ADVANCED 2-WAY SPEAKER
Hi-Fi sound. Hear the full range
Meet the true Hi-Fi Galaxy Buds. The advanced 2-way Speaker paired with dedicated Dual Amp is meticulously tuned to achieve high-fidelity sound across the full spectrum. Bring the studio-scale listening system to your ears, wherever you are.

2-way Speaker
Two separate drivers — the newly designed wider woofer with an expanded diaphragm area, and a precision tweeter — are expertly aligned to reproduce sound that remains faithful to the original recording. The advanced 2-way Speaker delivers a full-range performance, from deep, textured sub-bass to airy, extended highs, while preserving natural bass resonance with faster transient response, a rich midrange body and sharp detail.

Dual Amplifier
Each amplifier on Galaxy Buds4 Pro is dedicated to its own driver, expanding sound coverage while reducing distortion and interference through meticulous tuning. The result is a high-fidelity soundscape that immerses you in the full spectrum of sound.

ADVANCED WIRELESS AUDIO
Hear every layer come alive
Hear every layer come alive with extended bit depth and high sampling rates. Samsung Seamless Codec (SSC) supports 24-bit / 96 kHz audio to preserve the original sound with vast amount of information, while optimised data transmission control enables a stable listening experience with reduced audible artefacts or dropouts. Turn on the Ultra High Quality Audio (UHQ) option on your Galaxy smartphone and rediscover your favourite songs in full detail.

ADAPTIVE EQUALISER
Tailor Hi-Fi sound your way
Take a step closer to the ultimate in audio. Customise bass, treble and tone with the 9-Band Equaliser to match your preference, creating a sound signature tailored just for you. Galaxy Buds4 Pro also optimises sound adaptively to your ear shape and wearing style, ensuring a consistent listening experience as your ears perceive it — even when you adjust the volume.

SUPER CLEAR CALL
Super Clear Call, even in noise
Even your calls are clear like Hi-Fi audio. Your voice is clearly captured by 6 microphones positioned around your head, intelligently isolating it from the background sound with advanced Deep Neural Network (DNN). The exceptionally clean voice signal is transmitted with pure effortlessness through Super Wideband (SWB) up to 16 kHz between your Galaxy Buds4 Pro and Galaxy smartphone. Hear and be heard, loud and clear — even in noisy moments.

360 AUDIO

ENHANCED ANC
