BRAVEN 850 & 855s utilise class-leading extended-range aluminum cone drivers and dual passive radiators for powerful sound for a portable speaker.
The new Braven's also have an integrated speakerphone to make calls, digitally enhanced audio based on DTS Audio's SRS WOW technology that expands sound.
Both 850 and 855 has 20 watts speaker power, playtime of up to 20 hours but the 855 has a water resistant shell, and IXP3 water-resistant rating.
Both models cost A$399, and measure less than 25cm and 11cm tall.
The wireless speakers doubles as a charger for mobile devices.
"The 850 & 855s take BRAVEN's family of award-winning portable speakers to new decibels and encourage users to enjoy life to the fullest and loudest - in stunning high fidelity audio," stated Valentine Lopez, Executive Vice President.
"Despite their portability, the 8 series speakers have the features and capabilities to satisfy even the most demanding music connoisseur. They are simply a step above the rest."
