Soundcore P31i vs P20i: Is ANC Worth the Upgrade?

PR / Disclosure: As an Amazon Associate I earn from qualifying purchases. Prices and availability can change.

If you are comparing the Soundcore P31i vs P20i, the decision is simpler than the model numbers suggest. The P20i is the low-cost, no-ANC option for music, podcasts, workouts and everyday listening. The P31i is the more advanced choice with real-time adaptive active noise cancellation, LDAC/Hi-Res support, six microphones and a larger official total battery figure.

Quick answer: choose the P20i if your priority is spending less and you do not need active noise cancellation. Choose the P31i if you commute, fly, work around steady background noise, take frequent calls or want LDAC on a compatible device.

Methodology: This is a specification-based buying guide, not a hands-on review. Product features were checked against Soundcore’s US product pages on September 2, 2026. Amazon.com availability and best-seller presence were checked on the same date. Battery and noise-cancellation figures are manufacturer claims measured under the brand’s conditions; real results vary by volume, codec, ANC use, calls and environment.

Soundcore P31i vs P20i: key differences

The largest practical difference is ANC. The P31i is designed to reduce continuous environmental noise, while the P20i depends on the physical ear-tip seal. The P31i also adds a more ambitious audio and call feature set. The P20i counters with a simpler product and typically a lower purchase price, although you should check the current listing rather than rely on a fixed price in this article.

Is the P31i worth upgrading to for ANC?

For commuters, frequent flyers and people who work around fans, engines or HVAC noise, the P31i has the clearer feature advantage. Soundcore markets its real-time adaptive ANC as automatically adjusting to the surrounding environment and claims noise reduction up to 52 dB.

That figure should not be interpreted as a promise that every sound becomes 52 dB quieter. ANC performance depends on frequency, fit and test method. Voices and sudden high-frequency sounds are also more difficult to suppress than steady low-frequency noise. Still, the feature difference is objective: the P31i has active noise cancellation; the P20i does not.

If you mostly listen at home, walk outdoors where awareness matters, or use earbuds as an inexpensive backup, paying more for ANC may not improve your actual use. In those cases, the P20i can be the better-value choice.

Sound quality and LDAC: what the specifications can tell us

The P31i uses 11 mm titanium-coated drivers and officially supports LDAC and Hi-Res Audio. The P20i uses 10 mm drivers and promotes boosted bass through Soundcore’s BassUp tuning. Both work with the Soundcore app, so buyers can adjust controls and sound settings rather than being locked into the default profile.

LDAC can transmit more audio data than basic Bluetooth codecs when used with a compatible source device and suitable content. It is most relevant to compatible Android devices; codec availability can differ by phone, operating system and app. LDAC alone does not guarantee that every listener will prefer the P31i, and driver size alone does not prove better sound quality. Because we did not conduct controlled listening tests, this guide does not invent a winner for tonal balance, detail or soundstage.

Battery life: the case is where the P31i pulls ahead

With ANC off, both models carry an official maximum of up to 10 hours from the earbuds. The difference is the charging case: Soundcore lists up to 50 total hours for P31i and up to 30 total hours for P20i. With P31i ANC enabled, the official figures become up to 8 hours per charge and 40 hours with the case.

The P31i also has the stronger published quick-charge claim: 10 minutes for up to 3.5 hours, compared with up to 2 hours for the P20i. These are controlled manufacturer figures. Higher volume, LDAC, ANC, microphone use and temperature can reduce real-world runtime.

Calls and connectivity

On paper, P31i is the more capable call model. It uses six microphones with an AI noise-reduction algorithm and includes a wind-noise reduction claim. P20i uses two built-in microphones with AI-enhanced voice pickup. More microphones do not automatically guarantee perfect calls, but the P31i gives its processing system more inputs to work with.

Soundcore lists Bluetooth 6.1 for P31i and Bluetooth 5.3 for P20i. Version numbers alone should not decide the purchase: stability also depends on your phone, radio environment and firmware. Both products support Soundcore’s app, while P20i’s official page specifically highlights 22 EQ presets, customizable controls, gaming mode and Find My Earbuds.

Water resistance and everyday use

P31i carries an IP55 rating, which includes both limited dust protection and protection against water jets under the relevant test standard. P20i is rated IPX5, indicating water resistance but no published dust rating in the “X” position. Both are reasonable candidates for workouts and light rain, but neither rating means you should swim or shower with the earbuds.

Fit remains personal. A secure seal affects bass, comfort and passive isolation on both models, and it also affects how well ANC can work on P31i. Use the supplied ear tips and, for P31i, Soundcore’s app-based fit tools if available for your firmware and region.

Which should you buy?

Buy Soundcore P31i if:

• You want adaptive ANC for commuting, flights or office noise.
• You use a compatible device and care about LDAC/Hi-Res support.
• You want the larger official case-assisted battery figure.
• You take frequent calls and prefer the six-microphone specification.
• You want an IP rating that also includes published dust protection.

Buy Soundcore P20i if:

• You want the lower-cost option and do not need ANC.
• You need simple earbuds for the gym, podcasts or a backup bag.
• Up to 30 total hours is enough for your routine.
• You want app EQ, customizable controls and Find My Earbuds.
• You prefer to spend the savings elsewhere rather than pay for features you may not use.

Value: compare the live price gap, not the model number

The better buy depends on the live price difference. If P31i is only modestly more expensive and you will use ANC, its added features are easier to justify. If P20i is substantially cheaper and your listening happens in quiet places, it remains the more efficient purchase.

Do not assume a newer or higher-numbered model is automatically better for every buyer. Check the current Amazon listing, seller and return terms. This article does not publish a fixed price because promotions and availability change.

Soundcore P31i vs P20i FAQ

Does Soundcore P20i have noise cancellation?

Are P31i and P20i good for workouts?

Both have water-resistance ratings suitable for sweat and light rain under the stated test conditions: IP55 for P31i and IPX5 for P20i. Fit is personal, and neither model should be treated as suitable for swimming.

Is Soundcore P31i better than P20i?

P31i has the stronger feature set, including ANC, LDAC, six microphones, more total claimed battery life and dust protection. P20i can still be the better buy when low cost and simplicity matter more than those upgrades.

Final verdict

For most buyers specifically searching for a Soundcore P31i vs P20i comparison, the decision comes down to one question: will you regularly use ANC? If yes, P31i is the more complete travel and commuting earbud. Its LDAC support, six-microphone system, IP55 rating and larger battery-case claim reinforce that choice. If no, P20i preserves the essentials—app support, customizable sound, long single-charge playback and water resistance—at a more budget-focused position.
