- "52h / 43h battery" — both are ANC-off, case included. Realme with ANC + LHDC is ~5h per charge in real use.
- OnePlus "premium" sound — AAC/SBC only, no Hi-Res. Realme genuinely carries LHDC 5.0 here.

- Wear detection — not confirmed on either; OnePlus's sibling (3r) has none, so treat as likely absent.

Buy This If…→ Realme Buds Air 7 — you care about sound quality, use an LHDC-capable phone, and want the strongest ANC of the two.
→ OnePlus Nord Buds 3 — you want the lowest price, longest-term battery peace of mind, and a clean, reliable everyday pair.
Bottom LineThe Realme Buds Air 7 is the better audio product — Hi-Res LHDC and 52dB ANC genuinely lift it above budget norms, as long as your ears (and phone) can use them. The OnePlus Nord Buds 3 answers with a lower price, a real battery-health guarantee, and dependable basics, but 32dB ANC and AAC/SBC-only sound are hard ceilings. Neither is a mistake at ₹2k — pick sound or pick savings.
