Mid-range true wireless earbuds created by OPPO in collaboration with legendary Danish hi-fi company Dynaudio. At the heart of the OPPO Enco Free2 headphones is a pair of dynamic drivers. The sensitivity of the model is 103 dB, and the frequency claimed by the manufacturer is from 20 Hz to 20 kHz. The ears are equipped with three built-in microphones with active noise reduction, which provides a noise reduction depth of up to 42 dB for the highest quality sound even in strong winds or on a crowded noisy street. There is also a special transparent mode and support for the AAC codec, and OPPO 3's custom sound amplification technology compensates the sound according to the sensitivity of the user's ear (this requires installing a proprietary application on a compatible smartphone). Co...nnections to the signal source are made via the Bluetooth v 5.2 wireless protocol, which provides a reliable and accurate connection within a radius of up to 10 m. The “native” battery life of the headphones is 4 hours (with activated noise reduction mode) and 7 hours (without noise reduction mode), but thanks to the complete case, this time can be increased by 14 hours.
