Radically redesigned cutting-edge audio.
Speakers are the heart and soul of your headphones. OPPO Enco Free pack in cutting-edge ultra-dynamic speakers* to deliver incredible audio performance, combining the FPC positioning system used in high-end stereo equipment with a sophisticated dual magnetic circuit and composite diaphragm made of titanium dome and magnalium cladding. Powered by six patented technologies* that enhance the detail, bass, and dynamic range of your music, you get a studio-quality listening experience you can enjoy anywhere.
Fast, stable audio delivered straight to your ears.
OPPO’s industry-leading binaural simultaneous Bluetooth transmission* delivers sound to the left and right ears simultaneously, giving you highly synchronized audio. Meanwhile, system-wide optimizations intended to eliminate delay, lag, incompatibility and other disturbances help boost your signal quality for an undisrupted experience, whether it is gaming, watching videos, or making calls.
Be heard, wherever you are.
In the mobile era, there’s no time for worrying when or where you’ll be able to take a call. OPPO’s advanced dual microphone beam-forming technology and AI uplink noise cancellation work together to shield your calls from outside noise, so your voice can be heard clearly in any environment.
Intuitive controls, right at your fingertips.
Double-tap on either side of your OPPO Enco Free headphones is all it takes to answer calls or switch your music on and off. To adjust the volume or change tracks, just slide your finger up or down on the headphones*.
