OnePlus Buds 4 - Green

Does it have active noise cancellation?

Yes, the OnePlus Buds 4 include active noise cancellation (ANC) with three adjustable modes. The technology can reduce ambient noise by up to 48 dB, ideal for travel, work, or workouts. You can switch between maximum, adaptive, or off modes depending on the scenario.

How long does the battery last per charge?

A full charge offers up to 13 hours of continuous playback with ANC off. With ANC active, the duration is reduced to approximately 10 hours. The charging case provides up to 44 hours of total autonomy, allowing for several complete cycles without needing a nearby charger.

Does it have wireless charging?

Yes, the Buds 4 support wireless charging. The Qi-compatible case allows you to recharge wirelessly on any certified charger. You can also use the included USB-C cable for fast and traditional charging when needed.

Water and sweat resistance?

The OnePlus Buds 4 have an IP55 certification, ensuring protection against water and sweat. They are safe for intense workouts, running, or use on rainy days in Portugal. However, they are not suitable for prolonged immersion in water.

Does it work with Android and iPhone?

Fully compatible with both systems. The Buds 4 use standard Bluetooth 5.4, working perfectly with any Android smartphone or iPhone. Connectivity is immediate and does not require a dedicated app, although the OnePlus app offers additional customizations.

How do they compare to AirPods or Galaxy Buds?

The OnePlus Buds 4 offer better value for money: effective ANC, superior autonomy (44h total vs 30h for AirPods Pro), and wireless charging for less than €110. They fall short in ecosystem integration with iPhone and do not have automatic removal detection. For Android users, they represent a more competitive choice than Galaxy Buds+.
