Critic Reviews

JBL Bar 300MK2 review: powerful, bassy yet pleasingly subtle, it’s hard not to like this JBL soundbar | What Hi-Fi?

whathifi.com

The JBL Bar 300MK2 delivers a powerful, bass-heavy sound with a commendable Dolby Atmos effect, making it a solid alternative to the Sonos Beam Gen 2. Its impressive room-filling sound and clear dialogue make it a great choice for movie lovers. However, it falls short of the crispness and musicality found in top rivals, particularly in its handling of music playback. While the soundbar excels in delivering exciting, bass-rich audio, it can struggle with clarity in congested tracks. Overall, it's a robust mid-range option for those prioritizing cinematic sound over musical finesse.

JBL Bar 300MK2 review - Soundbar with new MultiBeam technology

stereoguide.com

The JBL Bar 300MK2 shines with its robust sound and impressive integration of streaming services through the JBL One app. While its Dolby Atmos capabilities don't quite elevate the soundstage, the soundbar delivers rich bass and a wide soundstage, ideal for both music and movies. However, it falls short with limited connectivity options, lacking subwoofer or rear speaker support. The bass also falters at higher volumes. Overall, this soundbar offers a compelling package for its price, especially for those in smaller spaces or seeking simplicity in setup.
