Oppow3 1 smart headset

OPPO Enco W3 1 Smart Edition supports passive noise reduction, but does not support active noise reduction. And the uplink noise reduction algorithm of single microphone call can effectively reduce the surrounding noise and bring you a clear call effect.

OPPO Enco W3 1 Smart headphones can be used independently. Before use, you need to put two earphones in the charging box to connect with the mobile phone, and then take out a single earphone for use.

The Enco W3 1 intelligent version does not distinguish between primary and secondary headphones, and adopts the mechanism of simultaneous binaural transmission. Enco W3 1 Smart Edition supports adaptation to all OPPO phones and other brands of mobile phones with Bluetooth function.

This answer applies to all OPPO models.
