Precision designed die-cast aluminum frame with woven accents, steel headband and soft leather ear cushions

In a world grown oversaturated by conventional, plastic headphones, we decided to take a long, bold leap into authenticity. Imagine a lightweight yet durable die-cast aluminum frame with a sturdy steel headband. Picture woven fabric accents. Think sculpted, soft leather ear cushions that envelop your senses in precision-designed comfort. In sum, envision the new S700 Stereo Headphone by JBL. Born from groundbreaking acoustic research in Harman's laboratories, the S700 is modeled after the same JBL sound systems used in the world's most prestigious clubs, delivering a balanced audio experience with razor-edge clarity and deep, powerful bass.

Proprietary LiveStage™ DSP gives listeners a more lifelike audio experience

From the company that gave you some of the world’s finest concert and club sound systems comes a headphone that carries all the power and precision of a live concert event straight into your ear. That’s the concept behind JBL’s proprietary LiveStage™ digital signal processing technology – as easy to use as it’s impossible to imitate. With the simple push of a button on your earcup, you’ll find yourself front and center – engulfed in a lifelike music experience without precedent. How it Works; LiveStage represents a breakthrough in acoustic research. Using an advanced, binaural digital signal processing, LiveStage recreates the sense of spatial presence that you feel when listening to loudspeakers in a room, creating immense sound dispersion, unadulterated vocals, and stunning instrumentals. A true listening pleasure,

JBL Professional Audio Sound with PureBass performance

It’s no trade secret we’ve created the world’s most legendary loudspeakers. Artists from the Beatles to Maroon 5 have used JBL equipment to create some of their most historic recordings. So it should come as no surprise we’ve taken Pro-Audio sound to new highs – and depths – of power and portability in our Synchros Series. Introducing JBL Professional Audio Sound with PureBass performance. To recreate the first ever Pro Audio experience in headphones, we first had to define it: enter JBL LSR 6332 loudspeakers. Harmonious, complex and truly lifelike, we sought to recreate the awe-inspiring listening experience within the Synchros series of headphones. JBL engineers painstakingly measured the LSR 6332 acoustic profile, and leveraging decades of audio engineering expertise, translated it to a unique headphone listening experience – ready for the most diverse and demanding of playlists. PureBass performance is much more than a tag-line, it’s a philosophy. Focusing on the full audio spectrum, not just the low end, the headphones deliver a balanced audio experience with amazing clarity, and deep powerful bass; producing clear separation of notes, avoiding the boominess and muddy sound found in other popular headphones.

Built-in, rechargeable Li-ion battery powers a full 28 hours of enhanced listening with LiveStage technology

One key thing almost every other powered headphone lacks is the power to sound good even when the battery power runs out. The S700 features a built-in, rechargeable Li-ion battery to deliver 28 hours of enhanced listening with LiveStage technology, but it also features a Passive playback mode to keep the music going even when the battery is dead. Unlike other powered headphones, the S700 is designed to sound great in passive mode, so even though the benefit of LiveStage technology is inactive without power, your music will still come through loud and clear.

Compatible with your choice of either iOS or Android devices.

Detachable cable design with both an iOS 3-button remote/microphone cable and a universal 3-button remote/microphone cable included, giving you the flexibility you need for on-the-go listening.

Synchros S700 is rated 4.5714 out of 5 by 14.
Rated 5 out of 5 by from Just delightful. The in-line control is kind of goofy, but these headphones sound amazing. I say goofy because double clicking is supposed to skip forward, but it's not very reliable. You have to double click at just the right speed for it to work. But maybe this is due to the device I'm plugged into... Not sure, so I gave 5 stars anyway.

Rated 4 out of 5 by from Awesome! I ordered these a few weeks ago to work out. They are the best headphones I've ever purchased. I had purchased the Bose Bluetooth headphones but returned them a week before because they gave me a headache and I'm glad i did. The ONLY reason these aren't getting a 5 star is because when i lay down on a bench or look up the headphones seem to want to slide off. Which can throw my workout off because i have to sit there and adjust it. Other than that, best I've ever had. I hope they last for years !

Rated 5 out of 5 by from Nothing compares to this! I'm a former musician with live performance and studio recording experience. There are no better headphones than JBL Synchros S700. I've tried them all. I admire JBL for such high quality standards.

Rated 2 out of 5 by from Decent cans for the price....BUT I have a very selective set of ears which demand very high quality sound. I have demoed many sets of cans over the years and would put these in my top 3. They are better sound quality and bass than the Beats by Dre and Bose over ear sets... I find the build quality to be average and thin plastic in critical tension points. They are uncomfortable after 30-40 minutes of use, and the cable quality is thin and low gauge for the price IMHO. I purchased a pair of Velodyne VTrue over ear studio headphones about 2 years ago and have yet to find anything even close to their crisp sound quality, booming bass reproduction, and far superior build quality and quality of materials. The full leather cups and headliner offer the ultimate in comfort for hours of long use. If your in the market for top quality headphones, the JBL should be your second choice... Get the Velodyne, you won't regret it.

Rated 4 out of 5 by from Questionable I bought my pair of Synchros S700's October 2013, The sound reproduction that JBL is known for is excellent, but the build quality is questionable.
