OnePlus Bullets Wireless Z2 Review

OnePlus Bullets Wireless Z2 Review: A Neckband That Still Makes Sense

While true wireless earbuds dominate store shelves, neckband headphones continue to serve listeners who prefer all-day comfort, secure fit, and fewer chances of losing an earbud. The OnePlus Bullets Wireless Z2 is built exactly for that audience. Released as an upgrade to the popular Bullets Wireless Z, it offers larger drivers, stronger battery life, IP55 protection, and a lightweight design that makes it easy to wear for hours.

The neckband format may feel old-fashioned to some buyers, but it has practical advantages. The buds connect to each other through a flexible neckband, so you can let them hang around your neck when not in use instead of placing them in a case. For commuters, gym users, and people who take frequent calls, that convenience can matter more than the latest trend.

Design, Comfort, and Build

The Bullets Wireless Z2 uses a slim, matte-finished neckband that looks modern and avoids the cheap plastic feel common in budget neckbands. At only 26.65 grams, it is light enough that you may forget you are wearing it after a few minutes. The OnePlus logo sits on the left side, while the right side houses the volume rocker, pairing button, and LED indicator.

Soft in-ear tips are included in multiple sizes, helping users find a comfortable seal. The buttons are clicky and well placed, making it easy to control music and calls without looking. The neckband comes in Magico Black and Beam Blue, both with red button accents that add a sporty touch. Although the construction is mostly plastic, it feels durable and reliable rather than fragile.

IP55 water and sweat resistance adds confidence for workouts and outdoor use. It can handle sweat and light splashes, but it is not suitable for swimming or submersion. For most fitness and commuting scenarios, that level of protection is sufficient.

Sound Quality and Audio Tuning

The biggest upgrade is the move to 12.4mm dynamic drivers, up from the 9.2mm drivers in the previous model. The larger drivers deliver a richer, more immersive sound with stronger bass presence. Hip-hop, electronic music, and action movie soundtracks benefit from the added low-end energy, and sound imaging is detailed enough to satisfy listeners who enjoy layered tracks.

The tuning emphasizes bass and treble, which makes music feel exciting but can sometimes overshadow vocals. Listeners who prioritize vocal clarity may find the presentation a little bass-heavy. OnePlus includes anti-distortion audio technology to keep playback clean at higher volumes, and in practice the earphones handle loud listening without obvious harshness.

Codecs and Audio Limitations

The Bullets Wireless Z2 supports SBC and AAC codecs. Both are serviceable for everyday listening, with SBC performing slightly better in sync during track changes and AAC offering familiar compatibility. The main omission is the lack of aptX or LDAC, which higher-end Bluetooth audio fans may miss. For the target price and audience, however, the included codecs are acceptable.

Latency, Gaming, and Calls

For media consumption, latency is not a major issue. On OnePlus devices, minimum latency is around 94ms, and watching movies or YouTube on an iPhone feels smooth. On other Android devices using AAC, sync can take slightly longer, while SBC performs better for play and pause responsiveness.

Gaming is the weak point. There is no dedicated low-latency mode, so competitive mobile games such as PUBG Mobile or Call of Duty Mobile will not feel as responsive as with gaming-focused earbuds. Casual gaming is fine, but serious players should look elsewhere.

Call quality is reliable. Bluetooth 5.0 provides stable connectivity, and the microphone captures voices clearly enough for work calls and personal conversations. It is not studio-grade, but it avoids the muffled or distant sound that plagues many budget headsets.

Controls and Connectivity

The three-button control scheme is intuitive. The middle button handles play, pause, call answering, and pairing mode, while the side buttons manage volume. Double and triple presses skip tracks, reducing the need to touch your phone. OnePlus users benefit from fast pairing, with the neckband appearing quickly on compatible devices. Non-OnePlus users can enter pairing mode with a long press of the middle button.

Battery Life and Fast Charging

Battery life is one of the strongest selling points. The 220 mAh battery is rated for up to 30 hours of playback at 50 percent volume. Real-world usage at higher volumes will reduce that figure, but it still comfortably outlasts many rivals. USB-C charging is included, and the fast charging claim is impressive: ten minutes of charging provides up to 20 hours of playback. That kind of top-up speed is genuinely useful for busy users.

How It Compares

Against the Samsung Level U2, the Bullets Wireless Z2 is lighter and offers longer battery life with faster charging, though both share Bluetooth 5.0. Against Xiaomi’s Mi neckband options, the OnePlus model loses some codec advantage if the rival supports aptX, but it fights back with faster charging and a more polished everyday experience. Overall, the Z2 competes well on comfort, battery, and value.

Verdict

The absence of aptX or LDAC and the lack of a low-latency gaming mode are real limitations, but they do not erase the overall value. If you want a budget-friendly neckband with long endurance and solid everyday performance, this model remains easy to recommend.
