Soundcore P31i vs Soundcore Space One: Which Noise-Cancelling Option Fits You?

Space One rate higher for usability and setup, and customer feedback commonly describes them as comfortable and easy to connect, including use across more than one device. Physical buttons can also feel more predictable than touch controls for some users.

P31i get strong satisfaction overall, but usability is a more mixed area. Reviews mention that touch control placement can be easy to trigger when adjusting fit, and some users report initial connection/setup friction (with at least one reviewer noting that firmware/app setup improved the experience).

Design is primarily a form-factor choice here. P31i are compact, in-ear, and easy to carry, with a much lower weight listed. They can be a better day-to-day carry option, but fit can vary by ear shape, which shows up in mixed feedback.

Space One use an over-ear design with rotating ear cups and a soft headband for long wear. Reviews often praise comfort, but also note the headset can look and feel bulky compared with earbuds. If you plan to wear them for hours at a desk or on flights, Space One’s design focus is a key advantage.

Both products score similarly for build quality, with some recurring “value build” language in customer feedback. P31i are described as a good value and durable by some reviewers, but there are also concerns about the charging case feeling slick and questions about how well the lid will hold up to drops.

Space One also receive “plasticky” build comments, and a few reviews mention housing texture/rubbing noise in certain positions and concerns about pad removability/cleaning. If you’re hard on gear, P31i’s IP55 rating helps for moisture exposure, while Space One’s included case helps for transport protection.

Durability leans toward P31i for everyday exposure because they are rated IP55, and one reviewer even reported an accidental water drop incident without failure. That said, case durability is a concern in some feedback (slick plastic and worries about the lid after a hard hit).

Space One are not water resistant, which can limit how carefree you can be with them outdoors. Reviews also mention wear-related concerns like pad cleaning/replacement difficulty and discoloration on lighter colors.

Soundcore P31i are the clear portability winner: they’re in-ear earbuds with a compact charging case and a much lower listed weight. They also score very high for portability, making them better for pockets, small bags, and always-on-hand carry.

Soundcore Space One are over-ear and significantly heavier, with reviews describing them as bulkier. The included protective case helps with travel, but they’re still a larger item to pack and carry.

Soundcore P31i offer a notably broader feature mix for earbuds: adaptive ANC, LDAC, spatial audio, fast charging, IP55 water resistance, and an explicit real-time AI translation capability (100+ languages) that runs through the Soundcore app. They also emphasize call features with six AI-enhanced mics and wind-noise reduction.

Soundcore Space One focus on core headphone features: adaptive ANC tuned for voice reduction, LDAC Hi-Res wireless, app control, and long battery life. They also ship with travel-friendly extras (AUX cable and protective case), which can matter if you want a wired option on planes or with devices that benefit from a cable.

Both rely on the Soundcore app for customization (EQ, ANC modes, and related settings). Space One score higher for app experience and reviews mention helpful setup features like EQ customization.

P31i also use the app heavily, especially for translation and fine-tuning. Review feedback suggests that app setup and firmware updating can be important to get the best connectivity and overall experience, which can feel like extra work if you want a plug-and-play pair.

P31i score higher for smart features largely due to their explicit AI translation capability and app-driven modes like adaptive ANC and spatial audio. If you want earbuds that do more than the basics, this is a key advantage.

Space One focus more on the core listening experience—ANC, EQ/app control, and comfort—rather than a long list of “smart” extras. They still have app control, but the feature emphasis is simpler.

Space One score higher for setup, aligning with reviews that describe easy connection and straightforward use. The included accessories (case and AUX cable) can also simplify getting started for travel.

P31i setup is more variable. Some users connect easily, while others report early connection issues and recommend completing first-use steps (app download and firmware update) to stabilize the experience.

Both support common devices like phones and computers, but Space One list the broadest compatibility set in the provided specs (including gaming consoles) and score higher for compatibility. They also include an AUX cable, which can improve compatibility in situations where Bluetooth isn’t ideal (for example, some travel and wired use cases).

P31i list compatibility with cellphones, laptops, and tablets and have strong app-driven features, but may require more attention to setup for best results.

Audio is close on scoring: both products earn strong audio quality scores and both support LDAC for Hi-Res wireless listening. In reviews, P31i are commonly praised for clear sound with well-balanced treble/bass, with some users comparing favorably to more expensive earbuds while still acknowledging premium models can sound better.

Space One are also widely praised for sound quality and bass in day-to-day listening. A few reviewers note they may not match the bass emphasis of some premium competitors, but still describe the overall quality as strong for the price. If you listen for long stretches, the over-ear comfort of Space One can indirectly improve perceived sound by reducing fit fatigue.

Space One have the stronger connectivity score, and customer feedback often mentions easy connection and practical use across multiple devices. They list Bluetooth 5.3 and a 15-meter range in the provided specs.

P31i list Bluetooth 6.1, but the connectivity score is lower and reviews are more mixed—some find pairing easy, while others report connection issues or a more finicky initial setup. If stable day-to-day connectivity is your top concern, Space One look safer based on the score and aggregated review themes.

Both are standouts for battery life, but they win in different ways. P31i are rated for up to 10 hours per charge and 50 hours with the case (or 8/40 with ANC on), and also include a fast-charge claim (10 minutes for 3.5 hours). Space One are rated for 40 hours with ANC on and 55 hours with ANC off, with a 2-hour charge time listed.

If you want maximum total runtime in a pocketable kit, P31i lead. If you want over-ear comfort with long ANC-on endurance, Space One deliver.

Both score strongly for power efficiency and battery life, with long rated runtimes that align with customer feedback about not needing to charge often. P31i combine efficient earbuds with a charging case, which can reduce how often you need an outlet during the week. Space One emphasize long ANC-on playtime for over-ears, which is a key benefit for commuters and frequent travelers.

Both products are positioned as strong value choices, and both score very highly for value. P31i edge this category in scoring and customer themes, combining LDAC, strong ANC, very long total battery life, IP55 water resistance, and translation features at a lower listed price.

Space One remain excellent value if what you’re buying is comfort-first over-ear listening with strong ANC, long battery life, and included accessories. Value here is less about price alone and more about matching the form factor to your routine.

This is essentially a draw: both are Soundcore (Anker) products and carry the same brand trust score. Reviews for both products frequently frame Soundcore as delivering strong performance for the money, and both products show high overall customer satisfaction. If brand trust is your deciding factor, the bigger differentiators are form factor, features, and the specific reliability notes in reviews.

Both products score highly for customer satisfaction, with strong Amazon star ratings and substantial review volume. P31i have slightly higher satisfaction scoring and a 4.5/5 average rating, with repeated praise for sound, ANC, battery, and value—balanced by mixed fit and connectivity comments.

Space One have a very large review count and a 4.4/5 rating, with consistent praise for comfort, sound, ANC, and battery. The notable downside in aggregated feedback is occasional reports of the headphones stopping working, which can impact long-term satisfaction for some buyers.

Warranty/support detail is limited in the provided data, but the scoring indicates Space One have a slightly higher warranty/support score than P31i. Because exact terms aren’t provided, it’s smart to confirm return windows and support process at purchase—especially given the mention of occasional unit failures in Space One reviews and connectivity/setup friction in some P31i feedback.
