JBL Soundbars BAR500MK2 and BAR300MK2 Get Major Upgrade for Ultimate Immersive Sound

JBL, a globally recognized audio brand known for delivering high-quality sound for both professional and personal use, has just announced a significant update for its popular soundbars, the BAR500MK2 and BAR300MK2. The new firmware, based on ONE OS 3.0, not only enhances the audio experience but also introduces support for DTS:X and various other DTS audio codecs.

For seven consecutive years, JBL has proudly held the title of the top-selling wireless speaker brand in Japan, according to sales data from various retail outlets. This new upgrade aims to further solidify JBL's position in the market by providing users with an even more immersive sound experience in their own homes.

The updated soundbars now support:

- DTS:X
- DTS-HD Master Audio
- DTS ES
- DTS 96/24
- DTS Virtual:X
