Thankfully, noise cancellation is a different story on the Galaxy Buds 4 Pro. It’s still not going to silence the world like the second-gen Bose QuietComfort Ultra Earbuds can, but Samsung’s tech does just enough to make it useful in most circumstances. I found it particularly adept at blocking moderate levels of constant noise, like a clothes dryer, fan or white noise machine. It’s the sudden jolts of racket where the Pro struggles. The Buds 4 Pro also does a decent job at muffling human voices, which caused my family much frustration.
