OnePlus Nord Buds 4 Pro Review: Strong ANC on a Budget

The OnePlus Nord Buds 4 Pro is for students, commuters and first jobbers who want proper noise cancelling and long battery life without paying mid-range prices. The trade-off is that much of the case rests on OnePlus’s own claims and one detailed hands-on review; we found no lab measurement of its ANC.

How good is the noise cancelling?

OnePlus claims up to 55 dB, with light, moderate, maximum and adaptive modes. Treat the dB figure as marketing; brands measure it differently. Smartprix’s reviewer, who rated ANC 9 out of 10, found it handled traffic, fan and outdoor noise well, with the maximum mode most effective. The transparency mode works but is described as nothing special.

How long does the battery last?

OnePlus rates each bud at 13 hours with ANC off and about 7 hours with it on, and up to 54 hours with the case. Smartprix saw about 8 hours of mixed use per charge, and under 5 hours on continuous calls. That is a full college day or a week of commuting before the case needs a top-up.

How does it sound?

The default tuning leans on bass, which Smartprix found too heavy. Its Serenade preset cleans up vocals, and the 10-band EQ fixes most of it. Mids can still sound recessed on some songs. LHDC 5.0 is supported on compatible Android phones; others fall back to AAC or SBC.

Are calls clear on a busy road?

Each bud has three microphones with AI noise reduction. Smartprix rated calls 8 out of 10, with wind handled well up to about 25 km/h. Very noisy places still let some background sound through, so expect it to cope with a moving scooter better than with a crowded railway platform.

Does it fit well for workouts?

Yes, according to Smartprix: secure, comfortable for long sessions and fine for workouts, at about 4.4 g per bud. The buds are IP55 rated, but the case is not rated, so keep it out of rain.

Is the app and Hindi support useful?

OnePlus’s HeyMelody app has gesture controls, find-my-earbuds and a real-time translation feature that OnePlus says supports Hindi and English. Smartprix noted no ads and no forced sign-in, which is rare in this price band.

What we could not verify

The warranty period, OnePlus’s service reach outside cities with its own service centres, and the exact fast-charge figure, which differs between OnePlus’s launch reports. It has been on sale only since March 2026, so there is little long-term evidence on durability or battery ageing.

Should you buy it?

For most buyers who want ANC on a budget, yes. It undercuts many mid-range earbuds on features, and its weak spots, default tuning and touch sensitivity, are fixable in the app.
