ASamsung Galaxy Buds+

Feature	Needs
Original companion apps	Original mobile requirement is Android 5.0 or later with at least 1.5 GB RAM, or iPhone 7 or later with iOS 10 or later. Galaxy Buds Manager firmware updates support Windows 7, 8, 8.1 or 10, or macOS 10.8 or later. Current mobile app requirements can differ.
Bixby touch activation	Compatible Bixby phone and voice-command hold assignment. Assigning volume to hold uses both sides and prevents Bixby hold activation.
Ambient sound	Adjust in Galaxy Wearable. Extra-high amplification is enabled in Labs. It can cause feedback with poor fitting ear tips.
Hear own voice during calls	Enable Use Ambient sound during calls in Galaxy Wearable Advanced settings.
Gaming mode	Compatible Samsung Android phone with Galaxy Wearable Labs. Not an iOS feature.
Auto Switch	Later earbud firmware and compatible Galaxy devices with One UI 3.1 or later, signed into the same Samsung Account. The original 2020 account pairing feature alone was not automatic audio routing.
Buds Together and Music Share	Compatible Galaxy host and software. Current maker host eligibility explicitly includes Buds+. Sharing one stream with another earbud pair is separate from concurrent connections to multiple audio sources.
Microsoft Swift Pair	Windows 10 version 1803 or later and compatible earbud software. Samsung Easy Pair on phones is a separate pairing route.
SmartThings Find	Registered Samsung account and compatible updated Galaxy apps on Android 8 or later. Buds+ must be charged and out of the case to emit the BLE finding signal. Saved last location can remain available when disconnected. The case is not asserted to broadcast.
Wind noise reduction	Firmware processing described in R175XXU0ATD3 and R175XXU0ATE3 updates. Applies to calls or Ambient Sound operation, not adaptive ANC or a selectable wind mode.
