OnePlus Buds 4 Overview

Design and Build

The upcoming OnePlus Buds 4 feature a sleek and compact in-ear design with a premium matte metallic finish that gives the earbuds a modern and refined look. Each earbud weighs only 4.3 grams, making them lightweight and comfortable for long listening sessions without causing ear fatigue. While the official IP rating has not yet been confirmed, the Buds 4 are expected to include basic resistance against dust and water for everyday durability.

The earbuds are available in two elegant color options:

• Pine Green
• Space Gray

Audio Performance and Active Noise Cancellation

The OnePlus Buds 4 are equipped with a flagship-grade coaxial dual-driver system paired with dual DACs, delivering rich bass, crisp vocals, and detailed treble across a wide frequency range. This advanced setup enhances overall sound clarity and preserves finer audio details for a more immersive listening experience.

OnePlus also introduces the “Golden Sound” profile, an intelligent audio tuning feature that adapts the sound signature according to the user’s ear profile for a more personalized listening experience.

A major highlight of the Buds 4 is the powerful 55 dB Hybrid Active Noise Cancellation (ANC) system with ultra-wideband coverage up to 5.5 kHz. This enables the earbuds to effectively minimize surrounding noise, making them ideal for commuting, travel, work, and gaming.

Additionally, the earbuds feature a triple-microphone system with AI-powered call noise reduction, ensuring clearer voice calls even in noisy environments.

AI Features and Battery

The OnePlus Buds 4 also integrate several AI-powered smart features designed to improve convenience and communication.

• Real-Time Voice Translation — Instantly translates conversations in foreign languages, useful for travel and communication.

Battery details have not been fully revealed yet, but the earbuds are expected to deliver approximately 7 hours of continuous music playback on a single charge. Fast charging support is also included, where just one hour of charging can provide around 5 hours of playback time.
