Design and Comfort

The Z3 sticks to a formula that has worked for OnePlus since 2020. It’s a flexible neckband with magnetic earbuds. They snap together and power off when not in use. At just 26g, it disappears around your neck during long wear.

The build is mostly plastic. The cable is standard, not braided. That’s fine at this price point. But it won’t feel premium next to OnePlus’s flagship audio gear.

One thing to flag before you buy: a USB-C charging cable is not included in the box. You’ll need to use one from your phone or another device.

Sound Quality and Bass

The 12.4mm drivers are tuned for impact, not nuance. Bass hits hard. The Z3 gets loud without distorting at most volumes. That makes it solid for commutes, workouts, or background music.

Push it to max volume, though, and clarity drops off. It’s most noticeable in busy mixes with a lot going on. The 4 EQ presets in the HeyMelody app help shape the sound somewhat. But this isn’t a pair built for critical listening.

Battery Life and Fast Charging

This is the Z3’s strongest selling point. OnePlus rates it at up to 36 hours of music playback and 21 hours of talk time. That’s genuinely long for a budget neckband.

Fast charging adds real convenience too. Just 10 minutes on the charger gets you roughly 27 hours of playback. A dead battery is rarely an issue, even if you only remember a quick top-up.

Call Quality

AI Call Noise Cancellation does meaningful work cutting background noise on calls. It’s a noticeable step up from older budget neckbands that struggle in traffic or windy conditions.

For a $40 product, call clarity is one of the more impressive parts of this package.

OnePlus Bullets Wireless Z3 vs Z2: What’s New?

Here’s what actually changed from the Z2:

Upgraded Bluetooth 5.3/5.4 with Google Fast Pair
Added 3D Spatial Audio and 4 EQ presets
Slightly longer battery life and faster charging
Identical design and build to the Z2

If you already own a Z2 — especially the Z2 ANC, which has better clarity — the upgrade isn’t essential. Coming from an older model or a different brand, the Z3 is a reasonable step up.
