According to the SDPPI database listings, all three Samsung devices received certification on October 26, 2026. The Samsung Galaxy Fit 4 is listed under the model number SM-R391, while the other two products appear as SM-R545 and SM-U700. The latest listings suggest that Samsung is preparing these devices for the Indonesian market.
The SM-R545 is described as a TWS Bluetooth headset, whereas the SM-U700 is listed as a Bluetooth headset. The certification entries do not reveal any additional specifications or confirm the retail names of these two audio products.
Samsung Galaxy T1 Earbuds (SM-R545): Expected Features
The Samsung SM-R545 has previously been identified in Samsung app code under the internal codename ‘T1’. However, earlier reports referred to the same device as the Galaxy Buds Canal 5 so its final retail name remains uncertain.
Leaked illustrations have suggested that the upcoming earbuds could feature an ear-hook design. Previous software findings reveal expected features such as Earbud Fit Test, customisable touch-and-hold controls, noise-control switching, call rejection and quick access to Google Gemini or Samsung Bixby.
Each earbud could pack a 63mAh battery as was discovered in the software code, while the charging case may feature a 595mAh battery.
Samsung Galaxy Studio Headphones (SM-U700): Expected Features
The Samsung SM-U700 has been internally identified by the codename ‘H1’. Earlier app illustrations showed an over-ear headphone design with reports speculating that the device could launch as the Galaxy Studio headphones.
Previous software findings suggest that the headphones could offer noise controls, Ambient Sound, Conversation mode, head tracking and automatic power-off functionality.
The leaked illustrations indicate that a physical button on the left earcup could control noise-related features, while the right earcup may support touch gestures for media playback. It could automatically activate Ambient Sound when the wearer starts speaking to hear their surroundings without removing the headphones.
Meanwhile, an earlier TÜV Rheinland certification reportedly revealed a 5V/1A power input equivalent to 5W.
