OPPO Enco W31 True Wireless Earphones - White

Fast, Stable, Smooth Connection: Instead of having a primary and secondary headphone, audio can be transmitted to both ears at a time, which ensures a fast and smooth transmission. Meanwhile, system-wide optimizations intended to eliminate delay, lag, incompatibility and other disturbances help boost your signal quality for an undisrupted listening experience.

Immerse Yourself in Your Music Bass Mode: Enhanced bass for a powerful sound that brings out bass-heavy rhythms. Balance Mode: Balanced sound across high, middle, and low frequencies. Be Heard as Clearly as in Person Dual-Microphone Noise Cancellation during Calls Noisy surroundings can no longer compete with your voice during calls, thanks to dual-microphone beamforming, an environmental noise cancellation algorithm, and an anti-wind noise chamber.

Wearing Detection: Automatic Play & Pause To quick-pair the headphones with your smartphone 2, just tap the button that pops up on your screen. Every time you open the charging case, the connection will be automatically resumed right away. Infrared optical sensors detect whether you're wearing the headphones and pause or play your audio in response, so you don't need to take out your phone each time.

Intelligent Touch Controls Change audio mode (balance mode/bass mode): double tap on left side Next song: double tap on right side Activate voice assistant: triple tap on either side
