Whether you're a casual listener or a serious audiophile, having a high-quality pair of headphones can greatly enhance your listening experience. Here, we'll take a closer look at two newest models from Sony's wireless headphone line-up - the WHCH520 and WHCH720 - and explore their features and performance.


The Sony WHCH520 and WHCH720 headphones are both designed for comfort and style. They feature a sleek and modern over-ear design with adjustable headbands and cushioned ear cups that provide a comfortable fit for extended listening sessions. The WHCH520 is available in black, white, beige and blue colour options, while the WHCH720 comes in black, blue and white, giving you choices to match your personal style.


Both models are built with durable materials and feel well-constructed, ensuring longevity and reliability. They are also foldable, making them convenient for storage and travel. The ear cups can swivel flat, allowing you to easily pack them in your bag or carry-on without taking up too much space.


One of the standout features of the WHCH520 and WHCH720 headphones is their wireless connectivity, offering you the freedom to move without being tethered to your device. Both models utilize Multi-Point Bluetooth technology, allowing you to easily connect them to your smartphone, tablet, or other Bluetooth-enabled devices at the same time.


The WHCH520 and WHCH720 headphones also support NFC (Near Field Communication) pairing, which allows you to quickly connect them to your device by simply tapping them together. This feature is especially handy if you have an NFC-enabled device and want a seamless and hassle-free pairing experience.


In terms of battery life, the WHCH520 and WHCH720 offer impressive performance. The WHCH720 boasts up to 35 hours of continuous music playback on a single charge, while the WHCH520 offers even longer battery life with up to 50 hours of playtime. This means you can enjoy your favourite tunes without worrying about running out of power during your daily commutes or long trips.


When it comes to sound quality, Sony is known for its exceptional audio performance, and the WHCH520 and WHCH720 headphones are no exception. Both models feature powerful 30mm drivers that deliver clear and dynamic sound with well-defined bass, crisp midrange, and detailed treble.


The WHCH720 headphones, in particular, come with an additional feature called Digital Sound Enhancement Engine (DSEE) that enhances the quality of compressed music files, providing a richer and more immersive listening experience. This feature is great for those who listen to music on streaming platforms or have a large collection of compressed audio files.


Another noteworthy feature of the WHCH520 and WHCH720 is their built-in microphone, allowing you to make hands-free calls and easily access voice assistants like Google Assistant or Siri. The call quality is clear and the microphone picks up your voice accurately, ensuring smooth communication even in noisy environments.



The WHCH520 and WHCH720 headphones are designed with convenience in mind. Both models come with on-ear controls that allow you to easily adjust the volume, skip tracks, and pause/play your music without having to reach for your device. The controls are intuitive and responsive, ensuring a smooth and hassle-free user experience.


Additionally, the WHCH520 and WHCH720 feature a quick charging function that gives you hours of playback with just a few minutes of charging. This is especially handy when you're in a hurry and need.
