You cant press pause on a pro-audio revolution certainly not when JBL engineers are at the helm. Introducing the new JBL S400BT Synchros Bluetooth 3.0 Wireless On-The-Ear Black Headphones. As the latest addition to the JBL Synchros line of premium headphones, the award-winning S400BT adds the freedom of Bluetooth 3.0 wireless to the performance of a Synchros headphone. Using advanced aptX digital encoding technology that streams high-resolution audio on par with any wired Synchro headphone, the S400BT is fine-tuned on the inside to maximize enjoyment on the outside.

Now you can showcase your listening experience at the speed of light. Viewed as a whole, the S400BT is a wireless headphone that's meant to celebrate - as much as to simplify premium listening. Chances are you've never witnessed a headphone that comes even close to this.
