Soundcore P40i by Anker

Product Details

The Soundcore P40i is an in-ear wireless earbud set designed for people who want long battery life and heavy bass. It comes in a black finish, fits securely inside the ears, and has a lightweight yet sturdy design.

The case is unique because it doubles as a phone stand. That feature alone makes it different from most earbuds in this price range.

The earbuds have an impedance of 14 Ohm, which works well with smartphones and tablets. They don’t need extra amplification, so they are friendly to casual listeners.

Features

Adaptive Noise Cancelling

The P40i has adaptive ANC. This means it listens to outside noise through built-in microphones, then adjusts cancellation levels automatically. For example, on a train ride, it will focus on lowering engine hum. On a busy street, it targets car horns and voices. This makes daily listening smoother without needing to switch modes manually.

Long Battery Life

Battery life is one of the P40i’s strongest selling points. The earbuds alone last up to 12 hours per charge. With the case, total playtime extends to 60 hours. For most users, this means you only need to charge once every week or two. For light users, the battery can even last close to a month.

This level of endurance is rare in earbuds. It makes the P40i especially useful for long trips, camping, or people who dislike frequent charging.

Bass-Heavy Sound

The P40i uses 11mm composite drivers. Combined with BassUp technology, they deliver strong, punchy bass. The low frequencies stand out clearly. Music like hip-hop, EDM, or dance feels powerful and immersive.

The bass is not subtle. It’s designed for impact, not balance. Listeners who want soft, neutral sound may find it too strong.

Call Quality

With 6 microphones and AI noise reduction, the P40i improves call clarity. Your voice sounds clean even in a crowded area. For video calls, it also reduces background noise so others hear you clearly.

Unique Charging Case

The case doubles as a phone stand. This is practical for people who watch videos on their phones while using earbuds. Place your phone on the stand, sit back, and enjoy shows without holding your device.

What is the Good?

• Very long battery life: up to 60 hours with case.

• Strong bass performance: great for bass lovers.

• Good call clarity: 6 mics with AI processing.

• Convenient case stand: watch videos hands-free.

• Adaptive ANC: automatic adjustment for noise levels.

What is the Bad?

• Sound is bass-heavy, not ideal for classical or balanced listening.

• No advanced audio codec like LDAC for Hi-Res audio.

• Case is slightly bulkier than standard ones.

• No IPX water resistance rating, less safe for workouts.

Overall Opinion

The Soundcore P40i is designed for practical everyday users. It fits best for people who want long battery life, loud bass, and simple call clarity. The unique case stand is a fun bonus.

On the other hand, it doesn’t focus on detailed sound or premium features. It is a strong choice for students, commuters, or travelers who want durability and simple convenience.

Features

Strong Noise Cancelling

The Liberty 4 NC cancels up to 98.5% of outside noise. It uses Adaptive ANC 2.0, which makes real-time adjustments based on your ear canal and the environment.

On a flight, it lowers jet engine noise effectively. On a busy street, it reduces cars and chatter. In a café, it cancels clinking dishes. This makes it one of the most effective ANC systems in its price range.

With 11mm custom drivers, LDAC support, and Hi-Res wireless certification, the Liberty 4 NC delivers crisp and detailed audio. Vocals sound clear, instruments stand out, and the overall sound feels richer compared to the P40i.

Personalized Sound Profiles

The HearID 2.0 system scans your hearing and builds a personal EQ. Everyone hears differently, and this feature ensures the sound matches your ears. You can also pick from 22 presets or create custom EQ profiles. This level of control is rare and appeals to users who enjoy tailoring sound.

Battery Life

The Liberty 4 NC lasts 10 hours per charge with ANC off and 8 hours with ANC on. The case extends this to 50 hours or 40 hours with ANC on. This is solid but slightly lower than the P40i.

Smart Connections

It supports Bluetooth 5.3, multipoint pairing, and quick auto-pairing. Multipoint allows you to connect to two devices at the same time, such as a laptop and phone.

Water Resistance

The Liberty 4 NC has an IPX4 rating, which protects it from sweat and light rain. This makes it safer for workouts or outdoor use compared to the P40i.
