Soundcore P40i vs Liberty 4 NC: Battery, LDAC, Gaming and Water Resistance
P40i is the practical value-fit choice for longer rated battery, faster rated quick charging, lower Game Mode latency, IPX5 protection and its phone-stand case. Liberty 4 NC is the better fit for LDAC-capable listening and its Adaptive ANC 2.0 feature set. RTINGS describes overall performance as similar with mostly minor differences, so neither model is a universal upgrade.

The buying question
Do Liberty 4 NC's LDAC and travel-oriented feature set justify choosing it over P40i's longer rated battery, lower Game Mode latency, phone-stand case and higher water-resistance rating?
Liberty 4 NC adds LDAC and Adaptive ANC 2.0, while P40i emphasizes battery, fast charging, Game Mode latency and its IPX5 phone-stand case; the available bilateral test finds their overall performance broadly similar.
Quick verdict
Choose Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC if
- You want up to 12 hours per charge and 60 hours with the case in the manufacturer's stated normal-mode figures.
- You play games or watch video and value the significantly lower Game Mode latency reported by RTINGS.
- You need IPX5 protection or want a charging case that doubles as a phone stand.
Choose Soundcore by Anker Liberty 4 NC Wireless Earbuds if
- Your phone and music service support LDAC and you will use that codec.
- You prefer Liberty 4 NC's Adaptive ANC 2.0 controls and will use its LDAC feature set.
- The shorter rated battery is acceptable in exchange for the Liberty feature set.
When the recommendation changes
- The current Amazon offer gap changes materially at review time.
- A controlled test with the buyer's fit, phone and firmware changes the broad-similarity result.
- The buyer requires a codec or device compatibility that the available sources do not verify.
- The buyer's priority shifts from gaming and water exposure to high-bitrate Bluetooth playback.
The differences that matter
Overall Anc And Audio Performance
Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
RTINGS says P40i and Liberty 4 NC perform similarly with mostly minor differences; P40i is the exact model tested under the name Soundcore P40i.[3]
Soundcore by Anker Liberty 4 NC Wireless Earbuds
RTINGS says Liberty 4 NC and P40i perform similarly with mostly minor differences; Liberty 4 NC is the exact model tested under the name Anker Soundcore Liberty 4 NC Truly Wireless.[3]
What this changes: The available bilateral evidence supports choosing by feature fit rather than treating either earbud as an across-the-board ANC or sound-quality winner.[3]
Gaming And Video Latency
Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
RTINGS reports significantly lower latency for P40i when Game Mode is used; the public comparison summary does not expose a numeric latency value.[3]
Soundcore by Anker Liberty 4 NC Wireless Earbuds
Liberty 4 NC is not the lower-latency option in RTINGS' Game Mode comparison; no numeric value is exposed in the public summary.[3]
What this changes: P40i is the evidence-backed feature fit for buyers who notice lip-sync or game timing and will enable Game Mode. This does not establish a universal latency result for every device or app.[3]
Codec And Personalized Audio
Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
Soundcore lists P40i with 11mm composite drivers, adaptive ANC, BassUp and HearID app support; the opened exact bilateral comparison identifies LDAC as a Liberty 4 NC advantage rather than a P40i advantage.[1, 3]
Soundcore by Anker Liberty 4 NC Wireless Earbuds
Soundcore lists Liberty 4 NC with 11mm drivers, Hi-Res Wireless, LDAC, HearID 2.0 and adjustable EQ.[2]
What this changes: Liberty 4 NC is the feature-fit choice for an LDAC-capable source and listener who will use that codec. Both offer app-based sound customization, so LDAC alone does not guarantee a better result with every phone or listener.[1, 2, 3]
Rated Battery And Fast Charge
Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
Soundcore rates P40i at up to 12 hours per charge and 60 hours with the case, with 10 minutes providing up to 5 hours of playback.[1]
Soundcore by Anker Liberty 4 NC Wireless Earbuds
Soundcore rates Liberty 4 NC at up to 10 hours per charge and 50 hours with the case; its product page lists 10 minutes for 4 hours.[2]
What this changes: P40i has the larger published battery and quick-charge figures. These are manufacturer ratings under stated conditions, not a bilateral runtime test or evidence of longer battery service life.[1, 2]
Water Resistance And Case Workflow
Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
Soundcore lists P40i as IPX5 and gives it a 2-in-1 charging case that doubles as a phone stand.[1]
Soundcore by Anker Liberty 4 NC Wireless Earbuds
Soundcore lists Liberty 4 NC as IPX4 and highlights its ANC, codec and multipoint features; its exact product page does not advertise a phone-stand case.[2]
What this changes: P40i is the feature-fit choice for greater documented water exposure protection or hands-free phone viewing from the case. This does not make it a waterproof product, and the IP ratings do not predict sound or ANC quality.[1, 2]
Best for your routine
Gaming and latency-sensitive video
Best fit: Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
RTINGS reports significantly lower P40i latency when Game Mode is enabled; the comparison does not provide a public numeric result, so confirm the behavior with the intended device and app.
