Adaptive ANC
The P31i uses real-time adaptive noise cancellation that can reduce environmental noise by up to 52 dB according to Soundcore.

How Good Is the ANC?
Active noise cancellation is one of the main reasons to consider the P31i.
Soundcore says its adaptive ANC can reduce noise by up to 52 dB and automatically adjust the cancellation level based on your surroundings. :contentReference[oaicite:2]{index=2}
In practical terms, adaptive ANC is particularly useful for environments such as public transport, offices, cafés and other places with changing background noise.
Keep in mind that advertised noise-reduction figures are manufacturer measurements. Actual results vary with ear fit, ear-tip seal and the surrounding environment.
Sound Quality
The P31i uses 11 mm titanium-coated drivers. Soundcore describes the tuning as delivering deep bass alongside detailed treble. :contentReference[oaicite:3]{index=3}
The inclusion of LDAC is particularly interesting for listeners using compatible Android devices or other supported hardware, because it enables higher-resolution Bluetooth audio.
Best for: listeners who want a feature-rich wireless earbud with strong bass, adaptive ANC and higher-resolution Bluetooth audio support.
Battery Life & Charging
Battery life is another major strength of the P31i.
| ANC Off | Up to 10 hours per charge |
|---|---|
| ANC Off + Case | Up to 50 hours total |
| ANC On | Up to 8 hours per charge |
| ANC On + Case | Up to 40 hours total |
| Quick Charge | 10 minutes can provide up to 3.5 hours of listening |
These are Soundcore's stated laboratory figures; actual battery life depends on volume, codec, ANC usage and other conditions. :contentReference[oaicite:4]{index=4}
Call Quality
The P31i uses six microphones together with AI-based noise reduction. Soundcore says the system is designed to separate the user's voice from surrounding noise and reduce wind interference. :contentReference[oaicite:5]{index=5}
That makes the P31i particularly interesting for people who use earbuds for work calls, commuting, outdoor conversations or frequent voice communication.
AI Translation: The Interesting Extra
One of the more unusual features of the P31i is its AI translation capability.
Soundcore says the system supports translation across more than 100 languages and is designed for real-time communication. :contentReference[oaicite:6]{index=6}
This feature could make the P31i especially interesting for travelers, international students, multilingual workplaces and people who regularly communicate across languages.
Translation features can depend on the companion app, device, language support and network/software conditions, so buyers should check the current Soundcore app compatibility before relying on it for an important use case.
Bluetooth & Connectivity
The P31i supports Bluetooth 6.1 and SBC, AAC and LDAC codecs according to Soundcore's product information. :contentReference[oaicite:7]{index=7}
It also supports dual connections, allowing the earbuds to work with more than one connected device in supported situations. :contentReference[oaicite:8]{index=8}
Is the Soundcore P31i Good for Workouts?
The P31i carries an IP55 rating, which provides protection against dust and water. :contentReference[oaicite:9]{index=9}
That makes it suitable for everyday active use, including workouts and light exposure to rain. However, an IP55 rating does not mean the earbuds are designed to be submerged in water.
