OnePlus Buds 4 Full Review

1. Premium Sound Quality with Dual Drivers

The OnePlus Buds 4 is built for listeners who want a detailed and engaging audio experience. Its dual-driver configuration combines an 11 mm woofer for low-frequency response with a 6 mm tweeter for high-frequency detail.

This design helps produce punchy bass, clear vocals, and crisp treble across different types of music. Whether you enjoy pop, rock, electronic music, podcasts, instrumental tracks, or movies, the dual-driver system is designed to provide a rich and balanced listening experience.

The dual DAC architecture provides separate digital-to-analogue conversion for the two drivers, supporting more precise audio tuning.

2. Adaptive Active Noise Cancellation

One of the standout features of the OnePlus Buds 4 is its real-time adaptive active noise cancellation. The system can reduce noise by up to 55 dB within a tested frequency range of up to 5,500 Hz.

ANC is useful when commuting, studying, working in a busy office, or listening in other noisy environments. The earbuds also offer an Adaptive Mode that helps balance noise cancellation with awareness of your surroundings.

Transparency Mode allows external sounds to pass through so that you can remain more aware of nearby conversations and environmental sounds without removing the earbuds.

Actual noise cancellation performance varies depending on fit, ear-tip selection, surrounding noise, and other conditions.

3. High-Resolution Wireless Audio Support

The OnePlus Buds 4 supports the LHDC 5.0 audio codec, which can deliver high-resolution wireless audio at up to 24-bit/192 kHz on compatible devices.

This feature is particularly useful for listeners who value audio detail and use compatible Android smartphones and supported audio sources. AAC and SBC are also supported for broader Bluetooth compatibility.

Hi-Res LHDC functionality is not supported on iOS devices, and availability depends on the smartphone, software, application, and audio source.

4. Clearer Calls with AI Noise Cancellation

The OnePlus Buds 4 includes three microphones in each earbud and AI-assisted call noise cancellation. The microphone system is designed to help reduce distracting background sounds and make your voice clearer during calls.

These features can be useful for online classes, remote work, business calls, voice chats, and everyday conversations.

Call quality may vary depending on wind, environmental noise, network conditions, and the device or application being used.

5. Long-Lasting Battery Performance

Battery endurance is another important advantage of the OnePlus Buds 4. The earbuds can provide up to 11 hours of music playback on a single charge with ANC turned off, or up to 6 hours with ANC turned on, using AAC under specified laboratory conditions.

With the charging case, total playback can reach up to 45 hours with ANC off and up to 24 hours with ANC on.

For compatible playback conditions, a 10-minute charge using the earbuds and charging case can deliver up to 11 hours of playback. Actual battery performance depends on volume, codec, ANC settings, calls, and other usage factors.

6. Bluetooth 5.4 and Dual-Device Connectivity

Bluetooth 5.4 supports wireless audio connections with compatible devices. Dual-device connectivity lets you connect the earbuds to two supported devices, such as a laptop and a smartphone, for more convenient everyday use.

Google Fast Pair makes pairing easier with supported Android devices. The OnePlus Buds 4 also supports low-latency performance of up to 47 ms under specified conditions, which can help reduce the delay between on-screen action and audio during compatible gaming sessions.

Some connectivity features depend on the smartphone model, operating system, and software version.

7. Personalized Audio and Convenient Controls

The OnePlus Buds 4 offers several audio customization options to suit different listening preferences.

• OnePlus 3D Audio: Creates a more immersive spatial listening experience.
• Golden Sound: Personalizes audio based on a listening assessment.
• Sound Master EQ: Includes preset sound profiles and a customizable six-band equalizer.
• BassWave: Helps enhance low-frequency performance.
• Volume Swipe Control: Allows convenient volume adjustment using the earbud stems.
• Touch Controls: Supports playback and track control, along with switching between noise cancellation and transparency modes.

Supported settings and controls may require a compatible OnePlus smartphone or the HeyMelody application.

8. Comfortable Design and IP55 Resistance

The OnePlus Buds 4 features a compact true wireless design intended for everyday listening. Its lightweight earbuds are suitable for commuting, studying, office use, and casual workouts when fitted securely.

The IP55 rating applies to the earbuds, providing resistance to dust and water under specified test conditions. The charging case is not IP55-rated, so it should be kept away from water and excessive moisture.

Water resistance can diminish with wear and does not mean the product is waterproof.
