Overview

• The new build is 8A5343a, replacing the earlier 8A5324b release.
• Support is limited to AirPods Pro 2 and AirPods 4 in both USB‑C and Lightning versions, with no AirPods Max compatibility.
• A host iPhone, iPad, or Mac must run iOS 26, iPadOS 26, or macOS Tahoe, with Developer Mode enabled and the pre‑release AirPods firmware toggle selected in Settings.
• Features under test include camera remote controls, studio‑quality audio recording, clearer calls using Voice Isolation and beamforming mics, automatic pausing on sleep detection, and smoother CarPlay handoff.
• Apple notes the beta cannot be removed until a non‑beta update arrives, and publishers advise against installing on mission‑critical hardware.
