Description

The OPPO Enco Free are true wireless in-ear earbuds designed to deliver a seamless listening experience for everyday life. They feature a sleek design and a range of smart functions that make listening to music and making calls more comfortable.

Sound Quality and Technology

Equipped with a 13.4 mm dynamic driver, the Enco Free delivers impressive audio performance. The unique design of the driver, featuring an FPC positioning system and a composite diaphragm, ensures a detailed, clear, and dynamic sound. The earbuds use OPPO’s industry-leading Binaural Simultaneous Bluetooth® Transmission technology to send sound to both ears at the same time, which provides a stable and highly synchronized audio connection, especially for gaming and videos.

Smart Features

The Enco Free earbuds feature intuitive control through swipe and tap gestures directly on the stem of the earbuds. A double-tap allows you to answer calls or start/pause music. Swiping on the left earbud can adjust the volume, while swiping on the right earbud allows you to switch tracks. The wearing detection feature automatically pauses music playback as soon as an earbud is removed and resumes it when it is put back in.

Calls and Battery Life

For clear phone calls in any environment, the Enco Free uses an advanced Dual-Microphone Beamforming technology and an AI Uplink Noise Cancellation. These technologies effectively filter out background noise so that your voice is transmitted clearly and distinctly. With the charging case, the earbuds offer a total runtime of up to 25 hours of music playback or 15 hours of talk time. A single charge allows for up to 5 hours of music listening.
