OnePlus Bullets Wireless Z3 Review: Everything to Know
OnePlus has returned to the neckband market with a fresh update—the OnePlus Bullets Wireless Z3. We spent a full week using these earphones across different scenarios, including workouts, work calls, commutes, and entertainment. After extensive testing, we found the Z3 to be a strong upgrade in some key areas while staying true to its budget-friendly identity.
Launched in June 2025 at ₹1,699, the Bullets Wireless Z3 builds on the strengths of its predecessors and adds new features like Bluetooth 5.4, spatial audio, and longer battery life. At this price point, OnePlus aims to capture users who want reliable performance without paying for luxury branding or unnecessary extras.
Design and Comfort: Lightweight and Discreet
From the moment we wore the Z3, we noticed how light it felt. The neckband weighs just 26 grams, making it nearly unnoticeable after a few minutes. OnePlus stuck with a classic silicone-coated neckband design, but added subtle texture improvements for a more premium feel. The matte finish keeps it professional and clean.
During our testing, we wore the neckband for hours without discomfort. Whether we used it at the gym, on a hot commute, or while working at our desk, the neckband remained stable and didn’t irritate the skin. Its IP55 rating offered confidence during sweaty workouts and drizzly weather. The ear tips formed a decent seal and blocked out environmental noise passively.
Controls and Connectivity: Seamless and Smart
OnePlus placed three physical buttons on the left module—volume up, volume down, and a multi-function button that handles play/pause, call management, and voice assistant triggers. The tactile feedback felt responsive. The neckband also features USB-C charging, although OnePlus did not include a cable in the box to keep costs down.
Bluetooth 5.4 made pairing smooth and reliable. We connected the Z3 to our Android phone in under three seconds using Google Fast Pair. Once paired, switching between devices worked flawlessly. We didn’t experience any dropouts during testing, even while walking around with the phone in a pocket or bag. The 10-meter range also held up during office and home use.
Audio Quality: Bass-Heavy Sound with Spatial Flair
We tested the Z3 with music, movies, and podcasts. OnePlus fitted these earphones with large 12.4 mm dynamic drivers, which delivered thumping bass right out of the box. The sound leaned heavily into low frequencies. Bass lovers will enjoy this signature. However, we noticed that mids and vocals sometimes got overshadowed.
OnePlus added three sound profiles—Balanced, Bold, and Bass. The Balanced mode gave us the most well-rounded performance, but switching to Bold sharpened vocal clarity. The Bass profile, as expected, intensified the low-end even further.
The Z3 also supports 3D spatial audio, which added a noticeable sense of width and depth to stereo tracks. During movies and games, this feature enhanced immersion without sounding artificial. Audiophiles may find the tuning too colored, but casual users will likely appreciate the impactful sound.
Call Quality: Effective Noise Reduction for Voice Clarity
OnePlus introduced AI-powered Environmental Noise Cancellation (ENC) to improve call quality on the Z3. We tested this feature during outdoor walks, in cafés, and near traffic. Background sounds like wind, chatter, and honks faded into the background, and our voice stayed clear on the receiving end.
Callers told us they could hear us clearly even when we stood on busy roads. The neckband’s microphones handled noisy environments better than expected. For professionals who take frequent calls or students attending online classes, this earphone delivers dependable call performance.
Battery Life: A Marathon Runner
Battery life is where the Z3 truly stands out. OnePlus claims up to 36 hours of playback on a full charge and 27 hours from just 10 minutes of charging. During our tests, we got 33 to 34 hours of real-world usage with music streaming, occasional calls, and YouTube playback at around 50-60% volume.
The USB-C fast charging impressed us. A 10-minute charge gave us over a day’s worth of playback, making it perfect for users in a hurry. We charged it once during the entire week and never worried about running out of juice.
What’s Missing: Some Modern Features Skipped
OnePlus focused on essentials but skipped some modern features that competitors now offer, even at similar prices. Active Noise Cancellation (ANC) is missing, which may disappoint users looking for total isolation. Also, the Z3 doesn’t support multipoint connection, so we couldn’t connect it to a phone and laptop simultaneously.
The cable, while durable, lacks braiding, and the available codecs remain limited to SBC and AAC. For serious audio work or high-definition streaming, this could become a limitation. Still, considering the price, these omissions didn’t break the overall experience.
Price and Competition: Strong Value with Minor Trade-offs
At ₹1,699, the OnePlus Bullets Wireless Z3 undercuts many of its rivals and even its predecessor, the Z2 ANC. With significant upgrades in battery life and audio tuning, the Z3 justifies its cost well. However, if someone wants Active Noise Cancellation, the Z2 ANC—priced only a few hundred rupees more—might make a better option.
The Z3 competes with budget neckbands from Realme, boAt, and Noise. In our testing, it outperformed most of them in build quality, battery, and call clarity. It may not win on raw features alone, but the consistency of the overall package gives it an edge.
Final Verdict: Ideal for Daily Use and Bass Lovers
After a week of intense usage, we came away impressed with the OnePlus Bullets Wireless Z3. This neckband focuses on the essentials and delivers them well. It doesn’t try to chase trends or offer flashy gimmicks. Instead, it provides excellent battery life, reliable connectivity, solid call quality, and deep, bass-heavy audio—all wrapped in a lightweight, durable form.
We recommend it for users who want dependable performance, especially those who listen to music and take frequent calls throughout the day. Gym-goers, students, and working professionals will find plenty to like here.
However, users looking for top-tier audio fidelity, ANC, or high-end features may need to look higher up the price ladder. For everyone else, the Z3 offers one of the best budget neckband experiences available in 2025.
Pros:
- Lightweight and comfortable for long hours
- Excellent battery life with fast charging
- Punchy bass and enjoyable sound
- Clear call quality with noise reduction
- Strong value for the price
Cons:

Final Rating: 4.2 / 5
OnePlus built the Bullets Wireless Z3 for everyday users, and it delivers exactly what it promises. For under ₹2,000, it’s a neckband that punches above its weight.
