Choose between two Sony headphone designs using verified connection, battery and weight specifications, then compare the offer available to you.
Start with the feature you need most
For a noisy commute, the CH720N’s active noise cancellation is a reason to investigate it. For a quiet desk, the CH520’s smaller on-ear cups may suit your routine. Comfort remains personal: a lighter pair can still press on your ears, while an over-ear pair may take more room in your bag.
| Feature | Sony WH-CH720N | Sony WH-CH520 |
|---|---|---|
| Fit | Over-ear | On-ear |
| Manufacturer-listed weight | About 192g | About 147g |
| Music playback claim | Up to 35 hours with noise cancelling on; 50 hours with it off | Up to 50 hours |
| Analogue cable connection | Stereo mini-jack input; detachable cable | No audio input; no passive operation |

Sony WH-CH720N: for noise cancellation and an audio cable
This is the option to examine if you need noise cancellation and also want an analogue connection. That second feature can matter when a device offers a headphone socket but no convenient Bluetooth connection.
Check the device you will plug it into. An audio connection alone does not establish microphone support for a console or work call. Avoid buying on the word “wireless” if your main use depends on a specific wired setup.
Fit check: If you wear glasses, consider where the cushion will meet the frame. We cannot judge clamping pressure, seal or comfort from the specification sheet.
Sony WH-CH520: for an on-ear wireless setup
The CH520 can connect to two Bluetooth devices at once, according to Sony’s feature page. That is worth considering if you use a laptop for listening and keep your phone nearby for calls.
Connection limitation: Plan around Bluetooth. A USB charging cable is not evidence of USB audio support, and this model is unsuitable if a passive analogue connection is essential to you.
Fit check: On-ear pads rest against the ears. If that position has bothered you before, do not let a smaller design or a discount outweigh that experience.
Compare battery claims on the same basis
The CH720N has separate figures for listening with noise cancellation switched on and off. Use the setting you expect to use when comparing it with the CH520. Call time, volume and daily use can produce different results from an advertised music-playback maximum.
Decide whether the price difference is justified
Open both product links and select the colour you would actually buy. Note the payable amount after only the coupons or payment offers you can use. If the CH720N costs more, decide whether noise cancellation and the cable option solve a regular problem for you. If they do not, spending the difference may bring little benefit to your routine.
Check the listing’s return or replacement terms before treating an online order as a home trial. A policy that covers defects may not cover disliking the fit. Also confirm who supplies the warranty and which accessories come with the selected variant.
Our buying recommendation
Shortlist the CH720N when noise cancellation or a headphone-socket connection is a priority. Shortlist the CH520 when you want an on-ear Bluetooth pair and its connection limitations work for you. The final choice should follow your use case and the actual price gap; this comparison does not establish a winner for sound or microphone quality.
