OnePlus Buds 4: Dual Drivers, Dual DACs, and Dominating Adaptive Noise Cancellation

The launch of the OnePlus Buds 4 has fundamentally reshaped the competitive landscape for mid-range true wireless stereo (TWS) earbuds. By integrating an array of audio technologies typically reserved for high-end flagship models, the Buds 4 deliver a compelling value proposition centered on superior sound quality, personalized audio tuning, and class-leading noise cancellation. This is the new standard for anyone seeking a premium listening experience without the flagship price tag.

1. Sound Engineering: Dual Drivers and Twin DACs

The Buds 4 stand out immediately with their advanced acoustic architecture, moving beyond conventional single-driver designs:

• Coaxial Dual-Driver System: Each earbud houses a precisely tuned combination: an 11mm Woofer with a 30-layer ceramic-metal diaphragm dedicated to producing deep, resonant bass and rich low-to-mid frequencies, and a 6mm Tweeter (flat diaphragm) for clear, sparkling highs and pristine treble extension. This physical separation of frequencies creates a wider soundstage and more accurate sound reproduction.
• Twin Tailored DACs (Digital-to-Analog Converters): A key differentiator, the inclusion of dedicated DACs for each driver unit allows for meticulous individual control over the high and low frequencies. This hardware precision results in a more balanced, true-to-life, and detailed sonic output across the entire 15Hz–40kHz frequency response.
• Hi-Res Audio with LHDC 5.0: Supporting the LHDC 5.0 high-resolution codec (up to 1 Mbps, 24 bit/192 kHz), the Buds 4 deliver near-lossless audio quality, ensuring a silky-smooth and detail-filled listening experience that satisfies even discerning audiophiles.

2. Active Noise Cancellation: Flagship-Level Silence

OnePlus has made the Buds 4 a formidable contender in noise isolation, claiming some of the best performance in their class:

• Up to 55dB Real-time Adaptive ANC: The Buds 4 boast a powerful noise reduction depth of up to 55dB across a wide frequency band (up to 5,500Hz). The system uses multiple microphones and an integrated chip to monitor and counteract ambient noise 800 times per second.
• All-New Adaptive Mode: This sophisticated mode continuously tailors the ANC level and frequency curve to your specific ear canal and the external noise environment. Whether you are on a bus, in a cafe, or walking on a windy street, the ANC dynamically adjusts for the most optimal balance between noise isolation and comfort.
• Crystal-Clear Calls: A 3-mic AI Call Noise Cancellation system uses advanced algorithms to isolate the user’s voice while suppressing surrounding sounds, leading to a reported 200% improvement in voice clarity compared to the previous generation.

3. Personalized Audio and Immersive Features

The earbuds offer smart features that allow users to customize and elevate their audio experience:

• OnePlus 3D Audio: Welcome to a sound experience that feels truly three-dimensional and directional. OnePlus 3D Audio creates an immersive, surrounding soundscape for media consumption across both Android and iOS devices.
• Golden Sound: This highly personalized feature maps the user’s unique ear canal structure and combines it with a personalized listening test to craft a bespoke audio profile, delivering a sculpted and purer listening experience perfectly tuned to the individual.
• Sound Master EQ: Users can choose from pre-tuned EQ presets (like Balanced, Serenade, and Bass Mode) or dive into a customizable six-band EQ for manual fine-tuning, complemented by BassWave™ technology for impactful bass delivery.

4. Smart Connectivity and Endurance

• Extended Playtime: The Buds 4 deliver substantial battery life, offering up to 11 hours of continuous playback on the buds alone (ANC Off, AAC) and a generous total playtime of up to 45 hours with the charging case.
• Fast Charging Power: A quick 10-minute charge provides up to 11 hours of music playback, ensuring minimal disruption to your routine.
• Bluetooth 5.4 with Steady Connect: Utilizing the latest Bluetooth standard, the earbuds feature Steady Connect technology, ensuring stable and robust connectivity with an extended range, even in crowded or complex wireless environments.
• Gaming and AI: A dedicated 47ms Low Latency Mode synchronizes audio perfectly for competitive gaming. Furthermore, a simple tap activates the AI Translation feature on a paired OnePlus phone, breaking down language barriers in real-time.
• Durability and Convenience: An IP55 rating guarantees resistance against dust and water splashes, making them a reliable choice for active lifestyles. Features like Dual-Device Connection, Google Fast Pair, and volume swipe control on the earbud stems add daily convenience.

The OnePlus Buds 4 successfully consolidates features once scattered across the market’s most premium options—advanced dual drivers, ultra-high ANC, and intelligent personalization—into a cohesive, high-value package, making it the definitive choice for next-generation TWS audio.
