The Sony WH-CH520 Blue sits between the safe black and the bolder pastels: a calm blue that adds some colour without shouting. It is a natural fit for school and university, where it stands out from the sea of black headphones in a shared classroom or dorm, yet still looks sensible in a lecture or on a video call. The hardware is the same as every other colour in the range, with about 147 g of weight, up to 50 hours of listening per charge according to Sony and two-device multipoint pairing.

Why blue, and who it suits
Blue works for people who want a little personality but not a statement piece. It goes with jeans, school uniforms, navy and grey, and it looks equally at home on a teenager or an adult. It is also practical: a mid-tone blue hides everyday marks better than white, pink or beige, so it copes well with being thrown in a backpack, lent to a sibling or used every day on the bus. In a house or classroom full of identical black pairs, the Sony WH-CH520 Blue is easy to recognise as yours. A wipe with a soft, slightly damp cloth now and then is all the care it needs.
Built around a student day
A typical study day suits these headphones well. Pair them with a laptop for recorded lectures and with a phone for messages and calls, and multipoint keeps both connected so you do not re-pair between classes. The built-in microphone covers group calls and voice assistants. With up to 50 hours of playback per charge, the Sony WH-CH520 Blue can last through a whole week of commuting and revision, and a 3-minute quick charge gives about 1.5 hours if the battery runs low before the bus. The light 147 g build means you can wear them through a long revision session without the weight of a bigger over-ear model.
Sound tuned in the app
Each earcup carries a 30 mm driver with a 20 Hz to 20 kHz response over Bluetooth. Sony’s standard DSEE processing restores some of the high-frequency detail that compressed streaming loses, which helps with music on mobile data. In the Sony Sound Connect app you can set the equaliser: lift the bass for music, or bring voices forward for podcasts and lectures. This is a balanced, everyday sound rather than an audiophile one, and it is not meant for studio work, but for study playlists and video it is clear and easy to listen to for hours.
Battery, charging and connection
Sony lists up to 50 hours of music, up to 40 hours of talk and up to 200 hours of standby for the Sony WH-CH520 Blue. A full charge through USB-C takes about 3 hours; only a USB cable is in the box. These figures come from Sony’s tests, so loud volume shortens them. The connection is Bluetooth 5.2 with about 10 metres of range, and the SBC and AAC codecs cover iPhone and Android.
The rest, in brief
The design is closed-back and on-ear, with soft cushions, an adjustable headband and swivelling earcups. Physical buttons on the earcup control playback, volume and calls. Weight is about 147 g. Sony’s specification page does not list a folding hinge, so for a bag you just swivel the earcups inward.
Who This Is Not For
The Sony WH-CH520 Blue is not for someone who needs active noise cancelling in a loud library, on a plane or in an open office; it has none. There is no 3.5 mm jack, so it cannot be used with a cable for an exam lab or when the battery is empty. On-ear cushions may press after several hours, particularly with glasses. It does not support LDAC, and it is not built for competitive gaming that needs very low latency.
