360 Audio and head tracking	Compatible Galaxy Android One UI 3.1+ phone/tablet or listed Samsung TV. Direct multi-channel requires One UI 4.1.1+. App/content support varies.
Auto Switch	Supported Galaxy devices signed into same Samsung Account. Galaxy Book One UI 6.0+, phones/tablets One UI 4.1.1+, Watch 4 or later. Samsung TV 2022 or later after required firmware. This is device switching.
Live translation and Interpreter	Compatible Galaxy AI phone and latest required software. Samsung Account and supported language package can be required. Translation is performed on phone.
Gaming Mode	Samsung Android mobile device only.
Voice commands and Bixby	Bixby-compatible phone for assistant. Fixed voice commands are limited to supported languages and installed matching language package.
Windows audio	Use compatible Windows Bluetooth adapter. Exact Buds3 Pro maker pairing guide uses case-bottom connect button held for 3 seconds, then Windows Bluetooth device pairing. Microphone operation is not inferred from the music-pairing guide.
Windows firmware updates	Samsung Galaxy Buds PC app from Microsoft Store explicitly supports Buds3 Pro. Fully charge buds, put them in case and open lid for connection, then Earbuds software update. This is distinct from legacy Galaxy Buds Manager for older models, so no Mac app support is inferred.
