Highlights

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 Synchro 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.

A unique LED lighting feature responds intuitively to every adjustment made to your headphones’ touch sensor control system, following the direction that you swipe your finger across the earcup.

Rated 5 out of 5 by from Great functionality! I bought this on Black Friday for a bargain. The touch screen is such a cool feature. I don't have to touch my phone at all to listen to my favorite music, but just need to press one button and the touch pad, both on the left ear. I sometimes plug into my computer at work which is a great option if I'm in my office for an extended amount of time. If I go for a walk, it's as simple as unplug, press two buttons and I'm listening to my favorite music in seconds. Also, very portable and comfortable with great sound quality.

Rated 5 out of 5 by from Great set of headphones Extremely crisp sound. Can play hard basslines and still play other sound without distortion. Wireless feature is amazing, really is convenient if you don't want to have your phone out while you listen.

Rated 5 out of 5 by from Best to date The S400BT is by far the best pair of Bluetooth headphones I've owned to date. Intuitive, easy to use, pair, looks awesome, & sounds way way better than Beats headphones (but that is just my personal opinion). Unlike most "on-the-ear" headphones these sit super lightly on your ears & do not squeeze your head over the length of time that you wear them which is great! The touch sensor is a BALLER feature!!! I love the simplicity behind the design of these headphones. I also know from experience that if you compare the performance these are better than the S500. If there was one thing I can change is that they were over-the-ear headphones. Lastly, if you want to talk about price range for what the end product is worth, I would have happily paid another $60 if JBL asked for it. And if you are contemplating on buying these or not.....please stop wasting your time and buy these already. Don't wait, just buy & buy now. And JBL customer service is second to none. I'm a super happy satisfied customer.

Rated 5 out of 5 by from Absolutely Amazing Bought this last week, couldn't be more happy with them. The swipe feature and LED patterns get so much attention its ridiculous. They noise cancelling on these headphones is phenomenal. They sound better than my friends $400 Bose nosie canceling over-ears.

What is the difference between S400 BT and S400 BT+ ? Any difference in the sound specs? Surprised there's no mention on your corp site for the +. ....

Asked by: rchilde
The S400BT+ is not a product that we sell in the US. If you are located outside the US you would need to get in touch with the dealer who carries the S400BT+.

why is the sound is low right side of my jbl synchros s400bt ?

Asked by: Smashing
Its possible that you do not have the 3.5 jack plugged in all the way or properly. If the jack is not fully connected and inserted, it can cause the sound to drop or be muffled. If you are still experiencing issues with the sound, please contact your local JBL Customer Service for technical support.

What is the proper way to charge these?

Asked by: Jb8301
The Synchros S400BT comes with a micro USB cable that you can plug into your laptop or computer. The 2.5 mm jack end will need to be plugged in on the right ear phone that is located between the power and the bluetooth button.

What is the actual range of bluetooth? I sat 10 feet away from TV and sound jittered. It works perfectly fine when I sit in 6 feet range of TV.

Asked by: Athar
The S400 typically has a 30-40 ft bluetooth range. Try using the headphones on another device to see if you still have the same distortion after 10ft. If the problem persists, please contact your local JBL Customer Service for technical support.

Good morning!  Hey, can you tell me about the sale of these at Sprint?  They have them for $99.00 (huh?).  Anyway, I buy direct from you -- I'm just not certain that I will this time because of the extreme price difference.    Thanks.  

Asked by: Lorre
At this time we do not have any information regrading the sale that your local Sprint store is having. But they are one of our authorized retailers and we will still honor the 1 year warranty if you decide to purchase our product directly from Sprint.
