What to Expect from the Galaxy Buds 4 Pro’s 2026 Launch

Samsung is actively developing its next-generation wireless earbuds. New evidence confirms work is underway on the Galaxy Buds 4 and a premium Galaxy Buds 4 Pro model. The earbuds are expected to launch early next year. They will likely debut alongside the Galaxy S26 smartphone series.

Firmware for the new audio devices has appeared on Samsung’s servers. This is a clear sign that the development process is moving forward. According to Reuters, such internal milestones typically precede a product launch by several months.

One UI 8.5 Leak Reveals Key Model Details

A recent leak of the upcoming One UI 8.5 software provided the first solid clues. Code within the firmware explicitly names the unreleased earbuds. The data identifies the model SM-R640 as the “Galaxy Buds 4 Pro.”

A second model, SM-R540, is labeled as the standard “Galaxy Buds 4.” This information was extracted from text strings deep within the software build. It offers the most reliable confirmation of the product names to date.

Server Listings Signal Advanced Testing Stage

Further evidence has emerged from Samsung’s own servers. A firmware version for the Galaxy Buds 4 Pro, labeled R640XXU0AYI1, was recently logged. This indicates the company has begun internal testing of the device’s software.

Such testing is a critical step before mass production can begin. It allows engineers to refine performance and ensure stability. This progression suggests a launch timeline in the first quarter of 2025 is highly probable.

Rumors Point to Significant Feature Upgrade

Industry analysts anticipate major upgrades for the Galaxy Buds 4 Pro. Samsung may integrate Ultra-Wideband (UWB) technology into the new model. This would enable more precise device tracking and new seamless connectivity features.

The design is also expected to see revisions. The goal will be to improve comfort and sound quality. These enhancements would help Samsung compete more aggressively with other premium earbuds on the market.

The emergence of firmware for the Galaxy Buds 4 Pro solidifies its place in Samsung’s 2025 roadmap. Consumers can expect a significant audio upgrade when these earbuds launch with the next Galaxy S series.
