on an open internet standard rather than a single company's own technology. The same release quietly revised headphone certification itself, adding a low-frequency verification that every certified product must now pass. One change is loud; the other reaches further.
By the Numbers what the release actually says
- 7certified Hi-Res AUDIO WIRELESS codecs — Opus HD is the newest
- 48 kHzOpus's own ceiling — the codec behind WebRTC and YouTube
- 96 kHzOpus HD's ceiling, per its still-unfinished IETF draft
- 1 yeartransition period for the new low-frequency rule
- 2018the year the Hi-Res AUDIO WIRELESS logo — and its codec list — began
The Two Stories one loud, one quiet
The loud one
A codec joins the club
- Opus HD (Google LLC) becomes the seventh codec certified for Hi-Res AUDIO WIRELESS since the logo launched in 2018.
- The first codec built on an open internet standard (IETF's Opus, RFC 6716) in a club otherwise built from six competing, company-owned codecs.
- No product carrying it has been reported. A month earlier, Google's own Pixel line gained hi-res Bluetooth audio through a rival's codec, LHDC, not Opus.
The quiet one
A new bar for all
- Headphone and earphone certification gains a low-frequency verification, under IEC 60268-7.
- Effective immediately, with a one-year transition period to comply.
- Applies to every certified headphone or earphone, whether or not it ever uses Opus HD.
| Standing | What | Where it comes from |
|---|---|---|
| Confirmed | Opus HD (Google LLC) is certified as Hi-Res AUDIO WIRELESS's seventh codec, and the same release also revises headphone certification to add a low-frequency verification, effective immediately with a one-year transition. | JAS's own release, 15 Jul 2026 |
| Confirmed | A certified codec alone does not earn the logo: a Hi-Res AUDIO WIRELESS product must also meet the wired Hi-Res AUDIO logo's own spec for everything other than the wireless link. | JAS's own release, 15 Jul 2026 |
| Confirmed | No product built on Opus HD has been reported. A month before the certification, Android 17's first stable build had already added hi-res Bluetooth audio to Pixel phones — through LHDC, a rival's codec. | SoundGuys and Android Authority, both Jun 2026 |
Bottom line
Google's Opus HD — an extension of the open, royalty-free internet codec behind WebRTC and YouTube — becomes the seventh codec certified for Japan's Hi-Res AUDIO WIRELESS logo, while the same release quietly raises what every certified headphone has to measure up to.
What the certification does not show
A codec being certified says nothing about products: nothing built on Opus HD has shipped, and Google's own most recent Bluetooth hi-res move — on Pixel, weeks earlier — went to a different codec entirely.
Timeline
Eight Years, Seven Codecs every addition to the list, dated at JAS's own site
- 28 Nov 2018The Hi-Res AUDIO WIRELESS logo launches. LDAC (Sony) is the founding certified codec.
- 12 Sep 2019LHDC (Savitech) is certified.
- 9 Nov 2022SCL6 (MQA Ltd.) and LC3plus (Fraunhofer IIS) are certified together.
- 2 Jun 2023SHDC (SYNCOMM Technology Corp., Taiwan) is certified.
- 26 Oct 2023aptX Adaptive (Qualcomm Technologies International) is certified.
- 12 Jun 2026The IETF publishes the “Opus HD” scalable-extension draft, authored by a Google engineer — not yet a finished standard.
- 16 Jun 2026Android 17’s stable build begins rolling out to Pixel 6 and later. Six days on, readers notice it has brought LHDC to Pixel phones — Google’s own Bluetooth hi-res move, and not Opus.
- 15 Jul 2026JAS certifies Opus HD (Google LLC) as the seventh codec, and revises headphone certification to add the low-frequency verification.
Nothing in the record dates a moment when Opus HD reaches a real product. The certification is the newest, and last, entry on this timeline.

