Product Information

The high-end is disappointing. There simply isn't enough energy at the top end to balance out the sound, which especially makes the overall sound signature dark, muddy, and lopsided. The ANC data comes from the OnePlus test laboratory. Actual performance will vary depending on user customization and environmental conditions.

OnePlus claims a latency of minimum 94ms when paired with select OnePlus phones, although it fails to mention which exact OnePlus phones, how the headset achieves this lower latency, and what the latency is with other devices. Latency can be reduced to as low as 94 ms when paired with select OnePlus phone devices, with Pro Gaming mode turned on. Any changes you make in the app get saved on the earbuds, which means they get carried over to the next device, even if the device is something like a PC that does not support the app. Performance There is also a Bass preset, which sounds like the Balanced preset but with even more bass, in case you have hearing loss (or desire to get it). The headphones are certificated for IP55 dust and water resistant. Please avoid using the headphones during strenuous exercise or while in humid environments. Water damage is not covered under warranty. Sweat resistance follows the same principle as water resistance because the headphones can help prevent liquid, including sweat, from entering inside. We also applied special processing to the innards in prep to enhance sweat resistance capability. However, sweat resistance capability will decrease with long-term use. Sweat damage is not covered under warranty.The Bullets Wireless Z2 ANC feature 12.4mm titanium-coated dynamic drivers. The earbuds support SBC and AAC codecs over a Bluetooth 5.2 connection. The Bullets Wireless Z2 do not have a dedicated companion software. On OnePlus phones, you do get a dedicated info screen for them but there's nothing here to adjust. Also, even though you can see the firmware version here, there isn't any way to actually update it. The larger 12.4mm drivers are a major differentiator between the OnePlus Bullets Wireless Z2 and the Bullets Wireless Z, and this has made a positive difference to the sound quality. The sonic signature in particular sees some changes, with the Bullets Wireless Z2 sounding a bit more punchy and driven, while maintaining the reasonable level of detail and clarity that the original Bullets Wireless Z introduced to the budget audio category in 2020.

A 10-minute charge keeps your music going for 5 hours. (5 hours of battery life is measured based on combination of earbuds and the case, with ANC mode turned on. A single 10-minute charge of the earbuds themselves delivers 2 hours of playtime only. Charging and battery test results are based on internal OnePlus laboratory results (25° C or 77° F). Test date: June 7, 2021. Fast charge your OnePlus Buds Z2 using a standard adapter or Type-C USB charging cable. Requires 5V~1.5A adapter or higher. Actual performance experienced by users may vary based on the specific charging environment conditions. In terms of technical performance, Bullets Wireless Z2 have a moderate level of resolution and detail in the sound. This usually comes down to the choice of drivers used rather than the codec, although a higher bit rate codec couldn't have hurt. Imaging and soundstaging were unobjectionable and offered some space and directionality to the sound that made the overall presentation pleasant to listen to. The microphone performance on the Bullets Wireless Z2 is good. There is audible compression when speaking even in quiet environments but voices still sound relatively clear with good tonality. In noisier environments, the AI scene-model algorithm does a good job of reducing ambient sounds and prioritizing the voice, which sounds fairly similar to speaking in quiet environments.OnePlus Bullets Wireless Z2 has 16 hours of talk time and with a standby time of 80 hours on a single charge. Endurance test data is based on OnePlus laboratory tests conducted at 50% volume. Specific endurance performance will vary based on actual conditions and is affected by volume, output source, environmental interference, product features, software versions and usage habits. The new ANC mode on the Bullets Wireless Z2 ANC also worked reasonably well. It does its best with low-frequency sounds, so things like the sound of an aircraft or bus engine, while also being decent for household sounds such as air conditioners and fans. It doesn't do so well with mid and high-frequency sounds but that's generally the domain for bigger and more expensive headphones. During my testing, the latency performance was good for watching videos as the delay was barely noticeable when paired with an iPhone. Latency on Android was notably higher when using AAC and the audio also took longer to sync when unpausing or skipping but was fine when using SBC. On OnePlus phones, the earbud functions can be controlled directly through the Bluetooth settings without having to install a separate app. The Bullets Wireless Z2 has exceptional battery life. During my battery drain test, the headset ran continuously for 28.5 hours, which is very close to the 30 hours claimed by OnePlus. After a ten-minute charge, the headset went on for 20.4 hours, which is just over the 20 hours claimed by the company. With normal use, the headset should last well over a week on a single charge.
