OnePlus rolls out the Nord Buds 4 Pro, positioning them as the most premium option in its budget earbud range while still undercutting the flagship Pro series. Priced at INR 3,999 (about $42), the pair packs active‑noise cancellation, high‑resolution audio, touch controls and AI translation. They arrive in Radiant Gray or Raven Black with a stylish matte‑finished compact case that opens from the top.

The 12 mm titanium‑coated drivers claim 100 % more power than the previous Nord Buds 3 Pro, delivering a balanced soundstage that emphasizes mids and smooth highs while keeping bass assertive but controlled. Bluetooth 6.0 supports SBC, AAC and LHDC codecs, and the HeyMelody app lets users toggle ANC levels, enable a 24‑bit/96 kHz Hi‑Res mode, and activate game‑mode low latency for competitive wireless gaming sessions today.

Microphone performance holds up in quiet rooms, while the three‑tier ANC system claims up to 55dB reduction but feels uneven, with the high preset injecting noticeable high‑frequency hiss in moderate noise. IP55 protection shields the earbuds from dust and splashes, though the charging case lacks any rating. Overall, the Nord Buds 4 Pro deliver surprisingly refined audio for a sub‑$50 price point.
