Samsung Galaxy Buds4 Inalámbricos Bluetooth ANC 30 h Negro

Samsung Galaxy Buds4 SM-R540 Black

The Samsung Galaxy Buds4 SM-R540 are True Wireless Stereo earbuds with active noise cancellation (ANC) and high-fidelity audio capabilities designed for everyday use. They feature an 11mm dynamic driver that delivers a balanced frequency response and support 24-bit/96kHz playback via the exclusive SSC-UHQ codec, setting them apart from most TWS earbuds in their class. With up to 30 hours of total battery life when combining the earbuds and charging case, they’re perfect for both long days and travel. They’re compatible with Android and iOS and fully integrate with the Samsung Galaxy ecosystem via the Galaxy Wearable app.

ANC and Listening Modes

The Galaxy Buds4 R540’s active noise cancellation (ANC) continuously analyzes ambient noise and neutralizes it before it reaches your ears, making it particularly effective on public transportation, in open-plan offices, or on busy streets. Additionally, Ambient Sound mode lets you hear your surroundings without removing the earbuds, which is useful when you need to stay alert to announcements or conversations. Using ANC has a direct impact on battery life: the earbuds last 5 hours with ANC on versus 6 hours with ANC off, so switching between modes depending on the situation can extend your listening time.

Hi-Fi audio architecture with SSC-UHQ and 9 bands

The Samsung Seamless Codec (SSC-UHQ) transmits audio at 24-bit/96 kHz, a resolution that far exceeds the 16-bit/44.1 kHz of a CD and is not available in standard codecs like SBC or AAC. This translates to greater detail in transients, a wider soundstage, and fewer compression artifacts. The 11mm dynamic driver handles both deep bass and crisp highs with ease. Added to this is a 9-band equalizer accessible via the Galaxy Wearable app, which lets you adjust the sound signature to your personal taste or the music genre, from pop to jazz to movie audio.

6 microphones and Galaxy AI for perfect calls

The Galaxy Buds4 R540 feature 6 microphones strategically placed to capture the voice from different angles and cancel background noise using a DNN neural network. The VPU (Voice Pickup Unit) detects jaw vibrations to isolate the speaker’s voice even in windy conditions or with intense background noise—a feature that sets them apart from comparable earbuds that rely solely on ambient microphones. Additionally, the Galaxy AI Interpreter feature offers real-time simultaneous translation, a practical tool for both meetings with speakers of other languages and for travelers who need to communicate abroad without losing conversational fluency.

Battery Life and Charging: Up to 30 Hours of Uninterrupted Use

The charging case features a 515 mAh battery that extends total battery life to up to 30 hours with ANC off or 24 hours with ANC on—enough for several days of moderate use or a full long-haul flight. Charging is done via USB-C, and the case also supports wireless charging, allowing you to recharge on any Qi-compatible pad without the need for cables. This dual charging method provides flexibility both at home and on the go.

Lightweight in-ear design and IP54 rating

Weighing just 4.6 g per earbud, the Galaxy Buds4 R540 are barely noticeable during extended use, thanks to their ergonomic in-ear design that seals the ear canal without causing excessive pressure. The IP54 rating ensures protection against water splashes from all directions and dust ingress, making them suitable for workouts involving sweat, light rain, or dusty environments. The case weighs 45.1 g, and its compact dimensions allow it to fit in any pocket, making it easy to carry around daily in Black.

Bluetooth 6.1, Auracast, and universal compatibility

Bluetooth 6.1 improves connection stability in environments with high wireless signal density, such as airports or shared workspaces, reducing interruptions and latency. Supported profiles include A2DP, AVRCP, HFP, PBP, and TMAP, covering everything from high-quality stereo playback to voice calls and audio use cases for multiple simultaneous listeners. Auracast technology, based on the PBP profile, allows users to receive public audio broadcasts in spaces such as waiting rooms, museums, or events. Accelerometer and gyroscope sensors enable touch controls and headset position detection. Full compatibility is available with Android and iOS, with enhanced integration on Samsung Galaxy devices.
