OnePlus Buds Pro 4 Officially Revealed: Dual Drivers with Dynaudio Tuning, 2x Stronger ANC, 53-Hour Battery Life, and AI Live Translation

Following the successful rollout of the Buds Pro 3, OnePlus is moving swiftly to update the summit of its audio portfolio. The company has officially published the product architecture for the OnePlus Buds Pro 4, revealing significant hardware redesigns across acoustic drivers, digital signal processing, and battery longevity.

Partnering once again with Danish luxury audio firm Dynaudio, the OnePlus Buds Pro 4 introduce an upgraded acoustic engine powered by dual dynamic drivers with dual independent digital-to-analog converters (DACs).

Beyond core acoustics, the earbuds deliver a claimed 2x improvement in active noise cancellation (ANC), bone-conduction voice isolation, a 53-hour maximum battery runtime, and native integration with Google Gemini and ColorOS 17 AI translation.

While official Indian pricing remains under wraps ahead of local rollout events, the earbuds are expected to land in the ₹12,999 to ₹13,999 bracket, directly targeting the high-end TWS market.

Acoustic Architecture: Dynaudio Co-Tuning & Dual DACs

The acoustic foundation of the Buds Pro 4 undergoes a ground-up redesign:

• Dual-Driver Array: The system pairs an 11mm composite woofer for extended sub-bass impact with a 6mm planar magnetic tweeter engineered for crisp high frequencies up to 40,000 Hz.
• Dual Independent DACs: Rather than routing all frequencies through a single converter, each driver is fed by its own dedicated digital-to-analog converter. OnePlus notes this independent architecture delivers up to a 50% increase in clean bass power without bleeding into the mid-range.
• Hi-Res Audio with LHDC 5.0: Supports transmission bitrates up to 1Mbps at 24-bit/192kHz via the low-latency LHDC 5.0 codec, preserving studio-grade dynamic range on supported smartphones.
• Personalized “Golden Sound”: Users can take an on-ear hearing canal test that generates a customized EQ profile to compensate for individual hearing sensitivities across different frequencies.

Noise Cancellation & Voice Pickup

• 2x Stronger Ambient Suppression: Moving away from static decibel metrics, OnePlus claims the new adaptive real-time ANC array is twice as effective at eliminating ambient distractions-such as jet engines, café chatter, and low-frequency rail hum-by constantly analyzing environmental acoustics.
• Triple-Mic + Bone Conduction VPU: Voice calls are handled by three beamforming microphones assisted by an integrated bone-conduction Voice Pick-Up (VPU) sensor. The sensor detects physical vibrations through the jawbone, isolating spoken vocals even in 25 km/h wind conditions.
• Dolby Clear Audio Recording: Built-in processing utilizes Dolby algorithms to capture broadcast-clean vocal audio tracks when recording video on paired smartphones.

Intelligence, Ergonomics & Posture Tracking

• ColorOS 17 AI Live Translation: When paired with OnePlus or OPPO devices running ColorOS 17, the earbuds facilitate real-time, two-way language translation directly into the user’s ears.
• Google Gemini Direct Access: Voice prompts can trigger Google’s Gemini assistant hands-free, enabling on-the-go summaries, navigation queries, and schedule management.
• Neck Health Posture Alerts: Built-in inertial measurement unit (IMU) sensors track head angles, sending subtle audio alerts when the user maintains a hunched or tilted neck posture for prolonged periods.
• 39ms Ultra-Low Latency: When Game Mode is engaged on compatible devices, latency drops to an esports-ready 39 milliseconds.

Battery Longevity & Charging Speeds

Endurance receives one of the most substantial upgrades in the product’s history:

• 53-Hour Total Endurance: With ANC disabled, the earbuds deliver up to 13 hours of continuous playback on a single charge, expanding to 53 hours total with the pebble-style charging case.
• 26 Hours with ANC: Enabling active noise cancellation on standard codecs still delivers a solid 26 hours of total listening time.
• Fast & Wireless Power: A brief 10-minute wired charge yields up to 14 hours of playback, backed by native Qi wireless charging coil integration on the base of the case.
• Ingress Protection: The individual earpieces hold an IP55 rating for sweat and dust resistance during workouts.
