OnePlus Nord Buds 4 Pro

With ANC and LHDC enabled at 50% volume, they last around 4.5 hours on a single charge. If both features are disabled, battery life is approximately 8.5 hours. The manufacturer’s claimed up to 54 hours with the case applies to use without noise cancellation, so with ANC running continuously, the headphones will need to be recharged noticeably more often.Source:SpecificationsExpert reviews

Volume is adjusted by swiping on the stem, so there’s no need to take out your phone. Other touch controls can be remapped in HeyMelody; the equalizer and other settings are also available there. Swiping is particularly convenient for frequent volume adjustments, as it does not require a series of repeated taps.Source:SpecificationsExpert reviews

Suitable for running and workouts: they fit securely in the ears, and no noticeable discomfort was reported during prolonged wear. The IP55 protection rating is designed to withstand sweat, dust, and light rain. The charging case has no water resistance, so it is best kept dry.Source:SpecificationsExpert reviews

ANC effectively removes steady background noise: the hum of an air conditioner, fan, and engine was reduced by approximately 80%. For home, office, and travel, this is enough to keep music from getting lost in the surrounding hum. Voices, car horns, and other sharp sounds will still be audible—the noise cancellation does not create complete silence.Source:SpecificationsExpert reviews

In gaming mode, the latency is low: 45 ms is claimed, and no noticeable desynchronization between the action and sound was observed in BGMI. The combination of Bluetooth 6.0 and low-latency mode should be sufficient for regular mobile games without switching to wired headphones.Source:SpecificationsExpert reviews

For calls, they perform well: voices come through clearly and naturally indoors, without needing to speak louder than usual. Outdoors, the three microphones in each earbud, together with ENC, noticeably reduce background noise, although the quality is merely good rather than as clear as in a quiet room.Source:SpecificationsExpert reviews

The sound is distinctly bass-heavy: the low end is powerful and punchy, but on complex tracks it can push the vocals back and mask some of the detail. This tuning works well for EDM, hip-hop, and other bass-heavy genres. Those who prefer a more balanced presentation should note that the midrange is not the most detailed, and the equalizer does not completely change the sound signature.Source:SpecificationsExpert reviews

No—the AI translation feature is available only on OnePlus smartphones and supports four languages. You shouldn’t count on it working on other phones, even if the HeyMelody app is installed. Therefore, the translator is more of an added capability for owners of compatible devices than a universal feature.Source:SpecificationsExpert reviews
