Design Build and Comfort
Lightweight and Ergonomic
The OnePlus Bullets Wireless Z3 Earphone is very light, weighing around 26 grams. The neckband is made of soft, flexible silicone that doesn’t feel stiff or heavy on your neck. This makes it perfect for long commutes, workouts and gym sessions, and all-day listening while working or studying.
The in-ear buds fit securely and don’t easily slip out, even when you’re moving around.
Magnetic Earbuds and Controls
One of the classic neckband features that still works beautifully is the magnetic earbuds. When you join the buds in front of your chest, music auto-pauses. When you separate them again, playback resumes. This is super handy if you often pause music to talk to someone or check a message.
Controls are handled via physical buttons on the neckband:
- Play/pause
- Volume up/down
- Next/previous track
- Call answer/reject
- Voice assistant shortcut
The buttons are simple, tactile, and easy to use even while wearing gloves or during a workout.
IP55 Dust and Water Resistance
The OnePlus Bullets Wireless Z3 Earphone comes with an IP55 rating, which means it’s dust-resistant, can handle sweat and light splashes, and is safe for gym use and monsoon commuting. It’s not fully waterproof, so you shouldn’t submerge it in water, but for daily Indian conditions, IP55 is a solid durability feature.
Sound Quality and Audio Features
Strong Bass with 12.4 mm Drivers
The OnePlus Bullets Wireless Z3 Earphone uses 12.4 mm dynamic drivers with OnePlus’s BassWave algorithm. This gives:
Punchy, thumping bass.
Clear midtones for vocals.
Crisp highs that don’t feel too sharp.
For the price, the bass is one of the standout features. It works really well with Bollywood and Punjabi tracks, EDM and hip-hop, and casual gaming and action movies. You won’t get studio-level neutrality, but for a budget neckband, the sound is very enjoyable and energetic.
3D Spatial Audio Support
The OnePlus Bullets Wireless Z3 Earphone supports 3D Spatial Audio on compatible devices. This creates a more immersive listening experience, especially for movies, action content, and some music tracks that support spatial audio. It works best with Android devices that support this feature, giving a wider, more “surround-like” sound.
Codecs and Compatibility
The OnePlus Bullets Wireless Z3 Earphone supports SBC and AAC codecs and works well with Android and iOS. For most users, audio quality over Bluetooth is stable and satisfying, with no noticeable lag in daily use.
Call Quality and AI ENC
One of the key upgrades in the Z3 is AI-powered Environmental Noise Cancellation (ENC) for calls.
In real-world use, background noise like traffic, crowds, and fans is reduced, and your voice comes out clearer on the other end. It’s good enough for office calls, casual work meetings, and personal conversations.
However, it’s not flagship-level. In very noisy environments, some noise might still leak through. For most everyday scenarios in India, though, call quality is decent to good, especially at this price.
Battery Life and Charging: The Real Star
Massive Endurance
Battery life is where the Bullets Wireless Z3 truly shines:
Up to 36 hours of music playback at around 50% volume
Up to 21 hours of continuous call time
This means you can use it for days without charging, and it’s ideal for students, travelers, and people who forget to charge devices regularly.
Super Fast Charging
OnePlus has added a very useful fast-charging feature: 10 minutes of charging gives up to 27 hours of playback. This is perfect if you often run out of battery, need a quick top-up before heading out, or don’t like waiting for long charging times.
The neckband uses a USB Type-C port, which is convenient since most modern phones and chargers already support it.
Connectivity and Smart Features
Bluetooth 5.4 and Fast Pair
The OnePlus Bullets Wireless Z3 Earphone uses Bluetooth 5.4, which offers a stable connection, lower latency, and better power efficiency. It also supports Google Fast Pair, so when you’re using an Android phone, pairing is quick and automatic, and you can reconnect easily without going through settings manually.
Voice Assistant Shortcut
There are a dedicated button to trigger your voice assistant (Google Assistant on Android, Siri on iOS). This makes it easy to set reminders, ask questions, or control music without touching your phone.

Performance in Real Scenarios
For Workouts and Gym
IP55 rating handles sweat and light rain, the lightweight design doesn’t feel heavy during movement, and the secure fit means buds don’t fall out easily. Great for running, cycling, weight training, and cardio.
For Commute and Daily Travel
Long battery means you don’t charge often, fast charging helps if you forget to charge overnight, and good bass and clear sound make it perfect for music, podcasts, and videos. Perfect for daily bus, train, or metro commutes.
For Office and Study
Comfortable for long listening sessions, ENC helps during calls in noisy offices or crowded areas, and simple buttons are easier than touch controls when you’re focused. Good for remote work, online classes, and study sessions.
For Gaming
Bass-heavy tuning works well for mobile games, Bluetooth 5.4 gives relatively low latency, and the secure fit is helpful during long gaming sessions. Ideal for casual gaming like COD Mobile, PUBG, Genshin, etc.
