Renowned industrial designer Yves Behar has been the force behind the look of Jawbone since it first launched in 2006. With its clean lines and invisible buttons, the first Jawbone pioneered a headset look that shook off all robotic science-fiction clichés. The newest version, which arrives at Barneys next week in either rose gold or matte black finishes, goes one better: It features all the latest tech updates, while being 50 percent smaller and extremely lightweight. Jawbone, $130, available at Barneys New York, (212) 826 8900.
