Every AirPod runs Apple AAC over Bluetooth, and Apple states it plainly: "Bluetooth connections aren't lossless." The record here is model by model: the AirPods 5, Pro 3 and Max 2 spec pages list "Bluetooth 5.3 wireless technology" and no codec; older cohorts sit in Apple's AAC list; the newest models take the two lossless exits instead, wired or Vision Pro. Apple publishes no Bluetooth bitrate for any AirPod: the only AAC figure on the current spec pages is the battery test's playlist encoding, not a radio rate.
Figures on this page were checked October 2026. Every table row carries its source and access date.
Per-model codec record
Apple publishes its codec story on the lossless-audio support page, and not as a codec table: one sentence lists which headphones use the Apple AAC Bluetooth Codec, and the newest models are simply not in it. The matrix below combines that sentence with each model's own spec page, including the pages that no longer exist.
| Model | Specs page | Documented codec record | Source / as of |
|---|---|---|---|
| AirPods 5 | Live: "Bluetooth 5.3 wireless technology" | No codec enumeration on the page; not named in the AAC cohort sentence; on the Vision Pro lossless list ("AirPods 4 or later") | Apple specs + 118295, 2026-10-28 |
| AirPods 4 and AirPods 4 with Active Noise Cancellation | No live spec page (legacy URLs redirect or 404) | Not named in the AAC cohort sentence ("AirPods 3 or earlier" stops below); both variants on Apple's compare roster; on the Vision Pro lossless list | 118295 + compare page + URL checks, 2026-10-28 |
| AirPods Pro 3 | Live: "Bluetooth 5.3 wireless technology" | No codec enumeration on the page; not in the cohort sentence; named on the Vision Pro lossless list | Apple specs + 118295, 2026-10-28 |
| AirPods Pro 2 with Lightning Charging Case | No live spec page (legacy URLs 404) | Named in the AAC cohort sentence, verbatim | 118295, 2026-10-28 |
| AirPods Pro 2 with USB-C Charging Case | No live spec page | Outside the cohort sentence; on the Vision Pro lossless list ("Pro 2 with USB-C Charging Case") | 118295, 2026-10-28 |
| AirPods Max 1 (USB-C) | No live spec page (the airpods-max URL now serves Max 2) | In the cohort sentence as "AirPods Max"; the lossless sentence names this model "AirPods Max 1 (USB-C)" | 118295, 2026-10-28 |
| AirPods Max 2 | Live: "Bluetooth 5.3 wireless technology" | No codec enumeration on the page; wired lossless (same sentence); not on the Vision Pro list | Apple specs + 118295, 2026-10-28 |
| AirPods (3rd generation) | No live spec page (URL redirects to the AirPods 5 page); on the compare roster in two case variants | In the AAC cohort sentence ("AirPods 3 or earlier") | 118295 + compare page + URL checks, 2026-10-28 |
| AirPods (2nd generation) | No live spec page (URL redirects); on the compare roster | In the AAC cohort sentence | 118295 + compare page + URL checks, 2026-10-28 |
| AirPods Pro (1st generation) | No live Apple page (not on the compare roster; legacy spec URLs 404) | Named in the AAC cohort sentence ("AirPods Pro 1") | 118295 + URL checks, 2026-10-28 |
Spec-page statuses checked by URL on October 28, 2026: legacy addresses either redirect (301) to the AirPods 5 page or return 404; the per-URL list sits in the sources.
Two more cohorts live outside the matrix. Beats: the cohort sentence covers "most Beats wireless headphones", and Powerbeats Pro 2 is the one Beats model on the Vision Pro lossless list. And from an iPhone, every AirPod plays AAC, because iPhones negotiate AAC and SBC only, which our iPhone record keeps as the source-side story.
The retirement pattern matches the iPhone: when a generation leaves the lineup, its spec page goes with it, redirecting to the current page or returning 404. Apple's compare tool is where the older models still have official company: eleven variants in the roster, from the AirPods 5 to two third-generation listings, with the first-generation Pro absent. The AAC cohort sentence remains the one place Apple speaks for all of them at once.
SBC, AAC and the missing numbers
A2DP, the stereo Bluetooth profile every AirPod speaks, has one mandatory codec and a rule for the rest. The mandatory one is SBC: the specification requires an encoder in every source and a decoder in every sink. The rule is that an optional codec runs only when both ends support it. The negotiation therefore depends on both sides of the link, and each side has its own record here.
