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.

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.

Sounds good, but not good for the gym or a run.

By BenCalifornia

from San Jose, CA

Comments about JBL Synchros On-The-Ear Headphones:

I bought this about 2 months ago. Luckily I haven't had the battery problems that other had. The sound is good. Unfortunately the earbuds fall out constantly. I've tried all three fittings included into with the earbuds, but all will fall out if I turn my head or after 5-6 steps when running. I wish they had fittings that would sit deeper into the ear canal. If you're looking for earbuds for the gym, I wouldn't recommend it. If you're looking for earbuds to wear at home then these work fine.

Great headphones when they work.

By Scooter2

from Vancouver, BC, Canada

Comments about JBL Synchros On-The-Ear Headphones:

Great headphones, they stay in your ears nicely. Sounds quality is good, HOWEVER - the bluetooth connection is very poor and cuts out sometimes. If I have my phone in my jeans pocket and I bend down or squat, the sound will cut out. The range in an open room seems to be fine, but certain angles/postures make it cut out. Checked and it's not the phone, definitely the headphones. Mystery to me.

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.
