A Personal Take After Weeks of Real-World Use
OnePlus Bullets Wireless Z2 Common Problems – Real Fixes You Can Actually Use
The OnePlus Bullets Wireless Z2 has become one of the most talked-about neckband earphones in India — and for good reason. They’re affordable, sound punchy (especially for bass lovers), and last super long on a single charge. But even great devices can have hiccups. In this post, we’ll cover the most common issues with the OnePlus Bullets Wireless Z2 and offer simple, real-world solutions anyone can follow.
But let’s be honest: no gadget is perfect. Not even these.
After using the Z2 for a few weeks and reading what other users had to say online, I noticed some common problems many people face. So instead of making you scroll forums at midnight, I decided to create this helpful guide. I’ll share real issues, easy fixes that worked for me, and smart tips that even a 6th grader could follow.
Let’s dive in.
Why People Love the OnePlus Bullets Z2
Before we go into the problems, let’s understand why so many people (me included!) bought these earphones:
- Big 12.4mm drivers = loud and bass-heavy sound
- Up to 30 hours of battery life (crazy good for the price!)
- 10-minute fast charge = 20 hours of playtime
- IP55-rated — can handle sweat and light rain
- Magnetic play/pause control
All these features under ₹2000? It’s a solid deal — no wonder it’s a bestseller.
The OnePlus Bullets Wireless Z2 delivers powerful bass with its large 12.4mm drivers, perfect for EDM, Bollywood, and bass lovers. A quick 10-minute charge gives up to 20 hours of playback, while a full charge lasts up to 30 hours.
With IP55 water and sweat resistance, it’s built for workouts and daily use. Magnetic earbuds make pausing and resuming music effortless, while low-latency mode keeps gaming and videos in sync. Plus, AI noise cancellation ensures clear calls even in noisy surroundings.
Common Problems with OnePlus Bullets Wireless Z2 — and How to Fix Them Without a Headache
1. One Side Isn’t Working — Or No Sound at All
Sometimes the left or right earbud goes silent. It happened to me after I dropped my bag too hard.
Why It Happens:
- Dirt inside the speaker mesh
- Poor Bluetooth connection
- Hardware issue (less common)
How I Fixed It:
- Gently brushed the earbud mesh with a soft, dry toothbrush
- Reset the neckband (hold power button for 10 seconds)
- Paired it with another phone to test
- Charged it fully — low battery can cause weird issues!
Extra Tip: Change the ear tips after cleaning. A better seal can fix volume balance!
“Left ear stopped a week in—turns out a quick reset and a toothbrush on the mesh fixed it.” – ★★★★☆ Amazon review
2. Bluetooth Disconnects or Lags
This one’s annoying when you’re on the move. The sound cuts out or lags.
Possible Causes:
- Too many Bluetooth signals nearby
- You’re too far from your phone
- Bugs in Bluetooth settings
What Helped Me:
- Kept the phone in my front pocket (back pocket = bad signal)
- Unpaired and re-paired the neckband
- Restarted both phone and neckband
- Turned off Bluetooth on other devices
Pro Tip: Z2 works smoother with OnePlus phones.
Quick-Fix Table:
Situation | Risk Level | Instant Fix |
---|---|---|
Phone in back pocket with jacket | High | Move phone to front pocket |
Two smartwatches connected | Medium | Disable extra Bluetooth |
Walking near Wi-Fi router | Low | Use 5 GHz Wi-Fi band |
3. Battery Life Isn’t 30 Hours?
You expected 30 hours, but it dies in 10? Let’s fix that.
What Could Be Wrong:
- Music too loud (above 80%)
- Battery aging
- Cheap or wrong charger used
What Worked:
- Used the original OnePlus charger or a high-quality USB-C charger
- Avoided charging it overnight
- Kept volume around 70%
- Let it fully die and then fully recharge once every few weeks
Battery Saver Checklist:
- Lower volume = longer playtime
- Use short, fast charges
- Update Bluetooth firmware on your phone
“I hit 25 hours by sticking to 70 % volume and 15‑minute turbo charges.” — Amazon review Amazon

4. Magnetic Controls Not Working?
This feature is cool — pause/play by snapping the buds together. But sometimes it just stops.
Try This:
- Make sure the magnets click together properly
- Reset the neckband
- Try using it with another device
If still broken, the magnets may have lost strength after a fall. Try putting a paper between the earbuds. If they don’t stick, you might need a warranty claim.
5. Mic Sounds Muffled on Calls
Call quality can go bad — people say you sound like you’re in a tunnel.
Could Be:
- Dust or sweat in the mic hole
- Noisy background
- Bluetooth lag
Easy Fixes:
- Clean mic gently with a toothpick or brush
- Move to a quieter place
- Try different apps (like WhatsApp, Telegram)
- Reconnect the neckband
Mic Trick: Rotate the neckband so the mic sits closer to your chin. It helped me reduce street noise.
“Call quality is too good after a 15‑minute charge—perfect for one‑hour meetings.” — Amazon buyer Amazon
6. Bonus Fixes – Lesser-Known Problems
Gaming Delay?
Even with low-latency mode, fast games (like PUBG or COD) may lag a bit — especially on non-OnePlus phones.
Tip: Lower the volume to reduce audio delay. I got better sync this way.
Not Charging?
If it’s not charging:
- Try a new USB-C cable and power brick
- Clean the charging port (lint can block it!)
- Let it charge for 20–30 minutes, then try turning it on
Deep Charge Trick: Plug into a fast charger, wait 20 minutes, hold the power button for 15 seconds — works if the battery went completely dead.
7. Neckband Not Turning On
Problem: You press the power button, but there’s no light or sound.
What to Do:
- Charge for at least 30 minutes and try again
- Try another Type-C cable
- Reset the neckband using button combo (Vol+ + Vol-)
If there’s still no response, the internal board may be damaged – only service can help here.
8. Volume Too Low Even at Max Setting
Problem: Even at full volume, sound is not loud
Fixes:
- Turn off any Volume Limiter in your phone’s settings
- Use the OnePlus Audio app (if available) and check for firmware updates
- Clear Bluetooth cache from phone settings
9. Buttons Not Working
Problem: Play/Pause or Volume buttons don’t respond
Causes:
- Water damage
- Loose internal connections
- Software lag
What You Can Try:
- Reset the neckband
- Wait a few minutes and try again after reconnecting
- If still not working, visit a OnePlus service center
10. Can’t Connect to Phone/Laptop
Problem: The neckband doesn’t show up in Bluetooth list
Quick Fix:
- Long-press the pairing button until LED blinks
- Forget and re-pair the device from Bluetooth settings
- Try it on a different phone/laptop to confirm
