Samsung Galaxy Buds4 R540 Black

Samsung Galaxy Buds4 (SM-R540)

With the Galaxy Buds4, Samsung refreshes its range of wireless earphones by adding Bluetooth 6.1 connectivity and a high-fidelity audio system supporting 24-bit / 96 kHz. In contrast to the Pro variant, this model omits silicone ear tips in order to favour ergonomics and a natural awareness of the surroundings.

These earphones likewise incorporate Galaxy AI functions, including simultaneous translation during conversations, along with compatibility with the Samsung Galaxy ecosystem so that all its advanced features can be used.

Hi-Fi audio architecture with SSC-UHQ

Every earpiece houses an 11mm dynamic driver built to provide a balanced frequency response and clear reproduction throughout the whole sound spectrum.

Digital audio processing relies on Samsung Seamless Codec Ultra High Quality (SSC-UHQ), which can transmit audio at 24-bit / 96 kHz. This streaming quality is offered when paired with Samsung Galaxy devices compatible with One UI 6.1.1 or later. With other devices, the connection uses the standard AAC or SBC codecs.

Bluetooth 6.1 and Auracast technology

Thanks to Bluetooth 6.1, connection stability is improved and latency is reduced in environments with heavy wireless signal saturation.

The Galaxy Buds4 are compatible with Auracast, a technology that makes it possible to receive public audio streams or share content with several compatible devices.

The Auto Switch function lets you move automatically between different Samsung devices linked to the same account, for instance smartphones, tablets or Galaxy Watches.

IP54 design and resistance

The design lowers in-ear pressure and lets you perceive your surroundings naturally, which improves comfort during long sessions.

The body uses the Blade Design, featuring a flat ear bud optimised for touch gestures.

The earphones carry IP54 certification, offering protection against dust and resistance to splashes of water or sweat.

Active Noise Cancellation (ANC)

In spite of their open architecture, they include Active Noise Cancellation (ANC) based on software algorithms. This system is designed to lessen constant low-frequency noise such as motors or ventilation systems.

ANC does not aim to isolate the user completely, but instead to keep a balance between noise reduction and awareness of the surroundings.

Voice pickup is handled by three microphones and a VPU (Voice Pickup Unit) that senses jaw vibrations to improve call clarity and filter out wind noise.

Galaxy AI and autonomy

Integration with Galaxy AI makes it possible to activate the Interpreter mode, which plays real-time translations straight into the earphones during conversations in different languages.

They provide up to 6 hours of continuous use with ANC off and up to 30 hours of total battery life using the additional charges in the case.

Power management is optimised by the new Bluetooth 6.1 compatible chip.
