Overview
- Reports based on the leaked assets show a more compact, curvier look that drops the Buds 3 series’ Blade Light while keeping pinch and squeeze stem controls.
- The charging case appears to shift to a horizontal lay‑flat design with USB‑C and a button that can ring the paired phone, and visuals hint at a possible case speaker for locating the case itself.
- Animations describe new Head Gestures that detect nods and shakes to answer or reject calls, hear or stop notification readouts, dismiss alarms and timers, and respond to yes/no prompts for an AI assistant.
- Carried‑over capabilities listed in the code include Adaptive Noise Control (ANC), 360° audio recording, a Find Your Phone function, and seamless pairing or multipoint with phones and tablets.
- Firmware references cite internal codenames “Handel” (Buds 4) and “Bach” (Buds 4 Pro), with some reports noting a small case battery bump, and all details remain unconfirmed by Samsung.