LDAC-capable phone and high-bitrate wireless playback
Best fit: Soundcore by Anker Liberty 4 NC Wireless Earbuds
Based on listed features, not comparative testing.
Liberty 4 NC explicitly lists LDAC and Hi-Res Wireless. The source device and app must support LDAC, and using it can change available connection features.
Long sessions and quick top-ups
Best fit: Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
Based on listed features, not comparative testing.
P40i has the higher manufacturer-rated single-charge and case totals and the faster rated 10-minute top-up.
Rain-prone commuting or phone viewing from the case
Best fit: Soundcore P40i by Anker Noise Cancelling Earbuds with Adaptive ANC
Based on listed features, not comparative testing.
P40i lists IPX5 protection and a phone-stand charging case. It still requires ordinary care around water and charging contacts.
What the evidence cannot decide
- A proven universal ANC or call-quality winner: RTINGS describes overall performance as broadly similar with mostly minor differences, and the opened evidence does not establish a universal call-quality winner.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Liberty 4 NC's premium must be justified by LDAC and its feature fit for the buyer's phone and listening use. P40i is the stronger value fit when battery, Game Mode latency, water resistance or the phone-stand case matters more; refresh current offers before applying this rule.
The snapshot contains only a short observation window; there is not enough history for a definite Buy Now or Wait recommendation.
Is the upgrade worth it?
Worth considering if
- LDAC-capable phones and listeners who will use the codec
- buyers who prefer Liberty 4 NC's feature set and accept its shorter rated battery totals
Skip the upgrade if
- you need P40i's lower Game Mode latency
- you prioritize the longer rated battery, IPX5 protection or phone-stand case
- you expect a universal ANC, call-quality or reliability improvement
Limitations
- This is a source-based comparison; Pickoryx did not perform hands-on testing.
- Manufacturer battery ratings use stated test conditions and do not establish long-term battery durability or degradation.
- LDAC usefulness depends on the source device, app and connection settings; it is not a universal sound-quality guarantee.
- IPX ratings describe water-exposure protection, not waterproofing or safe use while charging.
- The exact Amazon records are black P40i A3955 B0CQXG17RL and black Liberty 4 NC A3947 B0BZV4QFP8; other colors or bundles may differ.
- No long-term reliability, fit, comfort or call-quality winner was established for this exact pair.
- RTINGS reports similar overall performance and a lower P40i Game Mode latency result, but the visible bilateral summary does not quantify the differences.
- No dependable long-window price history supports a definite Buy Now or Wait recommendation.
Questions shoppers ask
Is Liberty 4 NC an upgrade from P40i?
It is a targeted feature upgrade rather than a universal one. Liberty 4 NC adds LDAC and its Adaptive ANC 2.0 feature positioning, while P40i keeps the longer rated battery, lower Game Mode latency, IPX5 rating and phone-stand case. Upgrade only when the Liberty features change your routine.
Which has better noise cancellation?
The opened RTINGS comparison says the two perform similarly with mostly minor differences, so it does not support a universal ANC winner. Fit, ear tips, firmware and the listening environment still matter.
Which is better for gaming?
P40i is the evidence-backed fit because RTINGS reports significantly lower latency when its Game Mode is used. The public summary does not provide a numeric value, so test the intended game and device if timing is critical.
Does Liberty 4 NC have better sound because it supports LDAC?
LDAC gives Liberty 4 NC an option for higher-bitrate Bluetooth playback when the source device and app support it. It does not guarantee a better result for every listener, and P40i still offers app customization and a bass-focused feature set.
Which lasts longer?
P40i has the higher published battery figures: up to 12 hours per charge and 60 hours with the case, versus Liberty 4 NC's 10 and 50 hours. Those are manufacturer ratings rather than a long-term battery-life guarantee.
