JBL's 2025 compact 5.0-channel all-in-one Dolby Atmos soundbar adds MultiBeam 3.0 and PureVoice 2.0 to the popular Bar 300 chassis. The rear panel has one HDMI input alongside an HDMI eARC output to the TV, plus an optical TOSLINK fallback and a USB-A port. HDMI passthrough is 4K with HDR10+ and Dolby Vision but does not support 4K@120Hz, so console gaming above 60Hz should connect directly to the TV. There is no separate subwoofer — bass comes from the bar itself, with optional wireless surrounds available.
