- Which has better noise cancelling?
- Both are strong. The Buds 4 Pro adapts ANC to your surroundings and adds Voice Detect. The EAH-AZ100 uses adaptive noise cancelling that adjusts in real time. Reviews call both excellent; the Technics edges ahead on pure isolation for most listeners.
- Which lasts longer on a charge?
- The Technics. It runs 8 hours per charge and 29 hours with the case with ANC off. The Buds 4 Pro runs 6 hours with ANC on and 26 hours with the case.
- Is the Technics worth the extra $58?
- Yes if you want LDAC sound, longer battery and three-device multipoint. No if you own a Galaxy phone and value 360 Audio, translation and the IP57 rating more.
- Can I wear either in the rain?
- The Buds 4 Pro has IP57, so it handles rain and brief immersion. The EAH-AZ100 is IPX4, which covers sweat and light splashes only.
- Which is better for calls?
- The Technics has eight microphones plus Voice Focus AI and JustMyVoice. The Buds 4 Pro has six microphones with Samsung voice processing. Both are clear; the Technics has the hardware edge.
- Which fits better for small ears?
- The EAH-AZ100 ships with multiple ear tip sizes and soft nozzles, and reviewers call it comfortable. The Buds 4 Pro has a secure in-ear fit, but its shape suits some ears less well.
