JBL Go 4 portable Bluetooth speaker
A small Bluetooth speaker for a desk, travel bag or casual listening away from home. Choose it when compact size matters more than filling a large gathering with sound. Use the JBL Portable app for supported settings and updates.

Battery life: what does the maximum mean?
JBL states up to 7 hours of playback, with up to 2 additional hours using Playtime Boost. The combined maximum is not the normal-mode battery rating. Runtime depends on volume, audio content and settings; these are manufacturer figures, not an Elechid battery test.
Check before buying
For stereo playback, confirm the exact two-speaker combination in the JBL instructions. Auracast multi-speaker connection should not be assumed to work with PartyBoost or Connect+ speakers. Check the required carrying accessories and charging equipment against the supplied package.
Water-resistance ratings apply under the manufacturer’s specified conditions. Keep the charging connector clean and fully dry before charging; do not interpret the rating as protection in every liquid or situation.
