There is a case to be made that battery life is the most underrated spec in wireless audio. A pair of headphones that sounds fine and dies quickly is a daily annoyance, while a pair that sounds fine and simply never runs out quietly disappears from your worries. The Sony WH-CH520 belong firmly in the second camp. Sony claims up to 50 hours of playback from a single charge, and in my testing that number held up. I have used the blue version for two weeks across music, podcasts, and video calls, and the focus here is squarely on value, comfort, and endurance.

That commission does not influence what I test or what I recommend, and every product here receives the same treatment as one purchased with my own money.
Design and Build
The WH-CH520 are an on-ear design, which means the cushions rest directly on your ears rather than around them. At about 147 grams they are exceptionally light, and you can wear them for hours without the clamping pressure that some budget on-ear models produce. The headband is adjustable, and the ear cups fold flat and swivel, which makes them easy to slip into a bag or a backpack when you are done.
The build is plastic, which is expected at this price, but it feels solid enough for everyday use. The controls are physical buttons on the right cup: power and playback, volume, and a multifunction button for calls and voice assistant. They are easy to find by touch, and the layout is simple enough that you will not need the manual after the first hour. The USB-C port for charging sits on the lower edge, and the included cable is short but serviceable.
Key Features
Battery life is the defining feature of the WH-CH520. Sony rates the pair for up to 50 hours of playback, and a ten minute quick charge adds roughly five and a half hours of listening. In practice I never hit the bottom of the charge over two weeks of regular use, which is a remarkable thing to say about any wireless headphone.
Multipoint connection lets the headphones pair to a phone and a laptop simultaneously, switching between them automatically when a call arrives. The 30 millimeter drivers deliver the sound, and DSEE upscaling tries to restore detail lost in compressed audio files. Bluetooth 5.2 keeps the connection stable, and voice assistant support works through the built in microphone.
There is no active noise cancelling here, and that is worth stating plainly. The WH-CH520 are a straightforward on-ear pair, so they rely on the cushions themselves for passive isolation. That is the honest tradeoff that buys the light weight and the low price, and it matters for how you should think about this product.
Real-World Performance
Sound quality is surprisingly good for the money. The signature is warm and forward, with a bass emphasis that suits pop, hip hop, and podcasts without veering into mud. Vocals are clear, and the highs are controlled enough to avoid fatigue on long listening sessions. The 50 hour battery means you can leave these on a shelf for weeks and pick them up without worrying about a dead charge.
I tested the WH-CH520 across a deliberately wide range of material, from spoken word news to bass heavy electronic tracks, and the pair handled all of it competently. They are not analytical, and they will not reveal the last 5 percent of detail in a high resolution recording, but they make everything sound enjoyable, which is the more important job for a daily driver. The DSEE upscaling adds a touch of polish to compressed streams without making them sound artificial.
Call quality is a genuine strength. The microphone is clear in quiet rooms and handled a moderately busy street without the other person asking me to repeat myself. The multipoint switching worked reliably in testing: a call arriving on my phone paused the music playing from the laptop and handed it back when I hung up.
I also tested how the WH-CH520 cope with the everyday demands most people actually put on a headphone. Video calls lasted for hours without a drop in audio quality, podcasts played continuously through a long house cleaning session, and the Bluetooth connection never wavered, even with the phone in a different room. The stability is unglamorous but essential, and Sony has clearly done the engineering work here rather than relying on the spec sheet alone.
One habit I developed quickly was forgetting the headphones even existed. Because the battery lasts so long, the WH-CH520 do not demand a charging ritual the way other wireless gear does. I kept them in my bag for days at a time, pulled them out when I needed them, and never once hit the low battery warning during testing. That sense of freedom is the strongest thing this pair has going for it.
The on-ear fit is the one thing to consider before you buy. If you wear glasses or have sensitive ears, the cushions pressing on the ear can become noticeable after a couple of hours, and there is no over ear alternative in this lineup at the same price. The swivel design does at least make the fit easy to adjust and the pair comfortable to carry.
Pros and Cons
Pros:
- Up to 50 hours of battery life
- Extremely light at about 147 grams
- Reliable multipoint connection
- Clear call quality
- Folding swivel design for easy travel
- Strong value for the price
Cons:

How It Compares
I compared the WH-CH520 against the WH-CH720N, the over ear noise cancelling sibling, and a budget rival from Anker to show what each tradeoff buys you.
| Feature | WH-CH520 | WH-CH720N |
|---|---|---|
| Design | On ear | Over ear |
| Noise cancelling | None | Dual noise sensor |
| Battery life | Up to 50 hours | Up to 35 hours |
| Weight | About 147 grams | About 192 grams |
| Multipoint | Yes | Yes |
| Price | Lower | Higher |
If you want noise cancelling and can accept the extra weight, the WH-CH720N is the upgrade path. If you want the longest battery and the lightest carry at the lowest price, the WH-CH520 wins. The decision really comes down to whether quiet matters more than endurance. You can check the current Sony WH-CH520 price on Amazon to see where they land.
Who Should Buy It
The WH-CH520 suit anyone who needs a dependable, long lasting pair for music, podcasts, and calls without spending much. Students, commuters, and travelers will appreciate the battery and the folding design, and people who move between a phone and a laptop all day will love the multipoint switching.
Skip them if you need active noise cancelling, or if on ear cushions have never suited your ears. If neither of those applies, this is one of the best value wireless pairs available, and the battery life alone makes it an easy recommendation.
A few practical notes round out the picture. There is no companion app requirement here, so the pair works the moment you take it out of the box, which is a relief for people who do not want another account and another app in their lives. The microphone quality means the WH-CH520 also serve as a dependable headset for web meetings, and the folding hinges have held up well across weeks of being shoved into a bag. For a device at this price, that kind of all round utility is hard to argue with.
How We Test
I used the WH-CH520 for two weeks as my primary headphones for music, podcasts, and daily video calls. I tracked battery across repeated full listening days, tested the multipoint switching between a phone and a laptop, and made calls in both quiet rooms and noisy streets.
I compared them directly with the over ear WH-CH720N and checked my impressions against independent coverage. The PCMag review of the Sony WH-CH520 is a useful cross reference on where this pair sits in the budget market. The WH-CH520 listing on Amazon shows current pricing and available colors.
