Oppo claims that the Oppo Enco Free is the first-ever true wireless earbud with a 13.4mm dynamic driver. Furthermore, the driver is said to have a sensitivity of 120dB.
In terms of the batteries, the Oppo Enco Free has a 31mAh battery that offers about five hours of music playback. That too on a single charge. Additionally, it can offer 20 hours more along with the 410mAh charging case. Also, it can be controlled using a slide and double-tap of the left earbud.
Moreover, the earbud has optimized AI that helps to cancel noise during calls. Another interesting thing about the device is that it has automatic wear detection. That means as soon as the user takes the buds out of their ear, the music will automatically stop and resume as soon as they put it back.
