OnePlus Buds Pro 4: Exciting Features, ANC & 53-Hour Battery
OnePlus has revealed the key features and specifications of its upcoming flagship wireless earbuds, the OnePlus Buds Pro 4, ahead of their expected launch. The new model brings a dual-driver audio system co-developed with Dynaudio, adaptive active noise cancellation (ANC), Hi-Res Audio support and several AI-powered features.
The earbuds also introduce Bluetooth 6.1, dual-device connectivity, spatial audio with head tracking and a claimed battery life of up to 53 hours with the charging case. OnePlus says the new ANC system can reduce up to twice as much background noise as the previous-generation Buds Pro 3.
However, there is an important detail for Indian buyers: OnePlus has revealed the specifications on its global website, but has not yet confirmed the India launch date, price or sale date. The product is therefore best described as revealed or listed ahead of launch, rather than officially launched in India.
OnePlus Buds Pro 4 Launch Date and Price in India
OnePlus has published the Buds Pro 4 product information on its global website, revealing the design, audio hardware, connectivity and battery specifications. However, the company has not announced an official retail launch date or price.
The India launch is also unconfirmed. This means buyers should not rely on unofficial price estimates or assumed launch dates until OnePlus makes a formal announcement.
For context, the previous-generation OnePlus Buds Pro 3 launched in India at ₹11,999. This gives some indication of the product family’s premium positioning, but it does not confirm the price of the Buds Pro 4.

Dynaudio-Tuned Dual Drivers Aim to Improve Sound Quality
One of the biggest highlights of the OnePlus Buds Pro 4 is its dual-driver audio setup, developed in collaboration with Danish audio company Dynaudio.
Each earbud combines an 11mm composite woofer and a 6mm planar tweeter. The two drivers handle different parts of the audio spectrum, with the woofer focusing on bass and lower frequencies while the tweeter handles higher-frequency details.
OnePlus has also equipped each earbud with independent dual DACs. According to the company, the updated audio system delivers 50% more bass-driving force than the Buds Pro 3.
The collaboration with Dynaudio is important because the company is known for its work in audio engineering and speaker technology. The aim is to deliver a more balanced listening experience, with deeper bass and clearer high-frequency reproduction.
However, these improvements are based on OnePlus’s specifications and marketing claims. Independent listening tests will be necessary to determine how noticeable the differences are compared with the previous model.
Hi-Res Audio, LHDC 5.0 and Spatial Audio
The Buds Pro 4 support Hi-Res Audio through the LHDC 5.0 audio codec. OnePlus lists support for transmission rates of up to 1Mbps and audio playback at up to 24-bit/192kHz.
The earbuds also support spatial audio with head tracking. This feature is designed to create a more immersive listening experience by adjusting the perceived direction of sound as the listener moves their head.
Another feature is Golden Sound, which creates a personalised audio profile based on the user’s ear characteristics and hearing range.
The available audio codecs include:
- LHDC
- AAC
- SBC
- LC3
It is worth remembering that access to the highest-quality audio depends on the smartphone, operating system, application and supported codec. Having LHDC 5.0 on the earbuds does not mean every smartphone will automatically deliver the same audio quality.
For users with compatible devices and high-quality music sources, these features could make the Buds Pro 4 an interesting option in the premium wireless earbuds category.
Up to 2x Better Active Noise Cancellation
Noise cancellation is another major area where OnePlus is promoting improvements.
The Buds Pro 4 feature adaptive active noise cancellation with real-time scene recognition. The system is designed to identify changes in the surrounding environment and adjust noise cancellation accordingly.
OnePlus claims that the new earbuds can remove up to twice as much background noise as the Buds Pro 3. The company also claims that voice noise reduction is 2.5 times better than the previous generation.
This could be useful in situations such as:
- Travelling on buses and trains
- Working in busy offices
- Sitting in crowded public places
- Listening to music during flights
- Taking calls in noisy environments
The earbuds also include three microphones and a voice pickup unit (VPU) bone-conduction sensor. These work alongside AI-based noise reduction to improve voice pickup during calls.
While the specifications sound promising, the actual performance will depend on the type of background noise, ear-tip fit and environmental conditions. Independent testing will be needed to verify the claimed improvement.
AI Features: Live Translation and Clear Audio Recording
The Buds Pro 4 are not limited to music playback and noise cancellation. OnePlus has also introduced AI-powered features intended to make the earbuds more useful in everyday situations.
AI Live Translation
The AI Live Translation feature is designed to help users communicate with people who speak different languages. It supports in-person translation across languages, making it potentially useful for travel, conversations and meetings.
However, the feature comes with a compatibility requirement. OnePlus says AI Live Translation requires a OnePlus device running ColorOS 17 or later.
This means users should check their smartphone’s software compatibility before purchasing the earbuds specifically for live translation.
