I made a fair few calls with the buds with no real complaints on either end. They tend to get testy with wind, but I found them up to the task for most scenarios.
The biggest get, the Air4 Pro’s noise canceling, is limited yet effective. It does a solid job rolling off low-frequency sounds like airplane drones, traffic, and other ambient noises, especially with some music playing. It’s not as successful as class-leading options like the Liberty 4 NC, but you’re also unlikely to pay as much for the privilege.
As expected, the Air4 Pro’s ANC struggles at subduing high-frequency sounds, from children yelling to keystrokes. The Liberty 4 NC and Space A40 both outdo them there, but you’ll have to step up to premium noise cancelers like the AirPods Pro (9/10, WIRED Recommends) or, above those, Sony’s WF-1000XM5 (7/10 WIRED Recommends) and Bose’s latest QuietComfort buds to successfully fend off those annoyances.
If you’re prone to using noise canceling without audio or with podcasts, you’ll likely hear some nominal buzzing and white noise with cancellation on. You’ll hear even more riffraff with the transparency mode engaged, which is far from the most natural-sounding version I’ve tested. But considering the price point, and the fact that plenty of comparable buds offer one or neither of these ambient sound modes, it’s difficult to raise much fuss.
Smooth Sound
As the most sophisticated and feature-packed Soundpeats buds I’ve auditioned, the Air4 Pro’s overall execution has been impressive. As usual, though, the sound quality is what first piqued my interest, and that remains the cornerstone of the experience.
The buds lead off with warm, full, and robust performance in the bass and lower midrange that confidently sets the stage for the other elements. Far from the muddy, bass-bombing buds that once ruled the budget set, the Air4 Pro’s bass is focused and chocolatey smooth. It hits heavily where it’s supposed to, but rarely overwhelms or masks other instruments. I turned it down a few notches after a few particularly thumpy tunes, and that’s where the EQ stayed.
From there, the midrange takes up the charge, reproducing instruments like vocals, guitar, and low strings with both body and clarity. Instrumental separation is refreshingly nimble, leaving room for details and instrumental textures to shine. The high frequencies take the biggest budget cut. Rarely did I notice any audible distortion or sharpness, but instruments like hot snares or cymbals are sometimes reproduced with a crisper, shoutier touch than my favorite options.
Apart from those occasional moments where things feel stretched too thinly, the Air4 Pro’s sound signature mostly hits the sweet spot for an inviting and engaging experience. I especially enjoyed listening to warmer, acoustic-forward productions, where woody guitars and smooth vocals are given their due.
When combined with the the Air4 Pro’s many features, a light and remarkably comfy fit, and their often shockingly low sale price, you’ve got a winning combination. You can outdo these buds by throwing down $100 or so, let alone stretching to $300 flagships, but if you find them for around $50 to $60 (where they’re priced as I write this review), grab them and run.