The Argument
What “Opus HD” Actually Is a draft extension, not a JAS figure
Opus, the codec Google's extension builds on, is already the audio behind WebRTC and YouTube: an open, royalty-free standard set by the Internet Engineering Task Force (RFC 6716), built to handle sampling rates up to 48 kHz and an audio bandwidth up to 20 kHz. JAS's own certification release names no sampling figure for Opus HD at all — it describes the codec only as an extension with Google's engineers involved, compatible with Bluetooth Low Energy. The number usually quoted for it, 96 kHz, comes from a separate document: an IETF draft, authored by a Google engineer, still working through the standards process rather than a finished RFC. That draft describes a scalable extension layer — one that can carry audio above 20 kHz up to 96 kHz and refine detail below it, while staying fully compatible with an ordinary 48 kHz Opus stream in either direction. It sets no single fixed bit depth or bitrate; the extra bits are allocated per frequency band and scale with what is available.

Why an Internet Codec, in This Club what it is entering, and what it matches
Every codec already on the Hi-Res AUDIO WIRELESS list is licensed by a single company: LDAC by Sony, LHDC by Savitech, SCL6 by MQA, LC3plus by Fraunhofer IIS, SHDC by SYNCOMM, aptX Adaptive by Qualcomm. Opus HD is the first built on a codec whose base specification is set by an internet standards body rather than owned by one licensor. It also targets Bluetooth's newer Low Energy Audio profile, whose own baseline codec — LC3, specified by the Bluetooth SIG — tops out at 48 kHz, the same ceiling ordinary Opus already reaches without any extension. And a 96 kHz ceiling is not new to this list on its own terms either: Sony's own description of LDAC states that it transmits Hi-Res Audio content “without down-converting” from 96 kHz/24-bit. What Opus HD changes is not the number a device can already reach on this list — it is who sets the format that gets it there.
What Others Add
What the Wired Spec Already Required and what the 2025 IEC edition adds to it
Hi-Res AUDIO (wired)
The baseline every WIRELESS product still has to clear
- Analogue: 40 kHz or higher high-frequency performance.
- Digital: formats and interfaces at 96 kHz/24-bit or higher.
- A WIRELESS product must clear this baseline for everything except the wireless link itself — the codec list only ever covered that one part.
IEC 60268-7 (2025 edition)
What the revision now points to
- The international standard for headphone/earphone measurement, 4th edition, published 2025.
- Its headline technical change: an added “effective frequency range” measurement.
- JAS's revision cites this exact edition for the new lower-limiting-frequency requirement.
The Pixel Story That Actually Happened a month before the certification
For years Google's Pixel phones lagged behind other Android handsets on Bluetooth codecs, limited to AAC or LDAC while phones from Huawei, Xiaomi and OnePlus supported LHDC — a codec that has shipped in the Android Open-Source Project since Android 10. That changed with Android 17's stable build, which began rolling out on 16 June 2026; the LHDC support it carried was noticed and reported six days later. Pixel phones gained it with a 96 kHz ceiling on Pixel devices (LHDC's newest version supports up to 192 kHz on other hardware). Google Pixel Buds Pro 2 do not support it; the earbuds that do are chiefly non-Google models such as the Nothing Ear 2 and OnePlus Buds Pro 3. None of this involves Opus or Opus HD at all — it is Savitech's codec, already years old, finally reaching Google's own phones.
Conclusion
So What
The quiet change is the bigger one
A codec addition benefits whichever product adopts it, if any ever do. The low-frequency verification applies to every certified headphone and earphone immediately, with no adoption decision required from anyone. Measured by reach, the quiet half of this release outweighs the loud half.
What to watch
Whether Opus HD reaches a shipping product, on Pixel or elsewhere, given that Google's own most recent Bluetooth hi-res move went to LHDC instead. How manufacturers already carrying the Hi-Res AUDIO marks respond to the low-frequency rule inside its one-year transition. And whether the IETF draft the “96 kHz” figure comes from is finalised as an RFC, amended, or dropped.
- Products, not certifications. Watch for Opus HD in shipping firmware or silicon — certification is step one, and step two has not happened yet, on Pixel or anywhere else.
- The low-frequency rule's one-year clock. Whether it visibly reshapes headphone tuning before the transition ends.
- The IETF draft's fate. A work-in-progress extension can still change before it becomes a finished standard, if it ever does.
