Samsung Galaxy Buds4 R540 - White
The Samsung Galaxy Buds4 (model SM-R540) are high-quality, open-style wireless earbuds released in 2026. They are designed for users who prefer a lightweight, non-sealing fit—similar to standard AirPods—while still wanting to benefit from deep integration within the Samsung Galaxy ecosystem.
Key hardware specifications: Audio driver: Single 11mm full-range driver; Connectivity: Advanced Bluetooth 6.1 with Auracast broadcast support; Durability: IP54 rating for dust and splash resistance (resistant to sweat and rain; not suitable for submersion); Battery life: Approximately 5 hours per charge for the earbuds; up to 24 hours of total playback time including the charging case; Case features: Compact cube design with a distinctive transparent/tinted lid; supports both USB-C and wireless charging. Design and fit: The Galaxy Buds4 depart radically from the older, bean-shaped Buds, opting instead for a design featuring a metal 'blade' stem. They are 'open-air' (non-sealing) earbuds, meaning they lack silicone tips. While this makes them very comfortable and airy for all-day use, YouTube reviewers note that the fit depends heavily on ear shape; for larger ears, they may easily fall out during intense workouts. Smart features and Galaxy AI: Pairing them with a Samsung device grants access to a comprehensive suite of exclusive features: High-Res Audio: Utilizes the Samsung Seamless Codec for 24-bit/96kHz audio. Spatial Audio: Supports 360 Audio with dynamic head tracking. Galaxy AI integration: Built-in support for real-time translation (Interpreter), Perplexity AI, and Google Gemini. Advanced controls: Stem-based gestures (pinch and swipe) for volume control, call management, and hands-free operation via head movements. Performance and considerations: Due to the open design, the effectiveness of the adaptive active noise cancellation (ANC) is limited. It reduces background noise by approximately 35% but cannot fully block out loud environments, as ambient sound naturally enters through the non-sealing fit. Call quality is exceptionally clear thanks to a 6-microphone system and noise cancellation powered by a Deep Neural Network (DNN).
