Head-to-head
Soundcore Space One Pro vs Sony WH-CH730N: Sony is lighter and has verified passive backup
The short answer
Choose Sony WH-CH730N if lower weight, a longer ANC battery claim and verified battery-free cable playback are your priorities. Choose Soundcore Space One Pro if its compact FlexiCurve fold or LDAC support matters more. Both offer ANC and two-device multipoint, but those features do not establish equal noise reduction or call quality.

Winner by situation

Weight is the main travel constraint
Sony is 79.2 g lighter according to the manufacturer weights.

Your headphone battery sometimes runs flat
Sony explicitly documents passive playback. An analog input alone does not establish the same behavior on Soundcore.

You use LDAC from a compatible phone
Soundcore supports LDAC, while Sony lists SBC, AAC and LC3 instead.

What matters in practice
The differences that matter
Sony is about 28% lighter
WH-CH730N saves 79.2 g against Space One Pro, a substantial physical difference worth trying on.
How we reached this conclusion
(286.2 - 207) / 286.2 × 100 = 27.7%. Published headphone weights are used, not shipping weights.
The ANC-on rating is 25% longer
Sony claims 50 hours with ANC against Soundcore's 40 hours.
How we reached this conclusion
(50 - 40) / 40 × 100 = 25%. These are manufacturer maxima under their own test conditions.
A five-day workload exposes the charging margin
At an illustrative eight hours per day for five days, the rated workload is 40 hours. Soundcore matches that number, while Sony has 10 rated hours above it.
How we reached this conclusion
5 × 8 = 40 hours. 50 - 40 = 10 hours. This arithmetic does not guarantee a charge-free week.
Check your own setup
Which headphones work with the way you listen?
Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.

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
soundcore, Space One Pro
Space One Pro
A travel-focused ANC pair with a segmented headband that folds into a tighter shape. Its ANC-on battery rating matches Space One at 40 hours.
- Best matched use
- Packing full-size ANC headphones into a crowded bag
Checked facts
- The official ANC-on rating is 40 hours, rising to 60 hours without ANC.
- The listed weight is 286.2 g.
- The FlexiCurve headband has five folding segments and supports multipoint.
Choice B
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.
Meaningful differences
What changes the fit
| What changes | soundcore Space One Pro | Sony WH-CH730N | Why it matters |
|---|---|---|---|
| Headphone weight | 286.2 g | 207 g | Sony removes 79.2 g from the stated headphone mass. |
| ANC-on battery claim | 40 hours | 50 hours | Sony claims 10 more hours in the relevant noise-canceling mode. |
| ANC-off battery claim | 60 hours | 75 hours | The battery advantage remains 25% using the other published mode. |
| Folding | Five-part FlexiCurve fold | Folds inward | Both fold, but packed shape is different and should be checked against your bag. |
| Higher-bandwidth Bluetooth option | LDAC | LC3, no LDAC listed | The phone and selected Bluetooth mode must support the desired codec. |
| Passive analog playback | Not verified here | Verified with power off | Only Sony is a confirmed dead-battery recommendation in these records. |
| Two-device connection | Multipoint | Multipoint | Neither needs to be chosen solely to keep a laptop and phone connected. |
What you give up
Every choice has a cost
If you choose soundcore Space One Pro
- The 60-hour headline rating is with ANC off.
If you choose Sony WH-CH730N
- The supported codec list has LC3 but not LDAC, and LC3 needs a compatible source.
Recommendation switch
The decision flips if...
You want the compact FlexiCurve folding layout.
Choose soundcore Space One Pro. Space One Pro uses Soundcore's FlexiCurve arrangement to pack the cups and headband together. WH-CH730N also folds, so folding alone is not an exclusive feature. Use case dimensions and the actual bag compartment before treating the more elaborate hinge design as a reason to buy.
You want the lighter 207 g headphone.
Choose Sony WH-CH730N. Lower published weight, a 50-hour ANC claim and documented passive cable operation all address everyday travel friction. The passive mode matters when the battery is empty, but it does not preserve powered noise cancellation.
What matters in practice
How to make the call
Choose the folding system for your bag
Space One Pro uses Soundcore's FlexiCurve arrangement to pack the cups and headband together. WH-CH730N also folds, so folding alone is not an exclusive feature. Use case dimensions and the actual bag compartment before treating the more elaborate hinge design as a reason to buy.
Sony has the clearer low-maintenance travel case
Lower published weight, a 50-hour ANC claim and documented passive cable operation all address everyday travel friction. The passive mode matters when the battery is empty, but it does not preserve powered noise cancellation.
The codec decision depends on the phone
LDAC is a valid reason to shortlist Soundcore only if your source supports it and you want that mode. Sony's LC3 also requires a compatible source and mode. Neither codec name ranks the underlying headphone tuning or proves an audible improvement for every listener.
What this comparison cannot tell you
- No measured ANC, call quality or tonal ranking is claimed.
- Soundcore passive analog operation remains unknown in this comparison, rather than being treated as unsupported.
