There’s a very specific kind of product I’ve come to appreciate over time. The ones that don’t try too hard. They don’t scream for attention or rely on hype. They just work, quietly and consistently.
That’s exactly how the OnePlus Nord Buds 3 Pro felt to me.
No drama, no hype. Just a pair of earbuds that delivered where it mattered. Sound, ANC, battery, price. Everything clicked in a way that made them easy to recommend, especially at ₹2,999.
And then the Nord Buds 4 Pro showed up at ₹3,999.
Now this isn’t just about a good pair of earbuds anymore. It’s about whether OnePlus has actually refined something that was already working, and more importantly, whether that refinement is worth ₹1,000 extra. Because that’s the real question here. Not “are these better?” but “are they better enough?”
Design: Familiar, But More Refined
Put both of these side by side, and the first thing you notice is how familiar they look. OnePlus hasn’t gone for a dramatic redesign, and honestly, that works in its favour. The Nord Buds 3 Pro already had a practical design. That oval-shaped case was compact, pocket-friendly, and easy to carry around.
The 4 Pro keeps that idea but trims it down slightly. The case is now a bit smaller, lighter, and feels more refined in hand. It’s not a huge difference on paper, but it does add up in daily use.
The earbuds themselves follow the same approach. Still the same stem-style design, but now slightly longer and slimmer. It’s a small tweak, but it actually improves grip and comfort.
With the 3 Pro, I occasionally had to adjust the fit during longer sessions. The 4 Pro feels more stable and sits better in the ear. Comfort is largely similar otherwise, since both weigh around 4.4 grams per earbud.
Both models also come with an IP55 rating, so sweat, dust, and light splashes aren’t a concern. That said, I do wish OnePlus pushed for a higher rating on the newer model. It feels like a safe upgrade they could have made, especially at the higher price.
In terms of colours, the 3 Pro sticks to Soft Jade and Starry Black, while the 4 Pro shifts to Radiant Gray and Raven Black. The colour options this time feel more muted but also more premium. I’ve been using the black variant, and it looks clean and understated while still feeling premium.
Features: Small Upgrades, Big Difference
Moving to features, the Nord Buds 3 Pro already had a solid base. The HeyMelody app gave you EQ controls, dual device connectivity worked well, and there were even small extras like using the earbuds as a camera shutter.
All of that carries over, but the 4 Pro adds refinements that you notice quickly. The biggest one is volume control directly on the earbuds. Swipe gestures make a real difference in day-to-day use. Once you get used to it, going back feels inconvenient.
There’s also onboard AI this time. It sounds like a headline feature, but it’s actually quite practical. You can trigger your phone’s assistant, use AI translation, or quickly access features without picking up your phone.
Touch controls are also more consistent. The 3 Pro had moments where gestures wouldn’t register properly. The 4 Pro feels more reliable, and the slightly larger touch area helps with that.
Connectivity: Quietly Getting Better
Connectivity is another clear upgrade. The 3 Pro runs on Bluetooth 5.4, while the 4 Pro moves to Bluetooth 6.0. It might not sound dramatic, but in real-world use, connections feel more stable, switching between devices is smoother, and overall responsiveness is better.
You also get better codec support this time. The 3 Pro is limited to AAC and SBC, while the 4 Pro adds LHDC 5.0. That’s a meaningful upgrade if you’re using a compatible device, as it allows for higher bitrate audio and better detail.
Sound Quality: Less About Size, More About Tuning
Now, sound quality.
The Nord Buds 3 Pro already impressed me. It uses a larger 12.4mm dynamic driver, and that results in a warm, balanced sound signature. Tracks like “Paint The Town Red” by Doja Cat or “Houdini” by Dua Lipa sound clean and enjoyable. The bass has enough punch, vocals are clear, and nothing feels overly aggressive.
The 4 Pro goes slightly smaller with a 12mm driver, but the tuning is noticeably better. Listening to tracks like “Espresso” by Sabrina Carpenter or “FE!N” by Travis Scott, the difference becomes clear. Bass feels deeper but tighter, vocals are more forward, and there’s better separation between instruments.
It’s not just louder or bassier, it’s cleaner and more controlled. And with LHDC 5.0 and spatial audio support, the experience opens up further. You get more detail and a wider soundstage, especially when watching content.
Also worth mentioning, both earbuds work seamlessly with Android and iOS, so you’re not tied to any specific ecosystem.
ANC: From Good to Properly Effective
ANC is another area where the 4 Pro improves things. The 3 Pro already offered up to 49dB noise cancellation and handled everyday environments well. Offices, traffic, and general background noise were manageable.
The 4 Pro pushes this to 55dB and improves overall effectiveness. It’s not just about the number. In real-world scenarios, especially in busier environments like cafés or during commutes, the difference is noticeable. You hear less of the outside world without needing to increase volume.
Calls: Finally Cleaner Outdoors
Call quality also gets better. The 4 Pro uses a 6-microphone setup, compared to a simpler setup on the 3 Pro. Combined with AI noise reduction, voices come through clearer, especially outdoors where wind and background noise can be an issue.
Battery Life: Lab Numbers vs Real Life
Battery life is where things start to separate more clearly. The Nord Buds 3 Pro packs a 58mAh battery per earbud and a 440mAh case. On paper, that gives you up to 5.5 hours with ANC and 12 hours without. Even now, I’m still getting around 4 to 4.5 hours with ANC on, which is respectable after extended use.
The 4 Pro increases this with a 62mAh battery in each earbud and a 530mAh case. On paper, that translates to up to 13 hours on the buds and 54 hours with the case. But those are lab-tested numbers under ideal conditions.
In real-world usage, with ANC on and volume around 60 to 70 percent, I was getting closer to 6 to 6.5 hours. That’s a noticeable improvement and enough to get through a full day without worrying about charging.
Charging speeds remain similar, around an hour for the earbuds and roughly 90 minutes for the full setup, using a Type-C port.
Verdict: Is It Worth ₹1,000 More?
The Nord Buds 3 Pro is still a very good pair of earbuds. At ₹2,999, it remains one of the easiest recommendations if you’re looking for solid sound and features without spending too much.
But the Nord Buds 4 Pro at ₹3,999 feels like a more refined product. It improves on multiple small areas that collectively make a difference. Better tuning, stronger ANC, more reliable controls, LHDC 5.0 support, newer Bluetooth, improved battery life, and a slightly more polished design.
At a ₹1,000 higher price, the upgrade isn’t dramatic, but it is meaningful.
If your priority is saving money, the 3 Pro still makes perfect sense. But if you’re willing to spend a bit more for a more complete and future-ready experience, the 4 Pro is the better pick.
It doesn’t reinvent anything. It just gets more things right.
