Dual technology for both crystal-clear music and calls
The W51 headphones have achieved a unique breakthrough in noise reduction for both music and calls. By coordinating a total of 6 microphones with a deep noise reduction algorithm, your wireless earphone experience will never be the same.
In-depth noise reduction for an immersive experience
The W51 comes equipped with a new dual-core digital noise reduction chip and more advanced hybrid noise reduction microphones. They are intelligently optimised to detect and reduce everyday noises1, such as from subways and trains. With a noise reduction depth of 35 dB2, you get an undisturbed listening experience.
Triple microphone noise reduction for clear and carefree calls
Each earphone comes equipped with triple microphone noise reduction technology and redesigned air ducts to prevent wind noises. Whether you are at the train station, on the bus, or riding your bike, a single earphone will capture your voice clearly.
Bluetooth 5.0 provides a fast, stable, and smooth experience
The W51 headphones are powered by Bluetooth 5.0 technology for faster and more stable audio transmission when faced with multiple sources of interference. They provide a stable connection at up to 10 metres away for smooth music and calls even when your phone is not nearby
Listen 4 hours every day and only charge once a week
A 15-minute charge keeps the W51 on for 9 hours5, while a full charge lasts a full 24 hours. Say goodbye to low battery anxiety.
*Up to 20 hours listening time with ANC mode on, 24 hours listening time with ANC off
IP54 Rated dust and water resistance
Structurally designed and certified for IP54 dust and water resistance6. So whether it is the gym or an outdoor commute, listen with peace of mind knowing your headphones are safe.

1. Noise reduction functionality has a more significant effect in the low-frequency range, such as in airplanes or trains, but is not as effective for higher frequencies, such as with nearby human voices.
2. The noise reduction depth data was measured in OPPO's controlled environment with ANC mode on.
3. Qi is the wireless charging standard launched by the Wireless Charging Alliance, which aims to solve wireless charging compatibility for different mobile devices. Any chargers that support the Qi standard can charge W51.
4. Binaural low-latency Bluetooth transmission is compatible with both Qualcomm and MTK mobile platforms.
5. Charging and battery life test data were measured in OPPO's controlled environment with a room temperature of 25℃ and a standard OPPO charger. Actual charging and battery life will vary with different usage environments and chargers.
6. Only the earphones are certified for IP54 dust and waterproofing, not the earphone box. It is recommended to avoid using earphones during extreme sports to prevent damage from sweat penetration.
7. Quick pairing is supported by OPPO phones using ColorOS 7.0 and above, excluding the A series, F series, Reno 2Z, Reno2 F, R15, Reno3 4G version, and Reno3 Pro 4G version, Reno4 4G version, and Reno4 Pro 4G version. Some models will support quick pairing when new versions are released.
8. The voice assistant summoning function is supported by OPPO phones using ColorOS 6.0 and above. Summoning other intelligent voice assistants is also supported. Please consult your relevant mobile phone manufacturer or local distributor for specific details.
