OnePlus Nord Buds 4 Review India — Real ANC, 6-Mic Calls, and 54 Hours of Battery

OnePlus has quietly been building one of the best budget earbuds lineups in India. The Nord Buds 4 is their latest shot — and on paper, it reads like a spec sheet that belongs a tier above its price.

The OnePlus Nord Buds 4 launches on June 29 at 12 PM on Amazon India at a launch price of ₹3,099 (MRP ₹3,299). It packs real-time ANC, a 6-mic call system, 54 hours of total battery, 12mm drivers with Spatial Audio, and AI Translate — all in a 4.3-gram earbud with IP55 dust and water resistance. That's a feature list that directly challenges earbuds at twice the price.

We dug into the specs, the design choices, and how this compares to its Pro sibling to help you decide whether the Nord Buds 4 earns a spot in your daily carry.

OnePlus Nord Buds 4 TWS Earbuds: Full Review

The first thing that stands out is the real-time Active Noise Cancellation. OnePlus claims up to 52dB of noise reduction across a wide frequency range (1000Hz and 3000Hz), which covers the droning hum of buses, AC units, and office chatter — the sounds most Indian commuters actually need blocked. ANC at this price point was rare even a year ago; the Nord Buds 4 makes it a baseline expectation.

The 6-microphone setup (3 per earbud) handles the calling side. OnePlus uses AI-powered noise reduction to isolate your voice from background sound — useful for calls taken on busy streets, auto rides, or open-plan offices. The difference between 4-mic and 6-mic systems shows up most clearly in windy outdoor conditions, where cheaper earbuds tend to pick up wind noise alongside your voice.

Sound Quality — 12mm Drivers, Spatial Audio, and Custom EQ

The Nord Buds 4 runs 12mm dynamic drivers tuned for what OnePlus calls "extra punchy bass for more crunchy beats" — their way of saying the low end is boosted out of the box. For listeners who prefer a more neutral profile, the Sound Master EQ and Custom Equaliser in the HeyMelody app let you reshape the sound to your preference.

Immersive Spatial Audio adds a three-dimensional soundstage with multiple modes — Gaming, Immersion, and Mixed — so you can tailor the effect depending on whether you're watching a film, gaming, or just listening to music. At this price, having selectable spatial modes rather than a single toggle is a nice touch.

Battery — 54 Hours Total, 11 Hours Per Earbud

Battery life is a genuine strong suit here. The Nord Buds 4 delivers up to 13 hours per earbud (ANC off, 6.5 hours with ANC on) on a single charge, with the case extending that to 54 hours total. That's comfortably over two weeks of daily commute use without touching a charger.

Fast charging is equally impressive: 10 minutes of charge gives 11 hours of playback. That's not a typo — a quick top-up before you leave the house covers an entire day and then some. The case has passed 1,000+ bending cycle tests for hinge durability, so the lid should hold up to daily pocket abuse.

Build and Comfort — 4.3g, IP55, Built to Endure

At 4.3 grams per earbud, the Nord Buds 4 is among the lightest ANC earbuds available in India. The in-ear design uses smooth, rounded edges that OnePlus says are optimised for all-day extreme comfort — a claim that matters most during long calls or full-day wear at a desk.

IP55 dust and water resistance goes a step beyond the IPX4 found on most budget earbuds. IP55 covers not just sweat and splashes but also dust ingress — relevant for anyone commuting on Indian roads, running outdoors, or working in dusty environments. The buds are also rated for 1,000+ bending cycles on the case hinge, which speaks to long-term build confidence.

Connectivity — Bluetooth 6.1, Multipoint, and AI Translate

The Nord Buds 4 runs Bluetooth 6.1 — the latest standard — with dual-device multipoint connectivity for seamless switching between phone and laptop. The standard Bluetooth effective distance is 10 metres, with Google Fast Pair and Microsoft Swift Pair for instant setup on Android and Windows devices.

Pairing is fast via Google Fast Pair and Microsoft Swift Pair, and OnePlus adds their OneShake gesture feature for customisable controls.

The standout connectivity feature is AI Translate — real-time translation during conversations, turning the earbuds into an on-the-go interpreter. It's a niche feature but genuinely useful for travellers or anyone navigating multilingual interactions in India's diverse linguistic landscape.

Nord Buds 4 vs Nord Buds 4 Pro — Which One Should You Pick?

