The Samsung Galaxy Buds 4 mark a transition toward software-defined audio experiences, where AI plays a central role in sound processing and user interaction. Equipped with adaptive active noise cancellation and dynamic equalization, the earbuds continuously adjust audio output based on environmental conditions and user behavior. The integration of Bluetooth 6.1 enhances connectivity stability and reduces latency, particularly within the Galaxy ecosystem. AI-driven features such as real-time translation and context-aware sound adjustments highlight a shift beyond traditional audio playback into intelligent assistance. Rather than focusing solely on driver hardware, the Buds 4 leverage software algorithms
