Connections & battery

6 items
Wired / wireless connections
Bluetooth 5.4 (A2DP, AVRCP, HFP); the case charges with a charging cable; no wireless charging

Samsung: 'charge the case using a charging cable'; 'Wireless charging is not supported'; no USB Type-C cable is included, and the case's wired charging port is not named on this page. Galaxy devices on One UI 8.0 or later use the phone's settings; earlier One UI uses the Galaxy Wearable app, which needs Android 11.0 or above with at least 1.5 GB of memory. Samsung Account login is required to set up the earbuds. Samsung's pairing statements conflict (see device_compatibility).

Source
Device compatibility
Samsung footnote: connecting as Bluetooth Audio is available regardless of the OS; Samsung FAQ: a Samsung Galaxy smartphone running Android 11.0 or later is required to pair

Both statements are on the same Samsung UK product page and are inconsistent: the feature footnote says 'Connecting Samsung Galaxy Buds as Bluetooth Audio is available regardless of the OS', while the FAQ says 'A Samsung Galaxy smartphone running on Android 11.0 or later is required to pair with Galaxy Buds3 FE.' Neither is chosen; local review should resolve which applies.

Source
Battery life
Music playback: earbuds up to 6 hours with ANC on (up to 8.5 hours with ANC off); with the charging case up to 24 hours with ANC on (up to 30 hours with ANC off). Talk time: up to 4 hours per charge and 18 hours with the case, with ANC on or off.

Samsung's rated figures from the UK specification table. Earbud battery 53 mAh, case 515 mAh (typical). No test conditions for these figures were found on the page.