Clear Audio Recording
Another feature is Clear Audio Recording, which uses Dolby audio processing to capture sound through both earbuds simultaneously.
It is designed to provide clearer audio recordings and could be useful for capturing conversations or voice notes.
However, this feature is not universally supported across all smartphones. OnePlus lists compatibility with the OnePlus 10 series and newer models.
These device restrictions are important because some of the headline AI features may not be available to buyers using older OnePlus smartphones or devices from other manufacturers.
Google Gemini Access and Neck Health Monitoring
The OnePlus Buds Pro 4 also support Google Gemini voice access, allowing users to interact with Google’s AI assistant through compatible devices.
This could make it easier to access voice assistance without manually opening an app or typing commands.
Another unusual addition is Neck Health monitoring. The earbuds can use head-tilt alerts to remind users to maintain a healthier posture.
The feature is intended to encourage better everyday habits, especially for people who spend long periods looking down at smartphones or working at desks.
However, OnePlus has not provided extensive details about how the monitoring works or how accurately it identifies posture. It should therefore be considered a wellness reminder rather than a medical assessment.
Gaming Mode Offers 39ms Low Latency
For mobile gamers, OnePlus has included a low-latency gaming mode.
The company claims the Buds Pro 4 can reduce audio latency to as low as 39 milliseconds when paired with select OnePlus smartphones.
Lower latency can help synchronise sound with on-screen action, which is particularly useful in competitive games where audio timing matters.
However, the lowest advertised latency is device-dependent. Users should not assume that every Android smartphone or computer will achieve the same result.
Battery Life: Up to 53 Hours With the Charging Case
Battery life is another notable upgrade on paper.
OnePlus claims that the Buds Pro 4 can deliver up to 13 hours of music playback on the earbuds alone, with ANC switched off and AAC enabled. Combined with the charging case, the total claimed playback time increases to 53 hours.
Battery performance changes significantly when noise cancellation and higher-quality audio codecs are enabled.
| Listening condition | Earbuds only | With charging case |
|---|---|---|
| ANC off, AAC | Up to 13 hours | Up to 53 hours |
| ANC on, AAC | Up to 6 hours | Up to 26 hours |
| ANC on, LHDC | Up to 5.5 hours | Up to 22 hours |
| ANC off, LHDC | Up to 10 hours | Up to 42 hours |
The earbuds also support fast charging. OnePlus claims that a 10-minute charge can provide up to 14 hours of playback when charging the earbuds and case together.
The charging case supports USB Type-C and wireless charging. Compatible OnePlus smartphones can also provide reverse wireless charging for the case.
It is important to understand that the 53-hour figure is a best-case manufacturer claim under specific test conditions. Users who regularly use ANC, LHDC and other features should expect shorter battery life.
Bluetooth 6.1 and Dual-Device Connectivity
The Buds Pro 4 support Bluetooth 6.1, Google Fast Pair and Microsoft Swift Pair.
One of the useful features is dual-device connectivity, which allows the earbuds to remain connected to two compatible devices simultaneously.
For example, users can connect the earbuds to a smartphone and laptop, making it easier to switch between music, video calls and other audio activities.
The listed wireless transmission range is up to 10 metres under suitable conditions.
These features make the Buds Pro 4 more convenient for people who regularly switch between multiple devices during work or entertainment.
Design, Colours and Water Resistance
The OnePlus Buds Pro 4 feature a pebble-inspired charging case with a matte finish and metallic ring. The global product listing shows two colour options:
- Titanium Shadow
- Polar White
Each earbud weighs approximately 5.6 grams, while the charging case weighs around 41.8 grams. The combined weight is approximately 53 grams.
The earbuds carry an IP55 dust and water resistance rating. This provides protection against dust and water jets under specified testing conditions, making them more suitable for everyday use and workouts.
However, the charging case does not carry the same water-resistance rating. Users should avoid exposing the case to water or using it in wet conditions.
The IP55 rating also does not mean the earbuds are waterproof or suitable for swimming.

The India price has not been announced, and several AI features have device restrictions. The advertised ANC improvements and battery figures also need independent verification.
If you already own the Buds Pro 3, upgrading immediately may not be necessary. Waiting for real-world comparisons and the official India price will make it easier to decide whether the improvements justify the expense.
Conclusion
The OnePlus Buds Pro 4 bring several upgrades to the company’s premium wireless earbuds range. The Dynaudio-tuned dual-driver system, adaptive ANC, LHDC 5.0, spatial audio with head tracking and up to 53 hours of claimed battery life make them an interesting upcoming product.
The addition of AI Live Translation, Clear Audio Recording, Gemini voice access and Neck Health monitoring also gives the earbuds more functionality beyond conventional music playback.
However, their overall value will depend on the final price, smartphone compatibility and real-world performance.
For Indian buyers, the best decision right now is to wait for OnePlus to confirm the launch date, pricing and availability.