The source side is the settled half: iPhones negotiate AAC and SBC only. The sink side is the cohort sentence: Apple AAC, per Apple. What no Apple page this profile cites does is enumerate SBC, and that absence is checkable across all three current spec pages. The specification fills the gap: the SBC decoder is mandatory in every A2DP sink, which is why an AirPod pairs with anything, and SBC is what runs when a source has no AAC to offer.
Then the numbers. Apple publishes no Bluetooth bitrate for AirPods: the lossless-audio page names the codec and stops, with no rate anywhere in its full text. The wider AAC landscape, a 264 kbps cited maximum and 320 kbps as Android's stack default, lives on our AAC profile; SBC's official ladder runs 127 to 345 kb/s with the 328 kb/s joint-stereo example, on our SBC profile.
One trap is worth fencing off. The only AAC figure on the current AirPods spec pages sits in the battery footnote, where the test playlist consisted of "358 unique audio tracks purchased from the iTunes Store (256-Kbps AAC encoding)". That 256 describes the encoding of the test files, not the radio. Quoting it as an AirPods Bluetooth bitrate would be wrong twice over.
The lossless exits
Apple's sentence is the record: "Bluetooth connections aren't lossless." Two exits exist, and both leave standard Bluetooth behind.
The wired exit: "You can listen to lossless audio with AirPods Max 1 (USB-C) and AirPods Max 2": with the included USB-C cable, current firmware on the headphones, and current software on the iPhone, iPad or Mac. A cable, in other words, doing what the radio won't.
The Vision Pro exit: Apple's page lists what can receive lossless on Vision Pro: its built-in speakers, AirPods 4 or later, AirPods Pro 3, AirPods Pro 2 with USB-C Charging Case, or Powerbeats Pro 2. Apple doesn't describe the radio technology behind that link on this page. Only the working combinations. What the list quietly shows is the boundary: lossless wireless reaches only the newest models, and only on one device.
The rest of the AirPods line stays where it has always been: AAC over Bluetooth, transparent for most listeners on most material, and lossy in the math.
What this means in practice
- Lossless subscriber with AirPods: the subscription's top tier needs the wired Max or the Vision Pro combination; over Bluetooth, every AirPod plays AAC.
- AirPods with non-Apple sources: AAC or SBC by negotiation: same ceiling as with an iPhone, no aptX or LDAC lane to unlock.
- Shared listening: Apple TV 4K sends to "up to two pairs of compatible AirPods or Beats headphones" per Apple's guide: an Apple-ecosystem sharing feature, not a Bluetooth codec change; our Apple TV profile covers it.
- Auracast venues: AirPods cannot join Auracast broadcasts, per the record our AirPods Auracast profile keeps; Auracast and LE Audio appear nowhere on the three current spec pages either, re-checked October 2026.
Every brand page in this section ends the same way, because the physics does: the source and the sink must agree, and Apple's side of the agreement is AAC. Where Sony, Sennheiser and Bose sell hi-res ladders, Apple sells one well-tuned codec and two carefully fenced exits from it. The fences are documented. That's what this page keeps.
FAQ
Apple AAC over Bluetooth, per Apple's own support page, which lists the AAC cohort model by model. SBC sits underneath as the universal A2DP fallback; AAC is the lane Apple optimizes.
No. Apple's documented codec lane is AAC, and iPhones themselves negotiate AAC and SBC only. The same ceiling cuts both ways: aptX- or LDAC-rated headphones drop to AAC with an Apple source, and AirPods have no aptX or LDAC lane to offer anyone.
Not over Bluetooth. Apple states "Bluetooth connections aren't lossless." The wired exit is USB-C to AirPods Max 1 (USB-C) or AirPods Max 2; the wireless exit is Vision Pro with AirPods 4 or later, AirPods Pro 3, Pro 2 with USB-C case, or Powerbeats Pro 2.
No. Apple's support page names the codec and stops there. No bitrate figure appears anywhere on the lossless-audio page this profile cites.
No Apple page this profile cites enumerates SBC for AirPods. The A2DP specification fills the gap: SBC is the mandatory codec of the profile, a decoder in every sink, so an AirPod accepts it from any source that has no AAC to offer. With Apple sources the link runs AAC.
