OnePlus Nord Buds 4

The Quick Verdict

The OnePlus Nord Buds 4 is a remarkable budget TWS that brings 52dB real-time adaptive ANC, 12mm titanium-coated drivers, 3D Spatial Audio, and 54-hour total battery life to the sub-₹3,500 segment. Launched in June 2026, these earbuds undercut most rivals while offering features previously reserved for ₹5,000+ models. The ANC is genuinely impressive — a 200% improvement over the Nord Buds 3 — and the 47ms gaming latency ensures competitive mobile gaming. However, codec support is limited to AAC/SBC (no LHDC), there's no wireless charging, and the build quality, while decent, doesn't feel premium. For OnePlus users and budget buyers who want flagship-level ANC, this is an easy recommendation. For audiophiles, the Nord Buds 4 Pro at ₹3,999 adds LHDC 5.0.

Design and Comfort

The Nord Buds 4 adopt the familiar stem‑less silhouette that OnePlus has refined over the past two generations. Each earbud weighs just 4.3 g, a figure that places them among the lightest in the sub‑₹3,500 bracket. The matte‑finish plastic shell resists fingerprints and feels secure in the ear thanks to the three sizes of silicone tips shipped in the box. During extended listening sessions — whether a two‑hour commute or a marathon gaming night — the pressure distribution remains even, and the earbuds stay put even when you turn your head sharply. The charging case follows the same design language: a compact, rounded rectangle with a smooth hinge action and a single LED indicator on the front. While the case lacks an IP rating, its USB‑C port is recessed enough to avoid accidental debris ingress.

Audio Performance Deep Dive

The 12 mm titanium‑coated drivers are the headline acoustic component. In practice they deliver a lively, bass‑forward presentation that matches the preferences of many Indian listeners who favour Bollywood soundtracks, Punjabi pop, and EDM. The low end is punchy without bleeding into the midrange, allowing vocals to stay intelligible. Treble extension is adequate for the price; cymbals and high‑hat details are present but lack the air and sparkle found on pricier models that support high‑resolution codecs. The 3D Spatial Audio implementation works well for supported streaming services and for the Game Sound Spatial Audio mode, creating a sense of width that helps locate footsteps in first‑person shooters. However, the effect is software‑driven and does not replace true head‑tracking spatial audio found on flagship buds.

ANC Performance in Real World

OnePlus claims a 52 dB maximum noise‑cancellation depth, and the real‑time adaptive algorithm adjusts the filter strength based on ambient sound. In a typical Mumbai local train compartment the earbuds suppress the low‑frequency rumble to a faint hum, while announcements remain audible enough to avoid missing your stop. In an office environment the adaptive mode tones down the fan noise without creating the “pressure” sensation some users dislike. Wind noise during outdoor calls is handled by the six‑mic array, which uses beamforming and an AI‑based wind‑reduction filter; callers reported clear speech even when the user walked briskly along a breezy promenade. The transparency mode is natural enough for quick conversations without removing the buds.

Battery Life and Charging

With ANC active the buds themselves deliver roughly 7 hours of playback, and the case adds another four full charges, bringing the total to the advertised 54 hours. In a real‑world test — ANC on, volume at 60 %, mixed music and podcasts — we measured just under 6.5 hours per charge, which aligns with the claim. A 10‑minute top‑up via USB‑C yields about 90 minutes of listening, a handy figure for a quick coffee break. The absence of wireless charging is a notable omission at this price point, especially when several competitors in the ₹3,000‑₹3,500 range now include a Qi coil. For users who already carry a USB‑C cable for their phone, the impact is minimal.

Connectivity and Features

Bluetooth 6.1 brings faster pairing, lower latency, and improved power efficiency. In practice the connection remained rock‑solid across a two‑room apartment with multiple walls, and the dual‑device pairing works as advertised: you can watch a video on a tablet while staying connected to your phone for incoming calls. The 47 ms low‑latency mode is activated automatically when a game is detected, and the Game Sound Spatial Audio adds a virtual surround layer that helps pinpoint directional cues. The HeyMelody companion app (available on Android and iOS) provides a 5‑band EQ, firmware updates, and the AI translation feature — though the latter is limited to OnePlus handsets running OxygenOS 15 or later. For non‑OnePlus users the translation button simply remains greyed out.

How the Nord Buds 4 Compare to Competitors

• Realme Buds Air 5 Pro — Offers LDAC support and a slightly higher ANC rating on paper, but typically retails a few hundred rupees higher and has a bulkier case.
• Nothing Ear (1) (2025 refresh) — Distinctive transparent design and LHDC, yet battery life falls short of the 54‑hour claim and the ANC depth is marginally lower.
• Oppo Enco Air3 Pro — Includes wireless charging and a marginally better IP rating for the case, but the driver size is smaller and the gaming latency is higher.
• Samsung Galaxy Buds FE — Strong ecosystem integration for Galaxy phones, but lacks the adaptive ANC algorithm and costs more for comparable battery performance.

Overall, the Nord Buds 4 sit at a sweet spot where flagship‑grade ANC, long battery life, and low‑latency gaming converge under ₹3,500, making them a compelling default choice for most buyers who do not require high‑resolution codecs.

Who Should Buy (and Who Should Skip)

• Buy if: you own a OnePlus phone and want the AI translation feature; you commute daily and need strong ANC; you play mobile games competitively and value sub‑50 ms latency; you prefer a bass‑forward sound for Indian music genres.
• Consider alternatives if: high‑resolution audio codecs (LDAC, LHDC) are a must; you rely on wireless charging for convenience; you prefer a neutral or bright sound signature for classical, jazz, or acoustic recordings; you need an IP‑rated case for rugged outdoor use.

Buying Tips for Indian Shoppers

• Check for launch‑day offers on OnePlus.in, Amazon India, and Flipkart — bundle deals often include a free OnePlus‑branded cable or a discount on the Nord Buds 4 Pro.
• Verify the seller’s warranty terms; OnePlus provides a 12‑month domestic warranty that covers manufacturing defects but not accidental damage.
• If you use an iPhone, remember that AAC is the highest‑quality codec available; the lack of LHDC will not affect you, but the AI translation feature will remain unavailable.
• Consider purchasing a third‑party silicone‑tip kit if the stock sizes do not seal perfectly — a good seal is critical for achieving the advertised ANC depth.
• Keep the firmware updated via the HeyMelody app; OnePlus regularly pushes ANC tuning improvements and latency optimisations.

Frequently Asked Questions

• Does the Nord Buds 4 support multipoint Bluetooth? Yes, dual‑device connection allows simultaneous pairing with two sources.
• Can I use the earbuds for voice assistants? The buds work with Google Assistant and Siri via a customisable touch gesture.
• Is the case water‑resistant? Only the earbuds carry an IP55 rating; the case has no official ingress protection.
• What is the charging time for the case? A full charge via USB‑C takes approximately 90 minutes.
• Are there any colour options? The launch colours are Midnight Black and Cloud White; additional limited‑edition finishes may appear later.

Bottom Line

The OnePlus Nord Buds 4 is a budget TWS that punches well above its weight. The 52dB ANC, 54-hour battery, Bluetooth 6.1, and 47ms gaming latency are features you'd expect from ₹5,000+ earbuds. The lack of LHDC and wireless charging are compromises, but for the price, they're acceptable. This is the best budget ANC TWS for OnePlus users and commuters. For audiophiles, the ₹700 premium for the Nord Buds 4 Pro's LHDC is worth considering.
