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.

Battery will no longer

By Eddyg

from Ashburn, VA, United States

Comments about JBL Synchros On-The-Ear Headphones:

I have had the earphones over a year. The earphones will no longer charge. I did not consistently use these earbuds. They sat in my drawer for many months but I used them daily for the past 2 months. What is the life expectancy? Changed charger, cable, outlet, etc. only red light shows and that does not last

Battery died

By trimet

from Carlsbad, CA, United States

Comments about JBL Synchros On-The-Ear Headphones:

I bought these about 4 months ago. Loved them and now the battery has died so they are trash. I gave them a 2 because I really liked them and maybe I was just unlucky .

Great sound, great customer service, POOR life.

By cindygirl

from Murrieta, CA, United States

Comments about JBL Synchros On-The-Ear Headphones:

I purchased my original pair in April of 2015 by August they had stopped working. Customer service was awesome and sent out a new pair. Then in March of 2016 they stopped working again and here I am a year later and they have stopped working. Always the same issue, the sound will start to go out on one side and then even though it has a full charge (indicated by the blue light) they will not power on. I use my headphones at most once a week and are in excellent shape-- sad that they can't seem to last more than a year.

Out the box won't turn on

By JakeNotFromStateFarm

from Aurora, IL, United States

Comments about JBL Synchros On-The-Ear Headphones:

Nice looking headphones they are fully charged and don't turn on so other than being completely inoperable they are great. I wish I could give less then one star on quality and durability.

Terrible

Comments about JBL Synchros On-The-Ear Headphones:

I have had three of these and they all did the same thing. After 2 or 3 months the the other can't hear you.

Not so much.

By Huhcanhearyou

from Savannah, GA, United States

Comments about JBL Synchros On-The-Ear Headphones:

I bought these to go along with my iPhone 7 for the blue tooth capability. The bass sucks as does the clarity of the speakers. I tried all three ear buds and several equalizing selections on a variety of music. Not happy. Oh, and the mic doesn't work very well either. My callers complain they can not hear me.

It's great until stop charging

By LEOSLARA85

from Rio de Janei

Comments about JBL Synchros On-The-Ear Headphones:

i've been searching for how to charging and the tutorial says it must turn leds on red (continuosly) but a tried many times to plug in and out, turn on and off, and still the leds off even with the cable plugged on the poewrpoint. Each time i decide to gpo running is a "unkonx" if i'm going to listen musci, or not... it's disappointing. I would give one to my father but i gave up.

Great Product

By EdwardR

from Belen, NM, United States

Comments about JBL Synchros On-The-Ear Headphones:

I have had them for a week now. The sound is excellent. They fit well. The battery has lasted well over 5 hour per charge. Time will tell as far as durability. I am very pleased with the purchase.

A little disappointing

By kwyman

from Cape Town, Western Cape, South Africa

Comments about JBL Synchros On-The-Ear Headphones:

Great sound, IF you can get the fit right so the noise cancelling feature works. Will not fall out...IF you manage to have one of three ear sizes EXACTLY (to fit the supplied fixtures) Glitchy Bluetooth connection (eventually skip free once I got an arm strap for my phone) Battery life was not bad at all, except the unit died at exactly one year and one month (out of warranty). Will not buy another JBL headset.
