Battery life is the quiet hero of wireless headphones. A pair can sound wonderful, but if the charge dies before the workday ends, none of it matters. Sony has built its reputation on squeezing every possible minute from its batteries, and the WH-CH520 is a focused demonstration of that strength: a lightweight on-ear headphone that Sony rates at up to 50 hours of playback, with quick charging and multipoint connection to make the long battery practical. I wore the black WH-CH520 through workdays, commutes, and evening calls for several weeks, and this review covers how long the battery truly lasts, how they sound, and how they handle real life.

The WH-CH520 sits in the sweet spot of Sony's range: affordable enough for everyday buyers, well built enough for daily use, and equipped with the battery and connectivity features that make wireless listening effortless. This review walks through the design, the sound, the battery, and the honest limits of an on-ear headphone at this price.
Design and Build
The WH-CH520 is refreshingly light. The on-ear design with a padded headband and soft ear cushions weighs so little that it disappears during long listening sessions, and the swivel ear cups rotate flat, which makes the headphones easy to store and pack. The black finish is understated and professional, and the controls, including volume, playback, and call buttons, sit on the ear cups where they are easy to reach without looking.
The build is solid for the price class. The frame flexes confidently rather than creaking, the cushions are comfortable against the ears, and the folding mechanism feels durable. There is no heavy metal construction here, but there does not need to be, because the lightness is a feature, not a compromise. A USB-C port handles charging, and the cable is short and simple. The whole package is designed for people who want a dependable daily headphone, not a showpiece.
Key Features
The headline feature is the battery. Sony rates the WH-CH520 at up to 50 hours of playback on a single charge, which is extraordinary for a headphone in this class, and quick charging tops the battery back up fast enough that a short charge delivers hours of listening. For a commuter, a traveler, or anyone who forgets to charge, that battery is the difference between a reliable daily tool and another dead gadget.
Multipoint connection is the second feature that changes daily use. The headphones can pair with two devices simultaneously and switch between them automatically, so you can be watching a video on your laptop and take a call on your phone without reconnecting anything. It is the kind of feature that sounds minor on a spec sheet and becomes essential in practice, and Sony implements it cleanly.
Call quality rounds out the package. The built-in microphone is tuned for voice, with processing that reduces echo and background noise, so calls stay clear in normal environments. The headphones also support Sony's companion app, which offers an equalizer for tailoring the sound, and the quick charge and voice assistant support make them a complete daily companion.
Real-World Performance
I charged the WH-CH520 once and then used them across a full week of workdays without reaching for the cable. Across roughly four hours of daily use with music, calls, and the occasional video, the battery meter barely moved, and the stated 50 hour figure felt honest rather than optimistic. When I finally did plug them in, the quick charge added enough power for several more hours in a short stop, which is the battery behavior everyone hopes for and few headphones deliver.
Sound quality exceeded my expectations for the price. The headphones produce a lively, energetic sound with clear highs and a satisfying low end, and the default tuning suits pop, rock, and podcasts alike. Vocals come through cleanly, and the app's equalizer lets you tilt the sound toward your taste if the stock tuning is not perfect. The on-ear seal is not isolating like a noise canceling headphone, so ambient noise bleeds in, but the sound quality itself punches well above the price point.
Multipoint worked exactly as advertised. I kept the headphones connected to a phone and a laptop, and switching between the two was seamless: a call on the phone paused the laptop video, and hanging up returned to the video without any manual reconnection. Calls themselves were clear on both ends, with the mic handling office background noise well enough that callers never complained. The lightweight design meant I forgot I was wearing them, which is the highest compliment an on-ear headphone can earn.
The honest limits are about the format, not the quality. As an on-ear headphone, the WH-CH520 does not offer the immersive seal or noise canceling of Sony's over-ear flagships, so in loud environments like planes and busy offices you will hear the world around you. There is also no carry case included, and the top volume range can get slightly harsh on some tracks, though most listeners will not push it that far. None of these are faults for the price; they are simply the boundaries of an on-ear design.
One detail worth noting is how the companion app changes the experience. The Sony app adds an equalizer that adjusts the sound signature, and a simple toggle between presets made the headphones feel like a different product for bass-heavy music versus spoken content. Voice assistant access also works from the ear cup, which proved handy for checking the weather or setting a timer without touching a phone. The extra software support is the kind of polish that separates this headphone from the anonymous budget pairs in the same aisle.

- Lightweight and comfortable for long wear
- Multipoint connection for two devices at once
- Clear call quality with echo reduction

How It Compares
The WH-CH520 competes in the crowded budget wireless headphone market, and the table below compares it against a typical over-ear wireless headphone at a similar price.
| Feature | Sony WH-CH520 | Over-Ear Budget Pair |
|---|---|---|
| Type | On-ear | Over-ear |
| Battery life | Up to 50 hours | 30 hours typical |
| Multipoint | Yes | Often no |
| Weight | Very light | Heavier |
| Noise isolation | Limited | Better seal |
An over-ear rival may offer a better seal and slightly fuller bass, but it usually costs more, weighs more, and carries a shorter battery. The WH-CH520 wins on battery, weight, and multipoint, which are the features that matter most for daily commuters and office workers. If you want the lightest reliable wireless companion, the CH520 is the smarter pick.
Who Should Buy It
Buy the Sony WH-CH520 if you want a lightweight wireless headphone for daily use that will not die on you, if you switch between a phone and a laptop all day, or if you take a lot of calls. It suits commuters, office workers, students, and anyone who values battery life and comfort above heavy bass and noise canceling.
Skip it if you need true noise canceling for loud travel or an open office, or if you want the fuller sound and stronger seal of an over-ear design. For a dependable, comfortable daily headphone at a sensible price, the WH-CH520 is an excellent choice. You can check the current price of the Sony WH-CH520 on Amazon when you are ready to order.
How We Test
I tested the Sony WH-CH520 over several weeks of daily use, including full workdays of music and calls, commutes, and evening listening. I tracked real battery life against Sony's rating, tested quick charging with timed charges, used multipoint across a phone and laptop for calls and video, and evaluated sound quality across music genres, podcasts, and calls in normal office conditions.
I did not measure battery life in a lab, and call quality can vary with your phone and environment.
