WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Google Pixel Buds Pro 2

What it brings

The case supports both USB-C and Qi-certified wireless charging and has a ringtone speaker for Find Hub, so a misplaced case can be located.
Manufacturer source
Each earbud carries three microphones, a voice accelerometer and wind-blocking mesh, alongside ANC with Silent Seal 2.0, Transparency mode and Conversation Detection.
Manufacturer source

What to check

Full feature access requires a Google Account and an Android 6.0 or newer phone; iPhones can pair over Bluetooth, but Google ties the complete feature set to Android.
Manufacturer source
Google's specification pages do not list supported audio codecs or multipoint connection, and the earbuds are rated IP54 while the case is only IPX4.
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.
