Sony WH-CH520 vs WH-CH720N: Which Should You Buy?
Checked 20 October 2026. Prices below are Infinite Tech catalogue snapshots in Kenyan shillings. Confirm the exact model, physical availability, package and warranty before ordering. This is a research-based buying guide using manufacturer documentation, rather than a hands-on laboratory review.
Sony WH-CH520 vs WH-CH720N is mainly about fit and noise cancellation. CH520 is KSh 6,995 and CH720N KSh 12,200, giving a checked difference of KSh 5,205. Spend it if over-ear fit, ANC or an analogue connection makes your day easier; save it if straightforward wireless listening is enough.
Neither model should be evaluated solely by a number or a battery headline quoted without its operating conditions. A fitting and a real call are more informative than assuming the larger ear cup will always feel better.

CH520 for quieter places
CH520 makes sense for music, podcasts and general phone use when ambient noise is modest. Its pads rest on the outer ear rather than surrounding it. That can feel lighter and less enclosing, but pressure may become tiring for some people. Wear it with your normal glasses during a trial.
It also keeps spending close to KSh 7,000. Bluetooth depends on a charged battery. Do not buy it expecting an analogue cable to take over when the battery is empty or a USB charging cable to carry audio.
CH720N for commuting and shared workspaces
CH720N adds ANC and an over-ear fit. Sony lists approximately 192g and up to 35 hours of music with ANC on. These specifications suit a long day on paper, but fit determines whether you will enjoy wearing it. ANC cannot erase every voice or sudden sound.
The analogue input is useful with a compatible laptop or headphone socket. Check functions in powered and passive modes, and do not assume the built-in wireless microphone travels through the audio cable. For an important meeting, test the output and microphone input separately.
Read the battery figures fairly
CH520’s up-to-50-hour claim and CH720N’s up-to-35-hour claim are not directly comparable without knowing that the latter is ANC on. Sony lists up to 50 hours for CH720N with ANC off. Calls, volume, settings and battery age can shorten those maxima.
Choose according to the mode you will use. A person working beside a fan may keep ANC on throughout the day; someone listening at home may leave it off. Confirm charging requirements and cable contents in the local package.
Make the KSh 5,205 decision
Choose CH520 if you like its on-ear fit, listen mainly in quieter spaces and value the smaller upfront cost. Choose CH720N if surrounding noise repeatedly interrupts your work and its over-ear fit is comfortable. No universal comfort ranking can replace trying them.
If both feel wrong, change physical design before stretching the budget. Our Sony earbuds guide covers smaller options. If you want bass controls or a folding premium design, compare ULT WEAR and XM5 and decide whether those extras solve a real need.
Frequently asked questions
What is the listed price difference?
CH720N adds KSh 5,205 over CH520 at this snapshot. Check current prices and local packages before budgeting.
Does CH520 have noise cancellation?
It has no active noise cancellation. Any physical reduction from its pads is different from an ANC system.
Is CH720N over-ear?
Yes. Sony specifies an over-ear design. Ear shape and glasses can still affect the seal and comfort.
Which has a longer battery headline?
CH520 is up to 50 hours. CH720N is up to 35 hours with ANC on and up to 50 off, under Sony’s stated conditions.
Can CH520 use a 3.5mm cable?
No. It has no analogue listening input. Its USB charging connection is not a headphone audio socket.
Can CH720N use an analogue source?
Yes, through its stereo mini-jack input. Check the source and distinguish headphone playback from microphone support.
Are these direct wireless PS5 headsets?
Do not assume direct PS5 Bluetooth audio support. Check a supported wired route or choose a gaming model with the required connection.
Does ANC remove nearby conversation completely?
No. Its effectiveness depends on the noise, seal and settings. It reduces some sound without producing complete silence.
Are they sweat-resistant sports headphones?
Do not assume that. Check Sony’s model-specific resistance claims and care instructions before using everyday headphones for exercise.
What is the best comparison test?
Wear both with your glasses, listen comfortably, compare available modes and make a call through your own device.
