Soundcore Liberty 4 Pro 40h battery
Product description
What matters most
These earbuds combine advanced noise suppression with fast charging to bring calmer commutes and clearer calls. Liberty 4 Pro adapt noise cancellation every 0.3 seconds, so background roar fades and music stays detailed. The opening lines highlight adaptive ANC and quick recharge, making them useful for travelers and remote workers.
What you’ll notice day to day
You’ll hear fuller sound thanks to a 10.5mm bass driver and a titanium-coated tweeter paired with a digital crossover, delivering studio-level Hi-Fi music. Touch controls on the case let you tweak ANC levels on the fly, and AI-enhanced call processing with six mics keeps voices intelligible even in wind. Ten hours of playtime per charge and up to 40 hours with the case cuts downtime, but keep in mind actual runtime varies with volume and ANC settings.
