Bringing "live" sound to your headphones

In addition to their consumer audio pedigree, JBL has been a leader in live sound for decades. When they designed their Synchros S700 headphones, they wanted to deliver as much of that "in the club" listening experience as possible. They developed LiveStage™ digital signal processing to offer a unique headphone experience. LiveStage moves the soundstage forward to simulate a concert or speaker-listening experience. Powered by a rechargeable battery, the Synchros S700 headphones deliver up to 28 hours of LiveStage-activated listening with a single charge using the included USB cable. What happens if your battery runs down? You keep listening. The passive listening option means your music will still sound rich and detailed even without LiveStage processing.

Remote cables for Apple® and Android™

If you have an iPhone® or other Apple device, you're probably used to seeing headphones with in-line remotes and microphones that work with these products. The Synchros S700 is no exception. But JBL didn't leave Android users out of the mix. These headphones come with a second remote cable for use with compatible Android devices. Both cables allow you to take calls with a smartphone as well as control playback and volume when listening to music. The miniplug connection in the left earcup makes it easy to swap out one for the other.

High-quality construction

The Synchros S700s will attract attention with their pro-style looks. But these headphones go beyond mere fashion. With an aluminum frame, sturdy headband, and leather earpads, these 'phones are built to last. They also offer enough comfort to keep you listening, whether you're working on a home recording project or just kicking back enjoying your favorite tunes. With JBL's pedigree for both live sound and home audio, these headphones are great for the studio or the living room.

Features

Overview: The JBL Synchros 700 over-ear headphones are designed for comfort and great sound. The Synchros 700s feature precision-crafted die-cast aluminum frames, woven cordura accents, padded steel headband, and leather ear cushions. The drivers are based on the famous JBL professional audio systems to deliver powerful bass and pristine highs. The addition of the proprietary LiveStage powered signal processing gives you a more realistic sound. The Synchros 700 headphones come with two interchangeable cables, each with a 3-button mic/remote, a USB charging cable, and a soft padded storage case.

Drivers: The Synchros 700 features large 50mm drivers that delivers powerful audio with clear highs and original JBL PureBass performance.

LiveStage: JBL's proprietary LiveStage is a switchable signal processing circuit that gives you the purest listening experience. It creates a sense of spatial presence that makes you think you are listening to a pair of loudspeakers in a room. LiveStage is powered by a rechargeable Lithium-ion battery, and can be turned on or off by pressing the JBL logo on the left earcup. The battery can be charged in approximately 2-1/2 hours using the supplied USB charging cable. A fully-charged battery will provide approximately 28 hours of audio when using LiveStage.

In-line Mic/Remotes: The Synchros 700 comes with two 50" straight cables, each with a 3.5mm miniplug terminal and a 3-button in-line remote/microphone. One cable is compatible with Apple iOS devices, while the other "universal" cable works with Android and most other smart devices:

  • Made for iPod/iPhone/iPad: The Synchros 700's controls are certified compatible with iPod, iPhone, and iPad. They work with iPhone (3GS or later), all iPad models, iPod touch (2nd gen or later), iPod nano (4th gen or later), and iPod classic (120GB/160GB). The iOS-compatible cable has terminals with white bands.
  • Universal Cable: The "universal" cable works with many popular smartphones, feature phones, and tablets, including Samsung, Sony Xperia, Nokia Lumia, HTC, LG, Blackberry, Google, Android, and Windows devices. Functions vary depending upon your phone, tablet, or application. The "universal" cable has terminals with black bands.

Storage Case: The padded zippered clam-shell case has a soft lining to protect your headphones from bumps, and lets you store your headphones for easy transport. An elastic pocket in the inner lid is for storing your spare cables and other accessories.

SO GOOD

have been through BOSE over ear noise cancellation and Beats by Dre. Both give a buzz when connected to iPhone or Macbook . so i went with cans that don't have official 'noise cancellation' . these S700s BLOW AWAY both the Bose and Beats. I put my Beats on yesterday because i left my JBLs at home and the Beats experience was FLAT . just horrible, in comparison to these S700s. Note though, the LiveStage DSP function is worthless - makes a lot of tracks sound 'tinny', but in standard mode these phones are incredible. GREAT mid-range and deep bass, without sacrificing mid and highs. very happy ...
