OnePlus held a spring product launch on Tuesday, and announced the latest wireless headset Bullets Wireless Z at the same time as the flagship new mobile phone.
OnePlus said that when fully charged, users can get 20 hours of continuous use at a time.
The new charging technology allows Bullets Wireless Z to charge for 10 hours of use in just 10 minutes.
In contrast, Bullets Wireless 2 headphones can only promise 14 hours of use when fully charged.
In addition, the waterproof rating of Bullets Wireless Z wireless headphones reaches IP55, but this is only to the extent that they may not be damaged when worn on rainy days.
Another big change is the price. The Bullets Wireless Z sells for $49.95, about half of the previous generation.
Bullets Wireless Z is available in black, blue, mint and oatmeal colors, and will be sold together with the OnePlus 8 series.
