I like wireless headphones that let me adapt the setup to an ordinary day. The soundcore Space One interests me because it combines active noise cancellation, app-based adjustments and more than one connection option. I would consider it when those choices solve a real listening problem, rather than buy it simply because the feature list is long.
Quick verdict
I would shortlist it for useful ANC and app control when the phone and connection choices are understood.
Best for: Someone who wants configurable wireless listening and will use a few settings deliberately.
Main benefit: ANC,app adjustments and an optional audio cable provide several practical connection roles.
Biggest drawback: LDAC requires a supported source and does not operate with the documented two-device connection arrangement.

Reviewed version: soundcore Space One A3035,original generation,black
Compatibility: Correct A3035 model,current soundcore app and compatible Bluetooth source. iPhone/iPad do not use LDAC; check wired-mode controls and microphone limits.
Review context: I assess current maker support and model-specific connection documentation; no listening,battery or ANC result is claimed.
The selected model is the original black Space One, A3035. It is not Space One Pro. I would check that model number before comparing offers or borrowing an accessory recommendation, because a similar family name does not make every feature and physical part interchangeable.

Noise cancellation needs the right fit
The selected maker information describes adaptive ANC and adjustable sound modes. I like having a choice when the environment changes between a desk and a journey. I would still begin with pad fit and a comfortable headband position, because electronics do not remove the importance of how the headphones sit.
A marketing reduction percentage is not a result from this review or a promise about every sound. I would compare the product in its intended setting and judge whether it addresses the actual annoyance. A steady background hum and a nearby conversation are different things to ask a headphone to manage.
I would also learn the difference between ANC and the mode that lets surrounding sound through. The useful setup is one whose current state is easy to recognise. Automatic features can be convenient, but I still want a clear manual way to select the behaviour I need.
The app is part of the product
soundcore’s official A3035 support page provides the model’s guide. I like being able to check the actual instructions instead of treating a general headphone tutorial as sufficient. Settings, firmware and control options should come from the selected model’s documentation.
I would begin with a small number of useful adjustments. A familiar playlist, a comfortable volume and one deliberate EQ change are easier to understand than activating several features at once. The point is enjoyable listening, rather than creating a complicated configuration that is difficult to reproduce later.
The app and phone support also belong in the buying decision. I would verify that the intended phone can run the current software before paying mainly for customisation. A feature that depends on an app is less attractive when that app does not fit the person’s normal device arrangement.

LDAC and multipoint are different priorities
The maker supports LDAC with compatible sources, but it is not a universal Bluetooth feature. The official Anker A3035 information explains that iPhone and iPad do not use LDAC and that its use has connection conditions. I would check the actual source rather than assume the codec badge benefits every phone equally.
The documented model also requires a choice between LDAC and a two-device connection. I like having both possibilities available, while keeping that trade-off visible. For a phone-and-laptop day, easy switching may be more valuable than selecting a particular music codec.
I would choose for the task and leave the setting alone when it works. A codec name does not by itself establish an audible improvement for every recording or listener. The more useful question is whether the complete arrangement is stable, convenient and enjoyable for the material being played.
Wired use is its own mode
The supplied audio lead gives the headphones another practical connection route. I like that option for a suitable source, but I would read the wired-mode instructions before assuming every Bluetooth control and microphone function carries across unchanged.
Anker’s model information distinguishes the available wired features from wireless operation. I would plan the microphone separately when a wired call setup is required. A cable in the box does not automatically turn a wireless headphone into every kind of wired headset.
For me, the useful cable arrangement is one that serves an actual source. I would not carry extra adapters merely to make a theoretical feature available. A simple setup with one clearly understood spare connection is more attractive than a bag of accessories whose compatibility remains uncertain.
Battery claims describe a set of conditions
The selected listing advertises up to 40 hours with ANC and up to 55 hours without it. Those are manufacturer figures, not operating-time results from this review. I would choose the features I actually want and expect the charging routine to depend on those choices, volume and use.
LDAC can also change the power relationship. I would not combine the largest battery figure with a different feature arrangement and present the result as guaranteed. A useful specification keeps its conditions attached instead of becoming one unusually optimistic number.
USB charging is straightforward to plan around a desk or travel bag. I would keep a suitable lead available and give the headphones a normal return-and-charge place. The attractive benefit is less interruption, with an ordinary habit that prevents an avoidable low-battery surprise.

My alternatives and buying view
I would compare the Sony WH-CH720N for another lightweight over-ear ANC direction. The ATH-M40x makes more sense when a direct wired monitoring setup is the real task. I would shortlist Space One for someone who wants useful app control and understands the connection choices.
I like the flexibility. I would buy the original A3035 for a few features that will be used regularly, with fit and phone compatibility checked, rather than assume every advertised setting can or should run together.

What worked
ANC,app adjustments and an optional audio cable provide several practical connection roles.
What bothered me
LDAC requires a supported source and does not operate with the documented two-device connection arrangement.
Who should not buy it
I would choose another setup when universal LDAC support or an unchanged wired microphone workflow is required.
Alternatives I would consider
Sony WH-CH720N. I would compare another over-ear ANC arrangement and its app. Read my Sony WH-CH720N review.
Audio-Technica ATH-M40x. I would choose its direct wired approach for a fixed monitoring task. Read my Audio-Technica ATH-M40x review.
Evidence and sources
Product details come from the cited sources. Images come from the selected product gallery and any explicitly credited manufacturer material. They are not personal test photographs or measurements.
Features, compatibility and rated figures from the maker are manufacturer information. My opinions are identified in the review.
Conclusion
Worth considering for regularly used features; judge fit and the actual phone rather than a collection of codec badges.
