| Feature | Needs |

| LDAC playback | Compatible Android 8.0 or later source. Enable Preferred Audio Quality in the soundcore app and install the required earbud firmware update. LDAC disables multipoint. |
| Full app features | Maker recommends soundcore app 3.2.7 or later and current earbud firmware. The companion app is not available for computers. |
| Computer calls | On Windows, select Liberty 4 NC Hands-Free for microphone and speaker in the call app. The maker Mac computer guidance instead says to select Liberty 4 NC for input and output. Stereo playback and hands-free calls use different Bluetooth audio modes. |
Source1Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Current maker FAQ states Android 8.0 minimum for LDAC, a firmware update to enable it, and mutually exclusive LDAC and multipoint. App 3.2.7 and later is the maker recommendation for full features, without asserting that this is the latest app version. Windows conferencing guidance specifically names the Hands-Free endpoint. The separate Mac computer guidance names Liberty 4 NC without that suffix. The visible requirement preserves both platform scopes.8Owner's manualsalesforce-knowledge-download.s3.us-west-2.amazonaws.com/000019752/en_US/000019752.pdfRead 8 October 2026LDAC section explicitly requires Android 8.0 or later and excludes two-device connection while LDAC is enabled. Additional regulatory and security sections are not treated as proof that old reviewed firmware is current.

Charging guidance
Less than 2 hours from empty. The maker does not separate earbud and case charging time.14Maker spec sheet (PDF)jbl.com/on/demandware.static/-/Sites-masterCatalog_Harman/default/dw4da7bc81/pdfs/JBL%20Vibe%20Beam_%20Specsheet_EN.pdfRead 8 October 2026The original Vibe Beam technical table on page 2 states charging time below two hours from empty. It does not identify whether that estimate covers earbuds, case, or both. The published guidance is retained without assigning it to earbuds-only or case-only full-charge fields. The maker webpage rounds the generic estimate to two hours.
The maker estimates about 1.5 hours for a full earbud charge in the case, about 3 hours for the case by cable, or 3.5 hours for the case wirelessly. Ten minutes of charging is claimed to provide four hours of earbud playback. The manual lists a 5 V / 0.8 A input. Use a certified USB-C charging cable and fully dry the buds and charging port first. ANC, LDAC, calls and volume affect runtime. LDAC and multipoint cannot be used together.2Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Component-specific full-charge times come from the current maker FAQ. The original manual table only says up to 3 hours without component scope, so that generic table alone does not establish earbud-only timing. Input 5 V / 0.8 A is literal. No accepted charging watts are derived. Current A3947C guide separately lists a compatible Anker A2337 30 W adapter, which is not a bundled adapter or device input rating.
Quick charge time
Earbud playback after quick charge
4h1Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Maker states 10 minutes for 4 hours.

ANC, codec and volume for this quick-charge claim are not stated, so they remain unknown.9Reviewrtings.com/headphones/reviews/anker/soundcore-liberty-4-nc-truly-wirelessRead 8 October 2026Public Office paragraph explicitly describes four hours of playback after ten minutes of charging in the case.
