Main trade-off
Sony WH-CH730N
It is 15 g heavier than the CH720N.
Head-to-head
Sony WH-CH730N vs WH-CH720N: CH730N folds, CH720N weighs less
The short answer
Choose WH-CH730N for folding storage and fewer charging stops. Choose WH-CH720N if the lightest frame matters more. Both offer multipoint and a passive analog cable, so those are not reasons to pay for the newer model.
Before you choose
The reasoning and the trade-offs
Fifteen more rated ANC hours
CH730N has a 42.9% higher ANC playback claim than CH720N.
What this is based on
(50 − 35) ÷ 35 × 100 = 42.9%. Both figures use Sony’s ANC-on music-playback specification.

Winner by situation
Start with what you need it to do
I listen six hours on each weekday
That is 30 hours of listening. CH730N leaves 20 rated hours above that schedule, compared with five on CH720N. Real runtime can be lower.
- Sony WH-CH730N
- Better fit
- Sony WH-CH720N
- Good
I am sensitive to headset weight
CH720N is 15 g lighter. Try both because clamp and pad shape still matter.

I pack my headphones every morning
The new folding hinge is relevant every time the headphones go into a crowded bag.

I need a laptop and phone connection
Multipoint is present on both, so it does not favor the newer model.

What matters in practice
The differences that matter
Fifteen more rated ANC hours
CH730N has a 42.9% higher ANC playback claim than CH720N.
How we reached this conclusion
(50 − 35) ÷ 35 × 100 = 42.9%. Both figures use Sony’s ANC-on music-playback specification.
A five-day schedule shows the difference
At six hours per weekday, the published claims leave 20 hours of margin on CH730N and five on CH720N.
How we reached this conclusion
5 × 6 = 30 hours. 50 − 30 = 20 and 35 − 30 = 5. Margins are arithmetic on rated limits, not guaranteed remaining battery.
The lighter choice is still CH720N
CH730N weighs 7.8% more than CH720N.
How we reached this conclusion
(207 − 192) ÷ 192 × 100 = 7.8%.

Meets these checksBluetooth listening.
Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.
Choice A
Sony, WH-CH730N
WH-CH730N
The useful upgrade from the CH720N is straightforward: a folding frame and a 50-hour ANC claim. It adds 15 g, so the older model still wins if minimum weight matters most.
- Best matched use
- A week of commuting with a folding pair
Checked facts
- Rated up to 50 hours with noise cancellation and 75 hours with it off.
- Approximate headphone weight is 207 g.
- Supports a detachable 1.2 m analog cable and passive operation.
- Multipoint and SBC, AAC and LC3 are listed in Sony specifications.
Choice B
Sony, WH-CH720N
WH-CH720N
A sensible starting point when you want noise cancellation without a heavy headset. Its 192 g frame is lighter than the CH730N, though it does not fold inward for packing.
- Best matched use
- Low-weight noise-canceling listening
Checked facts
- Approximate headphone weight is 192 g.
- Rated up to 35 hours with noise cancellation and 50 hours with it off.
- The analog cable is detachable and passive playback is supported.
- Supports two-device multipoint and SBC or AAC audio.
Meaningful differences
What changes the fit
| What changes | Sony WH-CH730N | Sony WH-CH720N | Why it matters |
|---|---|---|---|
| Weight | 207 g | 192 g | The longer battery claim comes with 15 g more weight. |
| ANC playback claim | Up to 50 hours | Up to 35 hours | The difference is 15 rated hours with noise cancellation enabled. |
| ANC-off playback claim | Up to 75 hours | Up to 50 hours | Neither ANC-off number should be used for a noise-canceling flight estimate. |
| Packing | Folds inward | Does not fold inward | CH730N adds a useful travel change rather than only a specification bump. |
| Passive analog | Supported | Supported | Both still work from an analog source with their batteries depleted. |
| Two-device multipoint | Supported | Supported | Both can cover a phone and laptop. |
| Bluetooth codecs | SBC, AAC, LC3 | SBC, AAC | LC3 needs a compatible LE Audio source. Neither list includes LDAC. |
What you give up
Every choice has a cost
If you choose Sony WH-CH730N
- The supported codec list has LC3 but not LDAC, and LC3 needs a compatible source.
If you choose Sony WH-CH720N
- USB-C is for charging and the Bluetooth codec list does not include LDAC.
What matters in practice
How to make the call
The new hinge changes the daily routine
A longer battery claim is easy to understand, but the folding frame can matter more if you carry the headphones in a small bag. CH720N turns flat without folding inward. CH730N adds a clear packing option that the old design lacks.
Use the ANC figure for a train or flight
The prominent 75-hour figure belongs to CH730N with noise cancellation off. Compare 50 against 35 hours when your reason for buying is a noisy journey. Those are still maximum claims, with actual results depending on volume, calls and settings.
The connection upgrade has a condition
LC3 is an additional option rather than a universal sound upgrade. A compatible LE Audio source is required. Both retain an ordinary passive analog fallback and multipoint, which will be more relevant than the codec list for many buyers.
What this comparison cannot tell you
- The battery margins are planning comparisons, not forecasts of charge remaining.
- This comparison does not claim that one model cancels a measured amount more noise.
