The S400BT: a new experience in sound and simplicity

The portable revolution will be synchronized. You can’t press pause on a pro-audio revolution – certainly not when JBL engineers are at the helm. Introducing the new JBL S400BT. 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 Synchros headphone, the S400BT is fine-tuned on the inside to maximize enjoyment on the outside. Take the headphone’s hassle-free single touch sensor for instance: all you need to do is swipe your finger anywhere along the S400BT’s left outer earcup, and you can seamlessly adjust your headphone’s volume, track-changes, and call settings, since the entire earcup functions as a single, touch-sensitive control system. The right outer earcup boosts user flexibility as well, coming with an NFC sensor that pairs your headphone to any NFC-enabled device. Just give the right earcup a single tap, and you’re instantly connected. With this level of intuitive technology at play, it’s hard not to notice how the S400BT simplifies like never before. Others will definitely take notice: a built-in LED lighting system trails the touch of your hand in reaction to each adjustment made to your headphone’s settings. 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.

Sound modeled after industry leading JBL professional audio speakers delivers a balanced audio experience with amazing clarity and deep powerful bass, while advanced aptX encoding lets you experience the highest possible wireless sound quality available.
Wireless technology liberates you from the hassles of wires, while NFC technology on the right outer earcup simplifies the Bluetooth pairing process. The innovative touch sensor controls on the left earcup enable you to advance tracks, adjust volume, and play or pause your music, as well as take your calls – all with an easy swipe of your finger anywhere along the earcup’s surface.
To every adjustment made to your headphones’ touch sensor control system, following the direction that you swipe your finger across the earcup.
