Description

The OnePlus Buds Z2 are the successor to the Buds Z and offer a number of significant improvements, particularly in the area of noise cancellation. Despite a similar design, the earbuds have been optimized in many aspects.

Active Noise Cancellation and Sound

One of the main innovations in the Buds Z2 is the integrated **Active Noise Cancellation (ANC)**. This technology reduces ambient noise by up to 40 dB and offers two modes, “Faint” and “Extreme,” which can be chosen depending on the environment. For moments when you need to be aware of your surroundings, a **Transparency Mode** is available. The headphones are equipped with the same 11 mm dynamic drivers as the more expensive Buds Pro, which ensures a powerful sound with a strong bass.

Performance and Controls

The Buds Z2 support **Bluetooth 5.2**, which ensures a stable and energy-efficient connection. For gamers, the low latency of just 94 ms in Pro Gaming Mode is of particular interest, although this feature is mainly available in combination with select OnePlus smartphones. Control is handled via capacitive touch surfaces on the stems, which support gestures like tapping and holding to control music and calls. An automatic **wearing detection** feature pauses playback when an earbud is removed.

Battery Life and Design

The battery life of the Buds Z2 is impressive: with a single charge, the earbuds provide up to 7 hours of playback (without ANC), and the combination with the charging case extends the total runtime to up to 38 hours. Even with ANC activated, they still offer up to 27 hours of total runtime. The charging case is charged via **USB-C** and supports a fast charging feature that provides enough power for up to 5 hours of playback in just 10 minutes. The earbuds are IP55-rated for dust and water resistance, making them an ideal companion for sports and daily use.
