JBL has introduced Synchros, a new line of headphones. The flagship headphones in the line are the Synchros S700 ($350) premium powered over-ear stereo headphones. Made out of aluminum, fabric, and steel, with leather ear cushions, the onyx- or glacier-colored S700 headphones use 50mm drivers, JBL LiveStage signal processing technology, and a rechargeable battery that lasts for 28 hours. The Synchros S500 ($300) are similar, but use AAA batteries instead of a Li-on battery, and the materials aren’t quite as high-end.

Also introduced were the Synchros S300 ($200), on-ear headphones that feature 40mm drivers and are available in six colors. The Synchros S200 ($130) are in-ear stereo headphones with a 10mm drivers, while the S100 ($100) headphones are very similar, with a 9mm driver instead. The entire line is available now.
