JBL Synchros S400BT Quick Start Manual - Synchros S400Bt

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.
