Soundcore Liberty 4 NC Pink

Soundcore Liberty 4 NC (Pastel Pink) — Adaptive ANC Earbuds with LDAC and Wireless Charging

The Soundcore Liberty 4 NC Pastel Pink are true wireless noise-cancelling earbuds built for commuters, remote workers, and everyday listeners who want reliable ANC without paying flagship prices. They combine Adaptive ANC 2.0, LDAC Hi-Res wireless audio, and Qi wireless charging on the case — a combination rarely found below the £100 / $100 price point. Furthermore, with up to 50 hours of total battery life and a 10-minute fast charge option, the Liberty 4 NC handles full working weeks between top-ups.

⚠ LDAC is Android-only. LDAC requires Android 8.0 or later. It is unavailable on iPhones and iPads. iOS users connect via AAC or SBC instead — which still delivers good audio quality, but without Hi-Res wireless capability.

⚠ LDAC and multipoint connectivity are mutually exclusive. You can use both features, but not simultaneously. Enabling LDAC on your primary device automatically suspends multipoint; switching to multipoint disables LDAC. Choose whichever matters more for a given listening session.

⚠ No wall charger included. The box contains a USB-C cable and the wireless charging case. A separate USB power adapter or compatible wireless charger pad is required.

Use Cases

Commuting and public transport

Adaptive ANC 2.0’s transport-specific modes are particularly practical here. For instance, the Bus mode targets the low-frequency rumble of a diesel engine, while Train mode addresses the higher-pitched track noise that fixed ANC curves tend to handle less effectively. IPX4 water resistance additionally covers light rain during outdoor segments of a commute.

Focused work in open-plan environments

The five-level ANC adjustment means you can dial back cancellation incrementally — enough to reduce distracting chatter without fully isolating yourself from the office. Meanwhile, Transparency mode allows you to hear a colleague without removing the earbuds. The 50-hour total battery is particularly practical for those who routinely forget to charge accessories over the weekend.

Travel — international and domestic flights

Airplane Mode applies stronger, lower-frequency cancellation tuned specifically for jet engine drone. Because the Liberty 4 NC case supports Qi wireless charging, you can top it up on an airline or hotel wireless pad without carrying an additional cable. As a result, long-haul travel becomes considerably simpler to manage from a power perspective.

Casual listening and music discovery

HearID 2.0’s personalised EQ profile ensures that even at moderate volumes, the frequency balance suits your specific hearing sensitivity. Furthermore, the 22 genre presets provide a quick route to a well-tuned starting point before you apply manual adjustments. The 11mm driver’s bass output makes the Liberty 4 NC particularly well-matched to genres such as R&B, hip-hop, and electronic music.

Calls and remote meetings

Six beamforming microphones arranged across both earbuds capture your voice from multiple angles simultaneously. As a result, background noise — keyboard clicks, street sound, air conditioning — is filtered out more reliably than with a single or dual-mic arrangement. The auto-answer on wear feature additionally speeds up answering incoming calls without reaching for your phone.

Considerations Before Buying

iOS users do not get LDAC. Apple’s Bluetooth implementation does not support the LDAC codec regardless of device model or iOS version. On an iPhone or iPad, the Liberty 4 NC connects via AAC, which still sounds good — however, the Hi-Res wireless capability is unavailable to iOS users.

LDAC and multipoint do not run simultaneously. If you regularly switch audio between a laptop and a phone, you will need to choose between multipoint convenience and LDAC audio quality on any given session. This is a firmware-level constraint, not a setting error.

IPX4 covers splashes but not submersion. The rating handles sweat, light rain, and the occasional accidental spill reliably. However, it does not cover swimming or sustained water exposure. For aquatic exercise, an IPX7 or IPX8 rating would be required.

Pastel Pink is a light-coloured finish. Light colourways tend to show surface scuffs and everyday marks more readily than darker variants such as Velvet Black. If you carry the case loose in a bag alongside keys or coins, a protective pouch is worth considering.

Four ear tip sizes only. Unlike the Liberty 5 (which includes six sizes), the Liberty 4 NC ships with XS, S, M, and L. Most users will find a comfortable seal within those four options — though if you have an unusual ear canal size, the Liberty 5’s broader range may be a better fit.

Frequently Asked Questions

Can I use the Soundcore Liberty 4 NC Pastel Pink with an iPhone?

Yes, but with one significant limitation. The earbuds pair with iOS devices via Bluetooth 5.3 using SBC or AAC. All other features — Adaptive ANC, HearID 2.0, multipoint, Transparency mode, gaming mode, wear detection, and the Soundcore app — work normally on iPhone and iPad. However, LDAC requires Android 8.0 or later and does not function on any Apple device.

Does the Liberty 4 NC support multipoint connection?

Yes. The earbuds connect to two Bluetooth devices simultaneously by default, allowing you to switch audio between a laptop and a phone without re-pairing. However, multipoint and LDAC cannot be active at the same time. If LDAC is enabled on one device, multipoint is suspended until LDAC is turned off.

How does the Pastel Pink colourway differ from other Liberty 4 NC variants?

Hardware-wise, there is no difference. The Soundcore Liberty 4 NC Pastel Pink (A3947Z51) shares identical drivers, ANC system, battery capacity, Bluetooth version, codecs, and firmware with the Velvet Black (A3947Z11), Navy Blue (A3947Z31), and Clear White (A3947Z21) colourways. Only the colour finish differs.

What is the difference between ANC levels and transport modes?

ANC levels (1–5) adjust the overall intensity of noise cancellation from light to maximum. Transport modes, in contrast, optimise the frequency profile for a specific noise environment — Airplane mode prioritises low-frequency engine noise, while Train mode targets higher-pitched wheel and track frequencies. You can combine a transport mode with a specific ANC level for further fine-tuning via the Soundcore app.

Is the charging case really compatible with any Qi wireless charger?

Yes. The Liberty 4 NC charging case supports standard Qi wireless charging and is compatible with any certified Qi pad — including multi-device pads, MagSafe-compatible pads (non-magnetic alignment), and in-car wireless chargers. Charging time via a Qi pad is longer than via USB-C cable, so overnight charging is the practical approach for wireless topping up.

How does HearID 2.0 differ from HearID 4.0 on the Liberty 5?

HearID 2.0 on the Liberty 4 NC analyses your hearing sensitivity across a range of frequencies and generates a personalised EQ curve accordingly. HearID 4.0 on the Liberty 5 additionally factors in your age group and music listening preferences — producing a profile that accounts for both audiological variation and genre-specific taste. As a result, the Liberty 5’s personalisation is more comprehensive, though HearID 2.0 still provides a meaningful improvement over a generic factory EQ setting.
