Galaxy Buds 4 and Buds 4 Pro support a much newer version of Bluetooth

With each new generation of Galaxy Buds, Samsung improves both audio quality and usability. The company also regularly adopts newer wireless codecs and connectivity standards to enhance overall performance.

The Galaxy Buds 4 and Galaxy Buds 4 Pro continue that trend by featuring a newer version of Bluetooth.

Samsung has confirmed that the Galaxy Buds 4 and Galaxy Buds 4 Pro support Bluetooth 6.1. This is a significant upgrade over Bluetooth 5.4, which is used in the Galaxy Buds 3 series.

Unfortunately, the South Korean firm doesn't seem to have introduced any newer audio codec, as both its new earbuds still top out at SSC UHQ that offers 24-bit/96kHz audio.

Bluetooth 6.0 was introduced in August 2024, followed by Bluetooth 6.1 in May 2025. Together, these versions focus on improving power efficiency, reducing latency, enhancing device tracking accuracy, and strengthening privacy.

Bluetooth 6.0 delivers lower latency, better power efficiency, and more precise distance measurement between connected devices. It uses advanced channel sounding technology to calculate how far apart devices are, enabling highly accurate distance estimation under ideal conditions.

Bluetooth 6.1 builds on that foundation with stronger privacy protections and additional power optimizations, particularly in crowded wireless environments.

In real-world use, these improvements could result in a more stable connection in busy places such as airports, offices, and shopping malls.

You may experience fewer lip-sync issues while watching videos and lower latency when playing games. Improved power efficiency could also translate into longer battery life, especially in areas where many nearby devices, such as smartphones, smartwatches, and wireless earbuds, are competing for wireless bandwidth.
