OnePlus Bullets Wireless Z2 Bluetooth in Ear Earphones with mic, Bombastic Bass – 12.4 mm Drivers, 10 Mins Charge – 20 Hrs Music, 30 Hrs Battery Life, IP55 Dust & Water Resistant (Magico Black)

Product Information

The ANC data comes from the OnePlus test laboratory. Actual performance will vary depending on user customization and environmental conditions. 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. OnePlus Bullets Wireless Z2 has a battery life of 30 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 build quality and finish of the headset is very good. The rubber feels pliant and durable, and the plastics all have a quality feel. The rubber for the cables is also striated. The headset is also IP55 rated, so it can survive being splashed with water. Comfort 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. Conclusion The Bullets Wireless Z2 is a comfortable headset. The ear tips are made out of soft rubber and have the oval design found on the OnePlus Buds Pro and Buds Z2. They fit the ears well and can stay there for hours without being uncomfortable. To top it off, the treble performance is great as well. It shares some of the mellowness of the mid-range so there's no unwanted harshness or sibilance at the cost of some air and brilliance. However, it still comes across as detailed and articulate without being dark or muddy.

Finally, connectivity performance was stable with the Bullets Wireless Z2 ANC and there were no observed issues with connection quality or stability. Battery and charging Latency in applications was poor. Games and music apps demonstrated notable delay, with apps like piano players having almost half a second of latency after a key was pressed. As usual, I would recommend wired audio if latency is important to you or if you want to use the microphone while gaming.

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 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. 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.

Latency can be reduced to as low as 94 ms when paired with select OnePlus phone devices, with Pro Gaming mode turned on. The Bullets Wireless Z2 have relatively large 12.4mm drivers. They connect over Bluetooth 5.0 and support SBC and AAC codecs. 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 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.

The Bullets Wireless Z2 ANC does not have a lot of features so options are limited here. You can switch between ANC on, off, and transparency mode. You can flip between the four EQ presets and also make your own. And finally, you can do very basic customizations of the physical switches. On OnePlus phones, the earbud functions can be controlled directly through the Bluetooth settings without having to install a separate app.

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.IP55 rating and IPX4 rating achieved on test date: June 11, 2021. Data is based on test results using TÜV SÜD based on IEC 60529:1989, A1:1999 and A2:2013 test standards. Water and dust resistance may be reduced as the device ages. Liquid and dust damage are not covered under warranty. Switching ANC modes only has a small effect on the audio quality. The sound is ever so slightly brighter and less bass-heavy with ANC off compared to on, and then further slightly brighter with transparency mode enabled. 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.
