The Soundcore Liberty 4 Pro packs 7-sensor ANC, genuinely good LDAC sound, and a touchscreen case that turns out more useful than it looks -- all for well under flagship money. Lab-tested battery life falls short of the 7.5-hour ANC claim, and the case is chunky. Check the live Amazon price: at discounts, it's the value pick of the category.
— THE VERDICT · JUDGEANY EDITORSWhat the Liberty 4 Pro is
The Liberty 4 Pro is Anker's late-2024 flagship earbud, and the case is the headline act: a small display and a touch bar show the battery level of each bud and the case itself, and let you adjust noise cancelling without opening the Soundcore app. The buds use a stemmed design and carry a 10.5mm bass driver plus a 4.6mm titanium-coated tweeter per side on Soundcore's ACAA architecture, with a digital crossover splitting frequencies between them. Bluetooth 5.3 covers SBC, AAC, and LDAC, and multipoint is included. The buds are IPX5 against water, and six ear tip sizes (XXS to XL) come in the box. Finishes are glossy black, white, and glossy light blue -- the white case is matte, so it hides the display when closed while the glossy ones show it through the lid.
The smart case, evaluated
The display shows each bud's charge, the case's charge, and the active sound mode -- ANC, transparency, or normal. Swipe the touch bar to dial ANC intensity up or down or to switch spatial audio on; double-tap confirms a choice. SoundGuys calls the case display somewhat of a gimmick, and that rings true: it is genuinely useful at a desk when your phone is in another room, and mostly forgotten once you are deep in the app. The trade-off is a bigger-than-average case, and Root-Nation reports stray swipes on the bar changing the ambient-sound level by accident.
What published tests found
SoundGuys gives the Liberty 4 Pro 8.2 out of 10, and its lab prediction says most listeners will like the sound (MDAQS overall 4.8 out of 5). The 7-sensor adaptive ANC recalibrates every 0.3 seconds and cut roughly 30dB in lab testing -- strong, though SoundGuys notes Sony and Apple flagships still pull ahead on low-frequency rumble. Battery is the weak spot on paper: SoundGuys measured 5 hours 42 minutes with ANC on against the 7.5-hour claim, and truthful.reviews got 6 hours 45 minutes at 50% volume. A 5-minute charge restores about 4 hours of playtime, which both sources confirm. The six-mic array handled simulated wind and reverb well in SoundGuys' tests. Reviews agree the default tuning is energetic -- punchy bass and mids, with highs that Android Central found bright enough to fatigue at volume. The Soundcore app is a highlight: an 8-band custom EQ, 22 presets, and a personalized HearID profile. Recurring knocks: underwhelming spatial audio, an Easy Chat auto-ducking feature that fires by mistake, and bud touch controls that PC Gamer kept triggering while inserting the buds. We run no lab; scores below are editorial judgments on this published evidence.
Who should buy it
Buy the Liberty 4 Pro if you want flagship-adjacent features -- LDAC, strong ANC, multipoint, wireless charging -- for well under flagship money. Digital Trends calls value "the best thing about the Liberty 4 Pro." Skip it if top-tier low-frequency ANC is the priority -- Sony's WF series and AirPods Pro lead there -- or if you expect spatial audio that actually impresses. On a tighter budget, Digital Trends points at the cheaper Liberty 4 NC or the Earfun Air Pro 4. Check the live price on Amazon before deciding; Anker discounts these regularly.
