Huawei's FreeLace and FreeLace Pro earpieces can be charged on the go.
The earpieces have an in-built USB-C connector, and can be charged with phones or tablets.
To charge the earpieces with a phone, the phone will need to have a USB-C port as well as reverse charging capabilities, however.
5-minute fast charging
Certain Huawei phones also support fast charging for the FreeLace Pro earpieces.
A 5-minute quick charge can add up to five hours of play time, Huawei said.
The earpieces will also automatically connect to the phones using Huawei HiPair, which means that they will not need to be paired using bluetooth.
Note that the phones must be running EMUI 9.1 or later versions of the Huawei operating system to support this function.
When tested out with a Huawei P30 Pro phone on EMUI 10.1, the charging took slightly longer in reality, however, perhaps due to other apps running on the phone:
New colour launched for FreeLace Pro series
With a full charge, the FreeLace Pro series earpieces can last for 24 hours without noise-cancellation and 16 hours with the noise-cancellation function activated.
The series also have earpieces in three other colours: green, black and white.
