JBL
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. Take the headphones hassle-free single touch sensor for instance: all you need to do is swipe your finger anywhere along the S400BTs left outer earcup, and you can seamlessly adjust your headphones 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, its 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 headphones 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.

Bad for Cycling

By Trudeau

from Undisclosed

Comments about JBL Synchros On-The-Ear Headphones:

I bought these specifically for cycling but when riding with my phone in my backpocket on my jersey the sound cuts out constantly i'm not sure if the signal is being effected by speed? i can easily travel 30 to 60 KM/hr on my road bike. They work fine while i'm in the gym however. i can be across the room and they work.

On/off

By Suckfish1969

Comments about JBL Synchros On-The-Ear Headphones:

I was just wondering...when the device you are using to pair the buds with is off....does that mean the buds are off also? If not; is there a power off switch for them!? Otherwise..super product by JBL!

Garbage

By Bennijiggs

from New Mexico, United States

Comments about JBL Synchros On-The-Ear Headphones:

Works and sounds great if you duct tape your phone to your head. Bluetooth range is horrible. In your pocket off and on connection, take out works ok. My Bose will work from anywhere in the house. Garbage. Save your self the hassle.

Bought a little over a year ago, battery no longer holds a charge. Cannot justify replacing every year, will no longer purchase JBL products.

No durability

By TyroneL

from Melbourne, Victoria, Australia

Comments about JBL Synchros On-The-Ear Headphones:

Great sound quality and stays in locked in the ear. However after 2 months of use the headphones suddenly don't hold any charge and turned off after 20 minutes of full charged use and will not power on again. The cone inside the right speaker had issues. The Play/Stop button suddenly always regsitered as you pressed twice fast and pressing the button twice too fast will not skip track. The volume up/down also stopped working around the same time as the Play/Stop button stopped working. I was happy with the first pair and hoped that I was just unlucky and received a faulty one. However the exact same issues occurred in the SECOND replacement pair. Disappointed as the audio quality was the best for that price.

worst headphones ever...good customer service

By jamie1983

from Georgia, United States

Comments about JBL Synchros On-The-Ear Headphones:

I have had to have these headphones replaced 3x now in 6 months. When they work, they are great, very comfortable, and good sound. However the reliability is terrible. I got my replacement set about 3 weeks ago, and they are already broken. I purchased a set for my wife and they stopped working within a month. The plus side is their customer service, they have been quick to replace without issue.

Comments about JBL Synchros On-The-Ear Headphones:

Got these with my new phone. Excellent quality. Pretty comfortable, except after a few hours of use, but its usually not a big deal.
