The Sony WH-CH520 Wireless Headphones in Blue combine lightweight comfort, long battery life, and reliable Bluetooth performance in a stylish everyday design. Built for commuting, studying, office use, and casual listening, the WH-CH520 offers Sony’s signature balanced sound tuning at an affordable price point.
The headphones feature a lightweight on-ear design weighing only around 147 grams, making them comfortable for extended listening sessions. The soft ear cushions and adjustable headband help create a secure fit while maintaining portability for travel and daily use. The matte blue finish adds a modern look that stands out without being overly bright.
Sony equipped the WH-CH520 with 30 mm drivers that deliver clear vocals, balanced mids, and decent bass response for music, streaming, podcasts, and calls. The headphones support Sony’s Digital Sound Enhancement Engine (DSEE), which helps restore compressed digital audio for a richer listening experience when streaming music.
Battery performance is one of the strongest features of the WH-CH520. Sony rates the headphones for up to 40–50 hours of playback depending on usage settings, making them ideal for users who prefer charging less frequently. Quick charging support through USB-C provides around 1.5 hours of playback from just a short charging session.
Bluetooth 5.2 connectivity allows stable wireless pairing with smartphones, tablets, laptops, and gaming handhelds. The headphones also support multipoint connection, enabling simultaneous pairing with two devices for easier switching between calls and media playback. Built-in microphones support hands-free calls and voice assistant access with Google Assistant and Siri compatibility.
Community feedback frequently praises the excellent battery life, lightweight comfort, and dependable everyday performance. Some users note that the on-ear design provides less passive noise isolation compared to over-ear headphones and may feel tighter during very long listening sessions. A few Reddit users also mentioned that people with longer hair should be careful around the hinge area where hair can occasionally get caught.
