Soundcore Liberty 4 Pro True Wireless Earbuds – Glossy Light Blue
The Soundcore Liberty 4 Pro are true wireless noise-cancelling earbuds built for commuters, remote workers, and music listeners who want a feature-rich experience without paying flagship prices. They combine a dual-driver acoustic system with a 7-sensor adaptive noise cancellation engine, a 40-hour total battery reserve, and a translucent smart charging case that displays battery percentages at a glance. The Glossy Light Blue colourway adds a semi-transparent lid that lets the internal case display show through — a practical visual flourish with real function.
Codec compatibility note: LDAC high-resolution audio streaming is available on Android devices only. iPhone users connect via AAC and SBC. If LDAC support matters to you, verify your phone’s codec compatibility before purchasing.
ANC and call use reduce battery life: Earbuds last up to 10 hours without ANC. With ANC enabled, expect approximately 7.5 hours per charge. Continuous voice calls draw more power than audio playback — plan charging accordingly for full-day meeting schedules.

Use Cases
Daily Commuting and Travel
The 7-sensor ANC engine handles repetitive low-frequency noise — engine rumble, rail hum, aircraft cabin pressure — without requiring manual adjustment. The barometric sensor means the ANC recalibrates as the aircraft cabin pressurises, so it stays effective from boarding to landing. Multipoint connection keeps your work phone and personal phone paired simultaneously, so switching between them happens automatically.
Remote Work and Video Calls
Six microphones with AI noise suppression keep your voice clear whether you’re working near a window on a windy day or in a busy café. The EasyChat function removes the need to pause music manually every time a colleague walks over — it detects when you begin speaking and lowers the music. For back-to-back video calls, 7.5 hours of ANC-on battery covers a full working day on a single charge.
Hi-Res and Critical Listening
Android users who stream via Tidal, Qobuz, or Amazon Music HD unlock LDAC playback at up to 24-bit/96kHz. The dual-driver system separates bass from mid and high frequencies with a digital crossover — so low-end impact does not compromise vocal clarity. The HearID 2.0 calibration test tailors the EQ curve to your specific hearing response, which makes a noticeable difference for listeners who find factory EQ tunings too heavy in the bass.
Fitness and Outdoor Use
At 5.5g per earbud, the Liberty 4 Pro sits lightly during workouts. IPX5 water resistance protects against heavy sweat and light rain — however, submersion is not rated, so avoid use while swimming. Six ear tip sizes allow precise canal sealing, which improves both passive isolation and ANC effectiveness during exercise when head movement can otherwise break the seal.
Considerations
- LDAC on Android only. iPhone users receive AAC, which is solid for everyday listening but does not unlock the full 24-bit/96kHz resolution stream. If high-resolution wireless audio is your primary purchase driver and you use an iPhone, consider this before buying.
- Spatial Audio implementation. Head tracking and 360° spatial audio are available and genuinely functional for film and gaming content. However, independent tests note that spatial audio primarily reduces volume rather than adding significant three-dimensional detail. It is a useful bonus feature, not the core reason to buy these earbuds.
- Case fingerprint visibility. The glossy, reflective lid of the Glossy Light Blue case attracts fingerprints readily. This is cosmetic and does not affect performance, but it is worth knowing if surface appearance matters.
- Gaming codec. There is no dedicated low-latency gaming mode. However, real-world testing shows acceptable synchronisation for casual mobile gaming. For precision competitive gaming, a wired connection to a controller or device is preferable.
- Case controls require the case to be open for some functions. Adjusting ANC strength via the touch bar works with the lid closed. However, selecting spatial audio modes and most other case menu options require you to open the lid for the display to be fully interactive.
Frequently Asked Questions
Does the Liberty 4 Pro work with iPhones? Yes. The earbuds pair over Bluetooth 5.3 and work with all iPhones. However, LDAC high-resolution audio is only available on compatible Android devices. iPhone users connect via AAC.
Can I use one earbud at a time? Yes. Single earbud use is supported in single mode. Place the other earbud in the charging case while using only one side.
Is the charging case waterproof? No. The IPX5 water resistance rating applies to the earbuds only, not the charging case. Keep the case away from water.
How many ear tip sizes come in the box? Six pairs — XS, S, M, M+, L, and XL. This range accommodates most ear canal sizes, including users who find that standard three-size sets do not fit comfortably.
Does wireless charging require a specific charger? No. Any Qi-compatible wireless charging pad works. However, a Qi charger is not included in the box — only the USB-C cable is provided.
What does EasyChat do? EasyChat detects when you start speaking and automatically lowers music volume while switching to transparency mode, so you can have a brief conversation without removing your earbuds or pausing playback manually. It deactivates when you stop speaking.
Does the case display work through the closed lid? For the Glossy Light Blue variant, yes — the translucent lid allows the internal LCD screen to be visible from outside the closed case. You can check battery percentages and swipe the touch bar without opening the lid.
