If what you want is a light, hard-wearing Bluetooth pair you rarely have to think about charging, the WH-CH520 sits in that slot. About 147g on the head, 30mm drivers, USB-C charging, and Sony states up to 50 hours of battery. There is no active noise cancellation here, and that is the point: it connects quickly, stays comfortable, and does not need a charger every other day.
Key features
50 hours of battery, charged over USB-C
Sony states up to 50 hours of battery life, and a 3-minute quick charge gives about 1.5 hours of listening. The charging port is USB Type-C, so it shares a cable with most phones and tablets.
Multipoint connection
Pair with two Bluetooth devices at the same time. If a call comes in on your phone while you are watching something on a laptop, the headphones switch over for you.
DSEE
DSEE restores harmonics and detail lost in compression. Compressed streaming audio is what it is aimed at.
Light on-ear fit
At about 147g with on-ear cups, there is less clamp and less weight over a long session. The headband adjusts on each side and the cups swivel flat, so it takes up little room in a bag. EQ can be customised through the Sony | Sound Connect app, which also shows the battery level and handles firmware updates.

Who it's for
- Students and anyone on video calls all week who wants light headphones that last.
- Households with several devices, keeping a laptop and a phone connected together.
- People who want one USB-C cable for everything.
- Who it's not for: anyone trying to cut aircraft or MTR noise. The WH-CH520 has no active noise cancellation, isolation comes only from the physical fit of the ear pads, and in loud places you will end up turning the volume up.

FAQ

Q: Can I plug in a cable? A: Sony's specification page lists Bluetooth connection with a USB Type-C charging port, and does not list a 3.5 mm wired input. If you need a wired fallback, look at another model.
