Now, let’s look more into the detailed  specifications of OnePlus Buds Z  below:

1. Design of OnePlus Buds Z

The OnePlus Buds Z earbuds have the signature OnePlus design that the company has used on all of its wireless audio products since the OnePlus Bullets Wireless 2. This includes an oblong shape that houses the drivers with a large, flat, circular back panel with a CD-like pattern that is also touch-sensitive. The speaker housing looks nearly identical to those on the Bullets Wireless 2/Z.

On the inside, the OnePlus Buds Z uses silicone ear-tips, which are very comfortable. Next to the ear-tip are the two contacts that charge the earbuds when they are inside the case, and also what looks like a pressure release port.

The area surrounding the ear-tip is touch-sensitive and is used to determine when the earbuds are inside your ears.

On the outside, the case is made out of hard, glossy plastic. On the front is an LED that glows red when the case is charging and green when it’s full. On the back is a USB-C port with a button for pairing and charging as well.

2. Comfort

The OnePlus Buds Z is a comfortable pair of earphones. The earbuds are extremely light and the in-ear design doesn’t put too much pressure on your ears and can be worn pretty much for the entire duration of their battery life without any fatigue or discomfort.

The earbuds also don’t stick out too much from the side of your head so users can wear them while lying on sides in the bed. Oneplus Buds Z  has ear-tips that can occasionally prevent them from popping out and getting dislodged. This may be the reason that they do tend to stay put while running or jogging with them.

3. Software and features of OnePlus Buds Z

The OnePlus Buds Z work with two different apps on Android, one for OnePlus phones and a different one for the rest.

For the OnePlus phone, you get a built-in app called OnePlus Buds. This app doesn’t really show up unless you have the OnePlus Buds or OnePlus Buds Z connected to your phone. Here, the app will show you the battery life of the earbuds, change the touch gestures, change the codec (AAC or SBC), toggle the Bluetooth profiles, and update the firmware. There is also a Find device feature that lets you see their last known location using Google’s Find My Device app and also make them ring in case you misplaced them somewhere close to you.

You can only double-tap the side panel on either earbud to activate one of the four preset functions. You can play/pause, activate the voice assistant, go to the previous track, or go to the next track. You can also press and hold for three seconds to switch between the currently paired and previously paired devices.

4. Audio Quality of OnePlus Buds Z

OnePlus Buds Z comes with a 10mm driver which is smaller than the 13.4mm one in the original Buds. It has included Bass Boost technology to enhance bass, while the earbuds will also support 3D Audio.

The OnePlus Buds Z has the best audio quality for the lowest price. They have a warm, bassy sound with high-end sparkle thrown in for good measure. The OnePlus Buds Z has a very strong low-end.

5. MicroPhone of OnePlus Buds Z

The microphone performance on the OnePlus Buds Z is adequate. It performed so well in recorded audio tests and during actual voice calls when tested. The headset has no issue relaying the voice to the other party. For basic voice and video calls, the microphone performance here is amazing.

6. Connectivity of OnePlus Buds Z

The OnePlus Buds Z had reliable connectivity during testing. Buds Z  supports wireless transmission via Bluetooth 5.0 connection. The wireless range of the earbuds is 10m. The earphone also supports Quick Pair that lets the earphone connect automatically with the last paired device when taken out of the case. The dedicated gaming mode helps bring down the latency as low as 103ms. Similarly, the earphones can automatically pause the music when they are taken out of the ear.

7. Battery of OnePlus Buds Z

The OnePlus Buds Z has a claimed battery life of 5 hours of continuous use and 20 hours combined when you add the three additional charges it provides i.e, 450mah Battery.

OnePlus also claims 3 hours of battery life after a 10-minute charge when both the earphones and the case are charging.

OnePlus Buds Z has been available on OnePlus official retail stores for sale in Nepal at the price of Rs.6790.


The OnePlus Buds Z is very well-designed and build at a great price. As we mentioned earlier, they have an IP55 rating for dust and water resistance, which makes them safe for use during light rain or sweaty workouts which surely attracts many people’s minds.
