OnePlus Nord Buds 4 Review: 52dB ANC at Rs 3,299 With 54-Hour Battery

OnePlus launched the Nord Buds 4 in India on June 25, 2026, at Rs 3,299, with general sale opening on June 29. The numbers on the spec sheet read closer to a flagship pair of TWS earbuds: 52dB active noise cancellation, 12mm titanium-coated drivers, and 54 hours of battery life with the charging case. Each earbud weighs 4.3g, the pair carries an IP55 dust and water resistance rating, and they pair over Bluetooth 6.1 with dual-device support. None of those specs would look out of place on a pair of earbuds costing two or three times as much.

Hands-on with the Nord Buds 4 over several days, the experience largely matches the brochure, with the usual budget compromises concentrated in places most listeners won’t notice on day one. The default tuning stays balanced, with the bass present but tightly controlled, a noticeable departure from the bass-first mash that defines most sub-Rs 4,000 earbuds. The active noise cancellation delivers the kind of reduction that cheaper pairs only gesture at, and there are real tradeoffs too: treble harshness on certain tracks, and a scratch-prone case finish.

The Spec Sheet That Reads Above Its Weight

The headline numbers are the 52dB active noise cancellation depth, the 12mm titanium-coated drivers, and the 54-hour combined battery life with the case. OnePlus tested the noise cancellation across an ultra-wide 5,000Hz range, per the full Nord Buds 4 launch specifications. The 12mm driver is paired with what OnePlus calls 3D Spatial Audio, plus a Game Sound Spatial Audio mode that the company says is tuned for BGMI, FreeFire, and Call of Duty. None of those specs would look out of place on a pair of TWS earbuds costing significantly more.

Each earbud weighs 4.3g, a figure OnePlus flags in its launch copy as part of a ‘barely-there feel.’ Six microphones handle voice pickup and noise reduction during calls, with the company claiming voice clarity holds at wind speeds up to 25 km/h. The buds carry an IP55 dust and water resistance rating, the same level you’ll find on many fitness-first wireless earbuds.

On the connectivity side, the Nord Buds 4 support Bluetooth 6.1, Google Fast Pair, Microsoft Swift Pair, and Dual Device Connection. OnePlus lists the wireless range at up to 250 metres under ideal conditions, a number that matters more for marketing than for any practical use case. The earbuds also support AI Translate and AI Assistant integration on compatible phones, features that work through OxygenOS 12.0 and above on OnePlus handsets. Battery health is TÜV Rheinland certified, which is more relevant to long-term buyers than to anyone testing the earbuds over a few days.

• 52dB active noise cancellation across a 5,000Hz range
• 12mm titanium-coated dynamic drivers
• 54 hours total battery life with the charging case
• 4.3g per bud
• IP55 dust and water resistance
• Rs 3,299 standard price (Rs 3,099 introductory)

A Default Tuning That Skips the Bass-First Trap

Most affordable wireless earbuds tune their default sound signature to push bass hard, which tends to bury vocals and soften the rest of the mix. The Nord Buds 4 default to something closer to balanced, with the bass present but tightly controlled. Across a mixed playlist spanning Michael Jackson tracks and the Cocktail 2 soundtrack, the layering in vocals and the snap on percussion sat further forward than is typical for the price.

The treble tuning is where OnePlus clearly aimed: high hats and the upper register of vocals come through with a clarity that sub-Rs 4,000 earbuds rarely deliver. Bass heads who want the usual skull-rattling profile can switch to a dedicated Bass mode in the HeyMelody app, which delivers exactly the heavier thump the default tuning holds back. A flat-EQ option in the same app lets listeners dial the bass down further for spoken-word podcasts and acoustic tracks. The flexibility is one of the more interesting choices OnePlus made here, given how locked-down most budget TWS apps are.

The same crisp treble that makes percussion sparkle can turn harsh on tracks with already-aggressive high notes. At higher volumes on Kawa Kawa, the vocals and high-frequency strings sat at the edge of uncomfortable, a tradeoff to flag for anyone who listens to a lot of high-pitched vocal tracks. It is a minor quirk in an otherwise versatile tuning.

Game Sound Spatial Audio works through OnePlus’s Game Sound mode, which the company says is calibrated for BGMI, FreeFire, and Call of Duty. On OnePlus phones running OxygenOS 12.0 and above, the mode can be activated directly from the Bluetooth settings’ Earbuds Function. On iOS 13.2 and Android 8.0 and above devices, it requires the HeyMelody app. The mode works without affecting the rest of the audio profile, so it stays out of the way for music and calls.

How the Noise Cancellation Performs in Daily Use

Active noise cancellation on budget TWS earbuds has a track record of being a checkbox feature that barely changes the listening experience. The 52dB adaptive ANC on the Nord Buds 4 actually reduces ambient noise at this price point, where cheaper options tend to only muffle the room. It cut the bulk of ceiling fan hum and general household noise during testing without the muffled pressure sensation that cheaper ANC tends to introduce.

Call quality is the other half of the noise story, and the six microphones per pair do real work here. Walking through a home environment with a ceiling fan running and a window open, callers reported clear voice pickup without the typical compressed, distant quality of budget earbud microphones. OnePlus claims voice clarity holds at wind speeds up to 25 km/h, a figure sourced from the company’s own testing. The microphones do enough of the heavy lifting that you don’t have to repeat yourself or raise your voice to be heard on a normal call.

