Anker’s Soundcore line has become one of the most reliable names in budget earbuds, and the P31i and P40i are two of its most popular models. They sit close in price and share a lot of the same DNA, which makes Soundcore P31i vs P40i one of the most common budget-earbud questions shoppers search. Here’s how they actually differ, and which one fits your use case better.
Quick Answer
If you want the better overall daily-use pick with stronger ANC and typically the lower price, go with the P31i. If your priority is maximum battery life, wireless charging, and phone-stand functionality for long trips, the P40i is the better fit.
Soundcore P31i vs P40i: Spec Comparison
| Spec | Soundcore P31i | Soundcore P40i |
|---|---|---|
| ANC Type | Adaptive | Adaptive |
| Battery (Earbuds + Case) | Around 40-50 hrs combined | Up to 60 hrs combined |
| Wireless Charging | No | Yes |
| Case Extra Feature | Standard case | Doubles as phone stand |
| Driver | Composite driver | 11mm composite driver, BassUp |
| Typical Price | ~$40-50 | ~$45-60 |
Battery Life
This is where the P40i pulls ahead clearly. With up to 60 hours of combined playtime versus the P31i’s roughly 40-50 hours, the P40i is the better choice if you travel frequently or simply don’t want to think about charging for weeks at a time. The P40i’s case also supports wireless charging, which the P31i lacks — a meaningful convenience if you already use charging pads at home or work.
Sound Quality
Reviewers generally rate the P31i’s sound as more balanced and refined out of the box, with several comparisons noting it holds up well even against pricier earbuds. The P40i leans heavier into bass by default thanks to its BassUp tuning, which some listeners love and others find overdone without EQ adjustments through the Soundcore app.
ANC Performance
Both models use adaptive ANC that adjusts to ambient noise in real time, and performance is fairly close between them. The P40i has a slight edge for long-haul travel and consistent low-frequency noise like airplane cabins, while the P31i performs comparably for everyday environments like offices, commutes, and gyms.
Comfort & Design
Both earbuds use a similar in-ear silicone-tip design and feel light for extended wear. The P40i’s case is slightly more compact despite its phone-stand feature, while the P31i keeps things simpler with a standard case shape.
Price
Pricing between the two fluctuates with frequent Anker sales, but the P31i is typically the more affordable of the two, sometimes by a meaningful margin during promotions. If budget is the deciding factor and you don’t need wireless charging or the extra battery buffer, the P31i is the better value.

Which Should You Buy?
- Choose the P31i if: you want the best all-around value, slightly more refined sound, and don’t need wireless charging
- Choose the P40i if: you’re a frequent traveler, want the longest possible battery life between charges, or specifically want wireless charging and the phone-stand case
Frequently Asked Questions
Is the P40i worth the extra cost over the P31i? It depends on your priorities. If wireless charging and maximum battery life matter to you, yes. If you mainly want reliable daily-use earbuds at the lowest price, the P31i covers most needs just as well.
Which has better call quality, P31i or P40i? Both perform similarly for calls in quiet-to-moderate environments; neither is a standout for noisy environments compared to earbuds designed specifically around call clarity.
Can I use either with both Android and iPhone? Yes, both are fully compatible with iOS and Android through standard Bluetooth pairing and the Soundcore companion app.
Does the P40i’s phone stand case actually matter day to day? It’s a nice bonus for video calls or watching content hands-free, but it’s a secondary feature — most buyers choose between these two models based on battery life and price rather than the phone stand.
