Samsung recently introduced the new Galaxy Buds 4 Series at its Galaxy Unpacked event. These wireless earbuds are made to give users better sound, a comfortable design, and clearer phone calls in daily life.

HD Voice is one of the latest and most important features of the Galaxy Buds 4 series. This feature helps make phone calls sound clearer and more natural. Whether you are talking to coworkers, friends, or family, HD Voice helps you hear every word more clearly.

The earbuds use smart AI technology to reduce background noise. The Galaxy Buds 4 have several microphones that collect sound from different directions. They also include a special part called a Voice Pick Up Unit (VPU). This helps the earbuds recognize the user’s voice and focus on it during a call.’

Meanwhile, the system reduces other sounds around you, such as traffic noise, wind, or people talking nearby. This helps the person on the other side hear your voice better.

HD Voice also works by increasing the Bluetooth sound range. Normal Bluetooth calls use a limited range, which can make voices sound less clear. The Galaxy Buds 4 increases the range to 16kHz, which is super wideband. This allows more voice details to be sent during a call. Due to this, small sounds like “s,” “z,” “th,” and “f” are easier to hear. These sounds are important because they help people understand words correctly.

The Galaxy Buds 4 Series also connects easily with Samsung Galaxy devices. Users can simply open the earbuds case near their Galaxy phone to connect quickly. When paired with the Galaxy S26 series, the earbuds provide even better call quality.

Users can turn on HD Voice by going to Settings >> Galaxy Buds >> Sound Quality and Effects >> Advanced Quality Options >> Super Wide Band Speech.