OnePlus sells both side by side, so the comparison is inevitable. Here's where they differ:

The Nord Buds 4 wins on battery life (54 vs 44 hours) and weight (4.3g vs 4.6g). The Nord Buds 4 Pro wins on ANC depth (49dB vs 52dB), audio fidelity (dual driver + LDAC codec for Hi-Res audio), and overall sound range. If you mostly listen to Spotify/YouTube and want maximum battery, the standard Buds 4 is the better pick. If you're an audiophile who cares about codec quality and needs stronger noise cancellation, the Pro justifies the premium.

ANC at This Price — What to Realistically Expect

ANC on budget earbuds has improved dramatically, but it's worth setting expectations. At the Nord Buds 4's price, 52dB of noise cancellation handles consistent low-frequency sounds well — AC hum, bus engine drone, fan noise, and the general murmur of a coffee shop. It won't silence a loud metro announcement or the person talking next to you on a crowded train — that level of isolation requires the deeper ANC found on earbuds like the Samsung Galaxy Buds Core or the Nord Buds 4 Pro. For daily commuting and office use in India, 52dB is genuinely useful — just don't expect library-level silence.

Battery Life — How 54 Hours Translates to Real Use

Quoted battery numbers always assume moderate volume (50-60%) and ANC off. With ANC on and volume at 70-80% — a realistic scenario for noisy Indian commutes — expect roughly 6-7 hours per earbud and 25-30 hours total from the case. That's still comfortably over a week of daily use. The 10-minute quick charge covering 11 hours means even worst-case, you're never stuck without audio for long. For how this stacks up against the competition, our wireless earbuds roundup compares battery life across the top picks in every price bracket.

Frequently Asked Questions

Does the OnePlus Nord Buds 4 have real ANC or just passive noise isolation?

Real Active Noise Cancellation — not just passive isolation from the ear tip seal. The Nord Buds 4 uses microphones to detect and counteract ambient noise in real time, reducing it by up to 52dB. This is a meaningful step up from earbuds that rely solely on the physical seal of the ear tip to block sound. You'll notice the difference most clearly in environments with constant background noise — offices, buses, flights — where ANC actively cancels the low-frequency drone that passive isolation alone can't fully block.

How does AI Translate work on the Nord Buds 4?

AI Translate provides real-time translation during conversations. The feature uses your phone's processing to translate spoken language and deliver it through the earbuds, effectively turning them into a live interpreter. It supports multiple languages and works through the HeyMelody or OnePlus companion app. It's particularly useful in India's multilingual context — navigating conversations across language barriers in different states, dealing with customer service in an unfamiliar language, or travelling where English isn't widely spoken.

Is IP55 better than IPX4 for sweat and gym use?

Yes — IP55 is a step above IPX4. The "5" in IP55 means the earbuds are protected against dust ingress (not just water), and the second "5" means protection against low-pressure water jets from any direction, not just splashes. For gym use, both ratings handle sweat fine. The practical difference shows up in dusty outdoor environments — running on unpaved roads, commuting on dusty Indian highways, or using earbuds at construction sites — where IPX4 earbuds have no dust protection rating at all. IP55 covers both scenarios.

Can I use the Nord Buds 4 with an iPhone or non-OnePlus Android phone?

Yes — the Nord Buds 4 works with any Bluetooth device. Google Fast Pair enables instant pairing on Android phones, and standard Bluetooth pairing works on iPhones. You'll get the full audio experience, ANC, and basic controls on any phone. Some features like AI Translate and advanced EQ customisation require the HeyMelody app (available on both iOS and Android), while OnePlus-specific features like OneShake may be limited to OnePlus devices.

Should I buy the Nord Buds 4 or wait for a sale?

OnePlus typically offers launch discounts and bank card offers during the first few weeks of availability, plus deeper drops during Amazon Prime Day (July 4-6 this year) and the Great Indian Festival (September-October). If you need earbuds now, the launch pricing is usually competitive. If you can wait a few weeks, Prime Day could bring the price down further — it's one of the best windows for earbuds deals in India. Either way, the feature set at this price point is strong enough that you're unlikely to feel shortchanged at the launch price.

Final Thoughts

The OnePlus Nord Buds 4 packs a feature set that punches well above its weight — real ANC, 6-mic calling, 54-hour battery, IP55, Bluetooth 6.1, and AI Translate in a 4.3g package. It's not trying to be an audiophile's dream (the Pro exists for that), but as a daily-use earbud for Indian commuters, students, and remote workers, the balance of comfort, battery, and noise cancellation is hard to fault at this price.
