WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Samsung Galaxy Buds3 Pro

What it brings

Replaceable S/M/L ear tips, ANC and ambient listening provide fit and noise-control options.
Manufacturer source
The charging case accepts USB-C or wireless charging; a USB cable is supplied.
Manufacturer source Manufacturer source
Pinch controls manage playback and calls, with swipe controls for volume.
Manufacturer source

What to check

24-bit/96 kHz UHQ audio, 360 Audio and Auto Switch have Samsung-device and software conditions; a Bluetooth connection alone does not establish those features.
Manufacturer source
The IP57 rating applies to the earbuds. The charging case is not water resistant, and wet earbuds must be dried before charging.
Manufacturer source
Samsung’s battery figures are conditional maxima, and ANC-on music ratings are lower than ANC-off ratings. A mains or wireless charger is sold separately.
Manufacturer source Manufacturer source

Samsung Galaxy Buds4 Pro

What it brings

Samsung lists a 2-way woofer-and-tweeter speaker with dual amplifiers plus Voice Detect and Siren Detect; the Galaxy Buds4 has a 1-way driver with a single amplifier and Samsung says those two detection features are Buds4 Pro features.
Manufacturer source Manufacturer source Manufacturer source
IP57 rating on the earbuds (Samsung says the Charging Case is not water resistant), three sizes of ear tips in the box and a wirelessly charged case.
Manufacturer source

What to check

The Galaxy Wearable app is not supported on iOS, so iPhone owners get Bluetooth audio without Samsung's controls; elsewhere the app needs Android 12.0 or later, while Galaxy devices on One UI 8.0 or later use the phone's own settings.
Manufacturer source
Neither a USB-C cable nor a wireless charger is included, and each earbud weighs 5.1 g, heavier than the 4.6 g Galaxy Buds4.
