Wireless earbuds have become much more than simple audio accessories. Today, users expect premium sound quality, long battery life, crystal-clear calls, and effective Active Noise Cancellation (ANC) even in mid-range models. The OnePlus Buds 4 aim to deliver all of these features while remaining competitively priced.Among these features, Active Noise Cancellation is one of the biggest selling points. Whether you're commuting, working in a busy office, studying at a café, or relaxing during a flight, effective ANC can dramatically improve your listening experience. But how well does the OnePlus Buds 4 perform in real-world situations?In this review, we take a closer look at the Active Noise Cancellation on the OnePlus Buds 4 to see whether it lives up to expectations.
First Impressions
The OnePlus Buds 4 immediately feel like premium earbuds. Their lightweight design, comfortable fit, and compact charging case make them easy to carry and wear throughout the day.Setting up the earbuds is quick, especially for OnePlus smartphone users. Pairing happens almost instantly, and the companion app allows users to customize controls, adjust sound settings, and manage noise cancellation modes with ease.From the first listening session, it's clear that OnePlus has focused on creating a refined audio experience.
What Is Active Noise Cancellation?
Active Noise Cancellation uses built-in microphones to detect surrounding sounds and generate opposite sound waves that reduce unwanted background noise before it reaches your ears.Unlike passive noise isolation, which simply blocks sound using the earbud's physical design, ANC actively works to minimize constant environmental noises.This makes it particularly useful during travel, office work, public transport, flights, and other noisy environments.The better the ANC system, the more immersive your listening experience becomes.
Everyday Noise Reduction
The OnePlus Buds 4 perform impressively during everyday use.Background sounds such as air conditioners, ceiling fans, office equipment, and distant conversations become significantly quieter once ANC is activated.This allows music, podcasts, and videos to remain clear without constantly increasing the volume.Whether you're working from home or studying in a public space, the earbuds help create a calmer listening environment that improves concentration.
Performance During Commuting
Public transportation is one of the biggest tests for any ANC system.On buses, trains, and subways, the OnePlus Buds 4 effectively reduce low-frequency sounds like engine noise, road vibrations, and constant background hum. While louder announcements and nearby conversations may still be partially audible, they become far less distracting.This allows users to enjoy music or podcasts comfortably without raising the volume to unhealthy levels.For daily commuters, the improvement in listening comfort is immediately noticeable.
Office and Workplace Performance
Busy offices often include keyboard clicks, printers, conversations, and general background activity.The OnePlus Buds 4 perform well in these environments by minimizing consistent background noise while allowing users to remain focused on their work.Pairing ANC with instrumental music or white noise creates an even more distraction-free workspace.Professionals who spend long hours working in shared offices will likely appreciate this feature.
Air Travel Experience
Airplane cabins produce continuous low-frequency engine noise that ANC technology is specifically designed to reduce.The OnePlus Buds 4 handle these sounds effectively, making long flights significantly more comfortable. Constant engine hum becomes much less noticeable, allowing passengers to enjoy movies, music, or audiobooks with greater clarity.Although premium flagship earbuds may provide slightly stronger noise cancellation, the OnePlus Buds 4 deliver an impressive travel experience considering their price category.Frequent travelers will find the ANC highly beneficial.
Sound Quality with ANC Enabled
Some wireless earbuds experience noticeable sound quality changes when ANC is activated.Fortunately, the OnePlus Buds 4 maintain excellent audio performance regardless of whether noise cancellation is turned on.Music remains balanced with deep bass, detailed vocals, and clear instrument separation. High frequencies stay crisp without becoming harsh, while mids remain natural and well-controlled.The reduced background noise also allows listeners to appreciate finer audio details that might otherwise go unnoticed.Overall, ANC enhances the listening experience rather than compromising it.
Transparency Mode Adds Flexibility
Effective noise cancellation is only half of the story.The OnePlus Buds 4 also include Transparency Mode, allowing outside sounds to pass through naturally when needed.This feature is useful while walking through busy streets, ordering coffee, speaking with coworkers, or listening for travel announcements without removing the earbuds.Switching between ANC and Transparency Mode is fast and intuitive, making the earbuds suitable for a wide range of situations.
Comfort During Long Listening Sessions
Noise cancellation is most useful when earbuds remain comfortable for extended periods.The OnePlus Buds 4 feature a lightweight design that fits securely without creating excessive pressure inside the ears. Even after several hours of continuous listening, the earbuds remain comfortable enough for work, travel, or entertainment.The secure fit also improves passive noise isolation, allowing the ANC system to perform more effectively.Comfort and noise cancellation work together to create a highly enjoyable listening experience.
Battery Life with ANC Enabled
Active Noise Cancellation naturally consumes additional battery power.Even so, the OnePlus Buds 4 continue to offer excellent battery life. Users can comfortably enjoy several hours of continuous playback with ANC activated, while the charging case provides multiple additional charges throughout the day.Fast charging further improves convenience by quickly restoring listening time whenever needed.For most users, battery life remains more than sufficient even with noise cancellation enabled regularly.
How Does It Compare to the Competition?
The OnePlus Buds 4 compete with several popular wireless earbuds, including the Samsung Galaxy Buds FE, Google Pixel Buds 2a, Nothing Ear, and Sony's mid-range earbuds.Compared to similarly priced competitors, the OnePlus Buds 4 deliver highly competitive ANC performance. They effectively reduce everyday environmental noise while maintaining strong sound quality and excellent comfort.While ultra-premium earbuds from Sony, Bose, or Apple may still offer slightly more advanced noise cancellation, the difference is smaller than many users might expect.For their price, the OnePlus Buds 4 provide outstanding value.
Who Should Buy the OnePlus Buds 4?
The OnePlus Buds 4 are ideal for commuters, students, professionals, travelers, and anyone who regularly listens to music in noisy environments.They're particularly well suited for users who own OnePlus smartphones, as deeper ecosystem integration provides faster pairing and additional software features.Even Android users outside the OnePlus ecosystem will appreciate the earbuds' strong ANC performance, comfortable design, and reliable battery life.
