The JBL Bar 300 is an all-in-one 5.0 soundbar with Dolby Atmos and JBL's MultiBeam technology, which beams sound sideways to widen the stage without rear speakers. PureVoice lifts dialogue clarity, and the JBL ONE app handles calibration and Wi-Fi setup. At 32.3 inches wide and 2.2 inches tall it fits under most TVs and suits renters or small rooms where a subwoofer and satellites are impractical. Against rivals like the Sonos Beam and Bose Smart Soundbar 600 it trades a dedicated subwoofer and true rear channels for a simpler single-box setup, so it widens sound but cannot produce the deep bass or surround placement of a full 5.1 system.

Owners generally like the wide, clear sound from a single bar and the easy setup through the app. Most criticism centers on bass that cannot match a system with a subwoofer and surround effects that stay in front of the listener.
