OnePlus Nord Buds 4 Review: Warm Sound, 52dB ANC, and a Better Fit Than the Specs Suggest

Introduction

The OnePlus Nord Buds 4 review starts with the kind of promise that gets attention fast: 52dB ANC, 54-hour battery life, AI Clear Call, and a Rs 3,299 price tag. The real test is whether those numbers still matter once you use them for work, music, videos, and calls. And honestly, that’s where things get interesting.

On paper, the Nord Buds 4 are trying to do a lot. But after a week of real use, they come across less like a flashy spec exercise and more like a pair of earbuds that are simply easy to live with. That distinction matters more than people sometimes admit. Specs can pull you in, sure. Daily comfort is what keeps you there.

Why the Nord Buds 4 feel more convincing in daily use than on paper

The first thing that stands out is not a single headline feature, but the overall balance. The Nord Buds 4 land as a polished pair of TWS earbuds under Rs 4,000 rather than a spec-chasing outlier. That may sound like faint praise at first, but it really isn’t. In this segment, balance is a kind of superpower.

At Rs 3,299, they are framed against a crowded field where nearly every pair claims ANC, bigger drivers, long battery life, and AI features. So the real question is not whether the Nord Buds 4 have enough features. It’s whether those features fit together well enough that you stop thinking about them. And in day-to-day use, they mostly do.

That’s why this review keeps circling back to the same idea: the numbers are good, but the experience is better than the numbers suggest. You might notice that with some products, the spec sheet is the main event. Here, the spec sheet is just the entrance.

Design, fit, and the kind of comfort that makes a pair easy to keep on

The case is compact and chic, with a hinge that snaps shut firmly and a teal finish that looks clean, even if it may wear over time. The earbuds use a tried-and-true stem design, and the fit is described as superb. That matters more than people think. A lot of earbuds sound fine until you wear them for two hours, and then they start reminding you they exist. These don’t do that nearly as much.

The Nord Buds 4 sit securely without feeling forced, which is a nice middle ground. They’re the sort of earbuds you can pop in and forget about during a commute, a work session, or a short walk outside. That comfort also helps the sound make more sense, because a stable fit improves the seal and keeps bass from feeling thin or inconsistent.

They also carry an IP55 rating, which means they should handle sweat during workouts and light rain. The default ear tip works well, but the extra pairs in the box are there if you need a better seal. That’s not exciting, maybe, but it’s the kind of practical detail that quietly improves the whole experience.

How the Nord Buds 4 sound compared with the Realme Buds Air 8

The sound profile is warm, bass-forward, and easy to listen to for long stretches. That makes the Nord Buds 4 appealing to casual listeners, even though the Realme Buds Air 8 comes across as more detailed and cleaner in direct comparison. If you like a lively, forgiving sound that doesn’t lean too clinical, the OnePlus tuning will probably feel friendlier right away.

It’s not trying to impress you with razor-edged separation or ultra-bright detail retrieval. Instead, it takes the softer, more relaxed route. For a lot of people, that’s the better everyday choice. Music feels less demanding. Podcasts sound natural. Videos are easy to keep on in the background. There’s a kind of comfort in that, even if audiophiles may raise an eyebrow.

Bass and vocals lean smoother on the OnePlus pair

In Childish Gambino’s “Retro,” the sub-bass is more noticeable on the Nord Buds 4, while the Realme pair keeps it tighter. In “Feel Good Inc” by Gorillaz, the Realme Buds Air 8 gives the guitar bassline more depth, clearer vocals, and more open laughter effects. That comparison says a lot. The Nord Buds 4 don’t chase maximum precision, but they do give bass a fuller, smoother shape that can feel more enjoyable with pop, hip-hop, and general streaming.

Vocals sit in a comfortable place too. They’re not especially forward, but they’re not buried either. So if you’re the kind of listener who wants a warm cushion around the music instead of a spotlight on every tiny detail, these land well.

Higher frequencies are a little less clean than on the Realme Buds Air 8

On “Dawn of the Iconoclast” by Dead Can Dance, the Nord Buds 4 sound a bit shrill in the higher ranges, and the opening percussion feels weaker than on the Realme pair. Still, the differences are small enough that the OnePlus sound remains enjoyable rather than distracting. That’s the key thing here. The Nord Buds 4 don’t sound sterile or badly tuned. They just aren’t as crisp at the top end as the best in class.

For many listeners, that trade-off is perfectly fine. Slightly softer highs can even make long listening easier. The sound may not wow you in a quick demo, but it settles in nicely over time.

The default tuning can be adjusted if you want more control

The tests were done on the Balanced EQ preset with BassWave turned off. BassWave can dynamically boost bass, and the HeyMelody app also includes Gaming mode for low-latency play. That means you’re not locked into the out-of-box sound if you want to tweak things later. The default tuning is already friendly, but the app gives you a little room to shape it more to your taste.

• Balanced EQ preset: used for the listening tests
• BassWave: disabled during testing, but available for extra bass
• Gaming mode: available inside the HeyMelody app for faster-paced titles

That flexibility is useful because not everyone wants the same sound all day. Some people want stronger bass for workouts. Others want a flatter response for vocals or movies. Having those options tucked away in the app makes the Nord Buds 4 feel more complete without making the experience complicated.

