My Experience Using It

Noise cancellation performance

The biggest appeal of the WF-C700N is its surprisingly high-performance noise canceling, which is rarely seen in this price range. By optimally controlling the microphones on both sides to generate inverse sound waves, it effectively reduces everyday ambient noise such as train and bus sounds or the chatter in cafés. Despite its compact size, it delivers practical and highly satisfying noise reduction.

Another convenient feature is the Ambient Sound mode, which naturally lets in surrounding sounds. The level of external sound can be adjusted in 20 steps, allowing you to fine-tune it depending on the situation—whether you want to hold a conversation or stay aware of your surroundings on the street. It also uses a mesh structure that reduces wind noise, making it more comfortable to use outdoors.

The WF-C700N also supports Adaptive Sound Control when linked with a smartphone. Depending on your activity—such as staying still, walking, running, or riding in a vehicle—as well as your location, it automatically adjusts noise cancellation, ambient sound, and even the equalizer. This means you don’t have to manually change the settings each time, keeping your listening environment always optimized—something you’d normally expect only from higher-end models.

Having such versatile noise cancellation and ambient sound features at this price point offers excellent value for money. It’s an ideal choice for those who want to try noise-canceling earbuds that are both affordable and genuinely effective.

Sound Quality

The WF-C700N delivers a well-balanced sound across highs, mids, and lows, with vocals and instruments standing out as particularly natural and clear. The bass has a solid presence without overwhelming the mix, resulting in a sound that is engaging yet easy to listen to for long periods.

On top of that, Sony’s proprietary DSEE technology restores high frequencies that are often lost in compressed audio formats such as streaming services or MP3s. This allows you to enjoy a wider, more detailed soundstage even with compressed sources—an impressive advantage in this price range.

In addition, the WF-C700N is a 360 Reality Audio certified model. By using the dedicated “Sound Connect” app, you can experience a spatial sound field that is optimized for the unique shape of your ears. The immersive feeling of being at a live concert gives it a clear advantage over other models in the same price range.

In addition, the app lets you fine-tune the equalizer, allowing you to boost the punch of EDM or bring out the delicate nuances of jazz, tailoring the sound to your personal taste. For its price, the WF-C700N delivers an impressively satisfying level of sound quality.

Compact design and high wearing comfort

The earbuds are designed to be lightweight at just 4.6g each. By minimizing protrusion from the ear, they provide both a comfortable fit and a sleek appearance. In addition, the “Ergonomic Surface Design” ensures a natural fit to the shape of the ear, delivering comfort and stability even during long listening sessions.

Weighing only about 31g, the case is both lightweight and compact, making it easy to carry and convenient for use on the go.

Battery and Waterproof Performance Review

The WF-C700N is also equipped with sufficient waterproof performance for everyday use. With an IPX4 water resistance rating, it can withstand sudden rain or sweat during workouts. This makes it a reliable choice for use at the gym or outdoors. However, since it is not fully waterproof, it should not be used underwater or exposed to strong water j

It features IPX4 water resistance, allowing you to use it worry-free on rainy days or during gym workouts. Its versatile design makes it suitable for both everyday use and sports activities.

Bluetooth Functionality and Connectivity Review

The WF-C700N delivers high stability and low latency thanks to its simultaneous left-and-right transmission. Audio stays in sync even during video playback, providing a smooth experience. It also supports multipoint connectivity, allowing two devices to be connected at the same time. This makes switching seamless—for example, you can finish a meeting on your PC and immediately start playing music on your smartphone.

It also supports multi-pairing for up to 8 devices, which is handy if you use multiple gadgets like Android phones, iPhones, or PCs. On Android devices, Google Fast Pair allows you to connect with just one tap, and the “Find My Device” feature makes it easy to locate your earphones if you misplace them.

Hands-free Call Review

The WF-C700N excels not only in music playback but also in call quality. Its noise suppression feature minimizes background noise, ensuring your voice comes through clearly, even in noisy environments. Additionally, the mesh structure in front of the microphone reduces wind noise, making outdoor conversations more natural and easy to understand.
