Design & Build Quality

OnePlus Bullets Wireless Z comes in 5 colours – Black, Blue, Green, Orange & White, and the Boult ProBass comes in 4 colours options with attractive names – Black, Onyx Grey, Crimson Red & Azure Blue.

Bullets Z earbuds have a cool glossy finish and a super comfortable neckband made of silicone rubber. The control panel also looks great.

Boult ProBass might look a bit bulky, the neckband is solid, a bit heavy. You can really feel the heaviness if you take both in your hands and compare.

The build quality of both earphones is solid. The design of Boult might be a bit old-fashioned but they didn’t compromise to use good quality material.

Even though both are tough and solid but for design, my vote is on OnePlus Bullets Z.

Bass & Sound Quality

OnePlus Bullets Z Edition got the ideal frequency of 20Hz – 20KHz. I’m not really sure about the exact numbers of Boult ProBass due to lack of information but I’m guessing it will be the same.

OnePlus Bullets Z has 9.2 mm drivers which provide good quality bass but are not totally satisfactory for bass lovers. Boult didn’t mention the driver size but personally, the bass of Boulth ProBass is a bit lower compared to Bullets Z.

Both got nice sound quality. You can’t really go wrong in this part. This time OnePlus didn’t mention the impedance but it’s 30 ohms for Boult ProBass.

But based on the sound quality I can say that the OnePlus Bullets Z also has 30-32 ohms impedance.

Even though the sound quality is great for both, OnePlus Bullets Z got an advantage because of the bass.

Battery Life & Charging Time

The Warp charge technology of the OnePlus is really a game-changer. OnePlus promises that just 10 minutes charge can provide 10 hours of playtime and 20 hours of battery life with a full charge.

On the other hand, Boult ProBass Curve has 12-15 hours of playback time. It takes 1-1.5 hours to get fully charged.

Remote & Functions

Both editions have a remote and mic with all the necessary buttons to pause/play songs, control the volume, and power on/off.

OnePlus Bullets Z got a separate remote for the buttons while Boulth ProBass Curve added all the buttons with the end of the neckband.


Bluetooth Version: Both editions have Bluetooth 5.0 with a 10 m range.

Water-Resistance: Bullets Z and ProBass Curve have IP55 and IPX5 water-resistant ratings respectively. IP55 can resist dust, sweat, and mild spays while IPX5 has all the features except dust resistance.

Accessories: USB-C cable for charging, earbuds of different sizes, and all the required papers like the manual, warranty card, etc are included.
