The Quick Verdict
The OnePlus Nord Buds 4 Pro is a feature-packed mid-range TWS that brings Bluetooth 6.0, 55dB ANC, LHDC 5.0 Hi-Res Audio, and a 54-hour battery to the sub-₹4,000 segment. It's the most technically advanced OnePlus TWS in the Nord lineup, with volume swipe controls, wear detection, and AI translation. However, the bass-heavy tuning and single-driver setup lag behind the dual-driver Realme Buds Air 8. For OnePlus loyalists and bass enthusiasts, it's a solid buy. For balanced sound seekers, the Realme Air 8 is the better value.
The Good
1. Bluetooth 6.0 — First in Segment
The only TWS under ₹4,000 with Bluetooth 6.0. This means better stability, lower latency, and improved power efficiency compared to 5.4. Future-proofing at a budget price.
2. 55dB TÜV-Certified ANC
The strongest ANC in the Nord lineup. It effectively reduces AC hum, traffic noise, and metro rattle. The adaptive AI mode adjusts strength based on environment, and the TÜV certification adds credibility.
3. Volume Swipe Controls
Slide up/down on the stem to adjust volume — a genuinely useful feature that competitors like Realme Air 8 lack. Once you get used to it, tap-only controls feel primitive.
4. Insane Fast Charging
10 minutes of charging delivers 13 hours of playback — the best in this comparison. The Realme Air 8 manages 11 hours from the same 10-minute charge.
5. 54-Hour Battery Life
With ANC off, total battery reaches 54 hours. Real-world testing confirms ~33 hours with mixed ANC and LHDC usage — still excellent for the segment.
6. Wear Detection & Spotify Tap
Auto-pause when removing an earbud, and instant Spotify launch with a long press. Premium features at a budget price.
The Bad
1. Single Driver vs. Dual Driver Competitors
The 12mm titanium driver is good, but the Realme Buds Air 8's 11mm + 6mm dual driver setup with dual DAC delivers superior sound separation and clarity. OnePlus missed an opportunity here.
2. Bass-Heavy Tuning Masks Mids
Like previous Nord Buds, the tuning is bass-forward. EDM and hip-hop sound fantastic, but vocals and mid-range instruments lack detail. The Realme Air 8 and CMF Buds Pro 2 sound more balanced.
3. No LDAC — Only LHDC 5.0
The Realme Air 8 supports both LHDC 5.0 and LDAC, giving broader Hi-Res compatibility. OnePlus limits you to LHDC 5.0, which isn't supported by all devices.
4. AI Translation Is Limited
Only 4 languages, and only works on OnePlus phones. The Realme Air 8 supports 30+ languages and works across devices.
5. Cheap Ear Tips
The included silicone tips feel plasticky and don't create a great seal. Upgrading to aftermarket tips improves comfort and ANC performance.
6. Matte Texture Feels Cheap on Earbuds
While the case's matte finish is premium, the earbuds themselves feel plasticky and unpleasant in the ear after extended wear.
Who Should Buy?
| Buy If | Skip If |
|---|
| You want the latest Bluetooth 6.0 | You want dual-driver sound quality |
| You love bass-heavy music | You need balanced, audiophile-grade sound |
| You value volume swipe controls | You want LDAC codec support |
| You're a OnePlus ecosystem user | You need broad AI translation support |
| You want the fastest charging in the segment | You want the best overall value (Realme Air 8) |
Bottom Line
The OnePlus Nord Buds 4 Pro is a technically impressive TWS that leads in connectivity (Bluetooth 6.0), charging speed, and ANC certification. But the single-driver setup and bass-heavy tuning hold it back from being the best under ₹4,000. For OnePlus fans who prioritize features over pure sound quality, it's a solid choice. For everyone else, the Realme Buds Air 8 offers better value.
Rating: 3.75/5 — Best Bluetooth 6.0 TWS under ₹4,000. Outshined by Realme Air 8 for sound quality and value.
