Galaxy Buds4 Series Elevates Call Clarity with HD Voice

At the recent Galaxy Unpacked event, Samsung Electronics introduced the most advanced Galaxy Buds to date. Galaxy Buds4 Series sound as good as they feel, with hi-res audio¹ and design innovations that maximize everyday wearability. The Galaxy Buds4 series redefines the experience of using premium earbuds - prioritizing quality and comfort.

Galaxy users can instantly connect Buds4 Pro or Buds4 to the ecosystem of devices they already enjoy by simply opening the Buds cradle.² When paired with the Galaxy S26 series, together they deliver crisp and clear conversations.

From juggling work calls to catching up with loved ones, you'll hear the difference loud and clear with HD voice.³

How does HD voice work?

The clarity begins with advanced AI-powered noise reduction. The Galaxy Buds4 series uses multiple microphones that collect sounds from different directions, along with a Voice Pick Up Unit (VPU) which helps detect and prioritize users' voices. Advanced networks then analyze the sound in real time to separate speech from background noise such as traffic, wind, or other nearby conversations.

Traditional Bluetooth calls capture voice frequencies with a limited bandwidth, causing speech to sound compressed and less natural. HD voice preserves more natural detail during communications by doubling the Bluetooth bandwidth to 16kHz, called super wide band. HD voice also uses machine learning models trained for noise reduction and voice enhancement to enable a wider range of the human voice to be transmitted.