For gaming, OnePlus cites a 47ms low-latency mode that cuts audio delay during BGMI, FreeFire, and Call of Duty sessions. Whether or not that exact figure holds in real-world conditions, the gaming mode made footsteps and directional cues noticeably easier to track in casual mobile matches. The 3D Spatial Audio mode is distinct from the Game Sound Spatial Audio mode, and the two stack on top of each other when activated through the HeyMelody app. Outside of gaming, the standard transparency pass-through works well enough for quick conversations and station announcements without removing the buds. It does the job at this price without reaching class-leading transparency levels.

A 54-Hour Battery Wrapped in a Pebble-Shaped Case

Over several days of mixed use, the Nord Buds 4 comfortably held a full workday plus the commute home without needing the case. OnePlus’s 54-hour figure is measured with ANC off and volume at 50 percent in AAC mode, per the company’s own testing on the OnePlus India launch page. At max volume with ANC engaged, expect a real-world number in the neighbourhood of 20 hours of total playback, based on the battery drop observed during continuous testing.

Built to last 54-hour ultra-long battery life means less time chasing your case and more time pressing play all day

OnePlus’s launch copy positions the 54-hour figure with the caveat that it is measured in AAC mode with ANC off and volume at 50 percent, per the company’s own testing on the OnePlus India launch page. A 10-minute top-up in the case returns around 11 hours of listening time, a fast-charge figure that makes the earbuds practical for weekend trips without the cable. The case itself feels more solid than the price suggests, with a weighted hinge that snaps shut cleanly. The pebble-shaped finish does pick up scratches easily in a jeans pocket, a tradeoff to be aware of if you carry the case loose rather than in a separate pouch.

OnePlus’s launch copy describes each bud as ‘an ultra-light 4.3g with an ergonomic design for a barely-there feel,’ positioning the buds against heavier fitness-focused rivals. That weight pays off in fit: the buds sit in the ear without the pressure or fatigue that some heavier budget options produce, and they stayed secure during desk work and casual walks. The IP55 rating covers dust ingress and water jets but not full submersion, which matters less for gym sessions and commutes than for any actual swimming. Compared with the IPX4 ratings common at this price, the extra water-jet protection is a meaningful upgrade, as Trusted Reviews explains in its breakdown of what an IP55 rating covers. Two colour options are available at launch: Stellar Black and Astral Teal.

The fast-charge figure, the lightweight fit, and the IP55 rating together push the Nord Buds 4 out of the casual-use category and into the gym-and-commute category without a price bump. The scratch-prone finish is the one build choice OnePlus made that gives the case away as a budget product. Buyers who carry the case loose in a jeans pocket will see wear within weeks; buyers who use a separate pouch should get months of clean use.

The HeyMelody App and the Software Hooks

The Nord Buds 4 pair with OnePlus’s HeyMelody companion app, or integrate directly into the Bluetooth settings on OnePlus phones. The app gives quick access to the equaliser, the Bass mode toggle, the touch-control customisation, and the ANC mode selector, without burying those controls under multiple sub-menus. On a OnePlus handset running OxygenOS 12.0 and above, the Game Sound Spatial Audio mode shows up in the Earbuds Function inside Bluetooth settings without needing the HeyMelody app at all. For non-OnePlus users, HeyMelody is available on both the Google Play Store and the iOS App Store. The app itself stays clean and avoids the visual clutter that many audio companion apps pile on.

• Bluetooth 6.1 for the wireless connection
• Dual Device Connection for two simultaneous pairings
• Google Fast Pair and Microsoft Swift Pair for quick setup
• AI Translate and AI Assistant integration on compatible phones
• 250m wireless range under ideal conditions

OnePlus ships Game Sound Spatial Audio for BGMI, FreeFire, and Call of Duty through both the HeyMelody app and the OxygenOS 12.0 and above Earbuds Function on OnePlus phones. The 47ms Gaming Mode cuts audio delay during mobile matches, making directional cues easier to track in casual play. None of these add to the bottom-line price, which is part of why the Nord Buds 4 reset the bar for what Rs 3,299 should buy.

OnePlus’s positioning of the Nord Buds 4 sits alongside the upcoming N6 smartphone launch on June 30, 2026, as part of a broader push toward more affordable N-series devices in India. The brand’s recent product strategy in the country has leaned heavily on the Nord lineup after the company shelved its compact flagship ambitions. The Nord Buds 4 is the audio counterpart of that strategy: premium-tier specs sold through a budget-tier price. The result is a pair of earbuds that compete on the spec sheet with options costing significantly more.

Where the Nord Buds 4 Sits at Rs 3,299

The Nord Buds 4 went on sale in India from June 29, 2026, with a limited-period introductory price that sits below the standard Rs 3,299 sticker. At that price, the Nord Buds 4 are in direct competition with budget picks from Realme, Redmi, and boAt. The active noise cancellation, the battery life claim, and the IP rating are unusual at this tier, putting the Nord Buds 4 ahead of most rivals on paper. The default tuning, the gaming mode, and the 47ms low-latency audio are also rare to find together at this price point. Two colour options and a wide range of retail channels give buyers flexibility on the buying decision.

• Stellar Black and Astral Teal colour options at launch
• Available through OnePlus’s official store, Amazon, Flipkart, Blinkit, Myntra, and select retail partner outlets
• Rs 3,299 standard price, Rs 3,099 limited-period introductory
• General sale from June 29, 2026 in India

The Nord Buds 4 are an easy pick for buyers who care about the spec sheet as much as the listening experience. Listeners who prioritize a flat, balanced default tuning over heavy bass will find the sound profile unusual at this price. Buyers who want flagship-tier ANC and gaming features without the flagship-tier price will get what they came for, with the tradeoffs concentrated in treble harshness on certain tracks and the scratch-prone case finish. The Nord Buds 4 set the new baseline for what sub-Rs 4,000 earbuds should deliver in 2026.
