Upcoming Launch Timeline and Model Numbers
Samsung is actively developing the Galaxy Buds 4 and Buds 4 Pro, with a potential launch expected in early 2026, likely coinciding with the Galaxy S26 series release. Recent leaks from a One UI 8.5 build have revealed the model numbers for these upcoming earbuds: the Galaxy Buds 4 will be designated as SM-R540, while the Buds 4 Pro will carry the model number SM-R640. This follows Samsung's established naming convention, as the previous generation, the Galaxy Buds 3 and Buds 3 Pro, were labeled SM-R530 and SM-R630, respectively.
Firmware Testing and Features
Samsung has commenced firmware testing for the Galaxy Buds 4 Pro, with the build version identified as R640XXU0AYI1. This testing phase is a standard procedure prior to product launches, indicating that the company is making significant progress in development. While specific features remain largely undisclosed, expectations include enhancements in noise cancellation, audio quality, and possibly AI-driven functionalities. There is speculation that Samsung may introduce a heart rate sensor in the Buds 4 Pro, similar to features anticipated in Apple's AirPods Pro 3, although this remains uncertain.
Context of One UI 8.5
The One UI 8.5 build not only provides insights into the new earbuds but also hints at broader software updates for Samsung devices. The upcoming One UI 8.5 is expected to debut alongside the Galaxy S26 series, showcasing design changes aimed at improving user experience. These changes include a cleaner interface for the Settings app and other core applications, reflecting Samsung's commitment to modernizing its software ecosystem.
Criticism & Opposition
While the anticipation for the Galaxy Buds 4 and Buds 4 Pro is palpable, some industry observers have expressed skepticism regarding Samsung's ability to compete with Apple’s offerings, particularly concerning advanced features like health monitoring. Critics argue that without significant innovation, Samsung may struggle to differentiate its products in a saturated market.
Official Statements & Responses
Samsung has not issued official statements regarding the specific features or launch dates for the Galaxy Buds 4 and Buds 4 Pro. However, the company’s ongoing firmware testing and the recent leaks suggest a focused effort on delivering a competitive product in early 2026.
