Overview
- Leaked One UI 8.5 animations depict a more compact, curvier Buds 4 Pro with flatter stems and the removal of the Buds 3 series light strip.
- The charging case shifts to a horizontal layout with a button beside USB‑C to ring the paired phone, and visuals hint at a case speaker for audible locating.
- A new Head Gestures feature in the code enables nods and head shakes to answer or reject calls, manage notifications, dismiss alarms or timers, and reply yes or no to an AI assistant.
- The assets also reference 360 Audio/recording, Adaptive Noise Control, Quick Pairing, Phone Locator, and retained pinch or swipe stem controls.
- Firmware traces cite codenames “Handel” (Buds 4) and “Bach” (Buds 4 Pro), with reports of a small case battery bump as a rumor and an expected launch alongside Galaxy S26 that has not been confirmed.