52dB ANC, transparency mode, and the AI Clear Call system

The Nord Buds 4 handle office chatter, keyboard clacks, traffic, AC noise, fans, and vacuum cleaners well enough for everyday use. The 52dB ANC ceiling is strong, even if the Realme Buds Air 8 pushes a little further with 55dB. In real life, though, the difference is smaller than the numbers suggest. Both are good enough to take the edge off busy environments, which is what most people actually need.

High mode is the more aggressive option, while Moderate mode is slightly less forceful but still effective. Transparency mode is usable for brief conversations and announcements, though voices still sound as if there is a thin layer between you and the room. That’s pretty normal at this price, and it’s still handy when you need to hear what’s going on without removing the earbuds.

If you’re commuting, working in a shared office, or trying to focus at home, the ANC is one of the best practical parts of the package. It doesn’t make the world disappear completely. It just lowers the volume of life enough that your music or calls can breathe.

Calls are helped by the six-microphone AI Clear Call system

The earbuds also do a solid job on calls, with OnePlus leaning on AI to improve clarity. That makes the six-microphone AI Clear Call system one of the more useful features here rather than just a spec bullet. Voices come through with enough confidence that you don’t feel like you need to repeat yourself every other minute.

Now, let’s be realistic. This isn’t magic. A windy street or a noisy café can still leak into the conversation. But for normal indoor use, and even for decent outdoor conditions, the call quality is dependable. And that’s really what people want when a company talks up AI in earbuds: not a miracle, just something that works without drawing attention to itself.

Battery life, fast charging, and the practical stuff you notice after a week

Battery life is one of the Nord Buds 4’s strongest arguments. In testing, they lasted 11 hours and 12 minutes with ANC off, FLAC audio playing continuously, and volume at 80 percent. That’s a very respectable result, especially when you remember the price. A lot of cheaper earbuds talk big about endurance and then quietly fall short once you actually use them hard. These don’t really do that.

OnePlus claims up to 54 hours of total playback with ANC off, 6.5 hours on the earbuds with ANC on at 50 percent volume, and 27 hours including the case. After the drain test, a short charge brought the earbuds back to 90 percent, which makes the fast-charging support feel genuinely useful. This is the kind of battery story that matters in real life because it reduces anxiety. You’re not constantly checking the percentage.

And that’s the thing with good battery life: you stop noticing it, which is exactly the point. You charge less. You worry less. You just use the earbuds.

The table tells a simple story: the Nord Buds 4 are not just claiming endurance, they’re backing it up in a way that should feel reassuring for most buyers. Fast charging adds another layer of convenience, especially if you tend to forget charging until the last minute. We’ve all been there.

HeyMelody app controls, Fast Pair support, and the extra features worth noticing

Pairing is straightforward thanks to Google Fast Pair and Microsoft Swift Pair. After that, most of the useful control lives in the HeyMelody app, which keeps the interface simple and split across two screens. That simplicity is welcome. You don’t have to dig through a maze of menus just to change the basics.

The main screen shows battery life, noise control, dual connection, equaliser, and game mode. The second screen handles touch controls for both earbuds, and there is also Spotify Tap, AI assistant gestures, and an AI-powered translation feature. That’s a pretty healthy list for a budget-friendly pair, but the nice part is that it doesn’t feel crammed in for no reason.

Some earbuds give you plenty of features and make them annoying to use. The Nord Buds 4 do a better job of making them feel accessible. That’s an underrated kind of polish.

• Google Fast Pair
• Microsoft Swift Pair
• Dual connection
• Equaliser
• Game mode
• Touch control customization for left and right earbuds
• Spotify Tap
• AI assistant trigger gestures
• AI-powered translation

Dual connection, in particular, is one of those features you don’t think about until you’ve used it. Then it’s hard to go back. If you bounce between a phone and a laptop often, it makes the whole setup feel a lot more practical.

FAQ

These are the smaller doubts that come after the main comparison: whether the Nord Buds 4 are really better than the competition in the ways that matter, and which buyer type will actually enjoy them.

Q: Are the OnePlus Nord Buds 4 better than the Realme Buds Air 8?

Not across the board. The Realme pair is ahead in sound detail, transparency mode, and ANC, especially if you care about those differences closely. But that doesn’t automatically make the Nord Buds 4 the worse buy. They still have a smoother, warmer presentation that some people will prefer day to day.

Q: Do the Nord Buds 4 have good battery life?

Yes. The review found 11 hours and 12 minutes in testing with ANC off, and OnePlus claims up to 54 hours total playback. That combination makes them feel genuinely dependable rather than merely adequate.

Q: Is the AI Clear Call system actually useful?

It seems to be. Calls are described as dependable, and the six-microphone setup does enough to justify the feature instead of leaving it as marketing noise. In practice, that means you can take calls without feeling like the earbuds are fighting against you.

Q: Who should buy these earbuds?

Listeners who prefer a warmer, more relaxed sound and want a comfortable, feature-rich pair at Rs 3,299 are the best match. If you care more about everyday comfort than chasing the most technical sound signature, these make a lot of sense.

Conclusion

The OnePlus Nord Buds 4 do not win every technical comparison, but they fit the intent behind the search: warm sound, reliable battery life, workable ANC, and a comfortable daily experience at Rs 3,299. That mix is more meaningful than it may sound at first. In a market full of earbuds trying to win your attention with bigger numbers, these win by being easy to keep using.

If you care more about how the earbuds feel across a whole day than about winning a spec battle, these are easy to consider. And that’s the final takeaway here: the Nord Buds 4 may not shout the loudest, but they make a pretty convincing case once you actually live with them.
