OnePlus Buds 4 with dual drivers, powerful ANC, and long battery life

OnePlus changed things up with the Buds 4. The case is round now instead of rectangular — fits in your pocket better. But the real story is inside. They packed in dual drivers (an 11mm woofer and a 6mm tweeter), each with its own DAC. That’s the sort of setup you usually see on much pricier earbuds. The result? Sound separation is genuinely good. Bass hits hard but doesn’t drown everything else.

The noise cancellation is what surprised me though. OnePlus claims up to 55dB of adaptive ANC, and it adjusts 800 times per second based on your surroundings. It’s noticeably better than the Buds 3 — especially at blocking out voices in cafes or offices. Three mics with an AI algorithm handle calls, filtering out wind and background noise pretty well. Some flagship earbuds don’t do this cleanly.

Battery life depends on how you use them. With ANC off, you get around 11 hours from the buds and 45 hours total with the case. With ANC on, that drops to about 6 hours on the buds and 24 hours total. A 10-minute charge gives you roughly 11 hours of playback (case included), which is handy when you’re in a hurry. They’re IP55 rated too — fine for sweat and light rain, but the case isn’t water resistant. Touch controls work fine, though some people find them a bit sensitive. If you have a OnePlus phone, you get extras like LHDC 5.0 support and AI translation. For everyone else, the HeyMelody app unlocks most features.

💬 Frequently Asked Questions (Example)

Q: Will these work with my Samsung phone?

A: Yes, OnePlus Buds 4 are compatible with most Android phones (Android 8.0+). While they pair with any Bluetooth device, features like LHDC 5.0 and the AI translation tool are exclusive to OnePlus phones.

Q: Can I use just one earbud at a time?

A: Yes, each bud has its own chip. You can use the left or right bud independently for calls or music without needing the other one near you.

Q: Does the charging case support wireless charging?

A: The case charges via USB-C only. No wireless charging on this model, but it charges fast — 10 minutes gives you around 11 hours of playback (with the case’s help).

Q: How well do they handle sweat during workouts?

A: The earbuds are IP55 rated, so they can handle sweat and light rain without issues. But keep the charging case dry — it’s not water resistant at all.
