OPPO Enco W11 True Wireless Earphones White - Binaural simultaneous Bluetooth® transmission, Enhanced bass, IP55 Dust and water resistance

OPPO Enco W11 True Wireless Earphones White Kay Features: Binaural simultaneous Bluetooth® transmission Enhanced bass IP55 Dust and water resistance Less latency, more stability Instead of receiving signals on one side and sending them to the other, the W11 headphones receive signals on both sides at the same time. As a result, latency is lower and the connection is more stable. Bluetooth® 5.0 - Audio that’s with you all the way To strengthen the effect, the built-in Bluetooth 5.0 chip boosts resistance to signal interference, letting you enjoy uninterrupted audio. Pairing that always remembers Once you've paired the W11 headphones with your device, they'll automatically resume connection whenever you use them within 10 metres of it. Whether your phone is in your pocket or across the room, your music is right with you. Listen on, and on, and on On a single charge, enjoy up to 5 hours of playback time without the charging case, or 20 hours with it. Just a 15 minutes charge can power 1 hour of playback time, so your music can accompany you even when time is too tight for a full charge.
