Which is better for running and the gym?

The Galaxy Buds 3 Pro. Its IP57 rating is dust-tight and survives submersion, while the Technics is only IPX4 splash resistant. The Samsung is also lighter and sits more securely.

Which has better noise cancelling?

Both are strong. Reviewers rate the Samsung's ANC highly, and the Technics adapts automatically to your surroundings with eight microphones. The Technics edges ahead on call clarity.

Which lasts longer on a charge?

The Technics. It runs up to 10 hours with ANC on, against 6 hours for the Samsung, and its case adds 28 more hours.

Is the Technics worth stepping up to?

Yes for sound and battery. You get LDAC, Dolby Atmos with head tracking, three-device multipoint and longer playback. Skip it if you need a waterproof earbud for sport.

Do the Samsung Buds work with non-Samsung phones?

Yes, over Bluetooth with Android. Some features, like auto switch and full codec support, work best on Samsung devices.

Which is more comfortable?

Both get praise for fit. The Samsung is lighter, and the Technics is 10% smaller and 16% lighter than its predecessor with soft nozzles and several tip sizes.

Samsung Galaxy Buds 3 Pro vs Technics EAH-AZ100

The Technics EAH-AZ100 is the better pick for most people. It has stronger battery life, a three-device multipoint connection, LDAC and Dolby Atmos with head tracking, and owners rate it higher. The Galaxy Buds 3 Pro are lighter, fit more securely for sport, and carry a tougher IP57 rating, but their battery is short with ANC on and their reception is mixed. Choose the Technics for sound quality and all-day use; choose the Samsung for workouts and tight integration with a Galaxy phone.

Choose the Galaxy Buds 3 Pro if you want a light, secure in-ear for workouts and you own a Samsung phone or tablet.
Choose the Technics EAH-AZ100 if sound quality, long battery life and switching between several devices matter most.
