JBL Synchros S700 Details
The genuine Synchros S700 was a flagship model in its line, known for a high-quality audio experience, durable construction, and a unique sound-processing feature.
- Design & Build: It features a precision-crafted design using lightweight die-cast aluminum, a steel headband, and soft leather earcushions.
- Audio Drivers: It uses large 50mm dynamic drivers to deliver clear, powerful audio with PureBass performance.
- Connectivity: It is a wired headphone that comes with two detachable cables (one for iOS and one for Android devices), each with an in-line remote and microphone.
- LiveStage Technology: A key feature is the rechargeable battery-powered (up to 28 hours) LiveStage™ digital signal processing (DSP) which widens the soundstage to simulate a live concert or speaker-listening experience.
- Passive Mode: It can still be used in passive mode (without battery power/LiveStage engaged) if the battery dies, unlike some other powered headphones.
The “JBL S-700” as a simple, general name often refers to generic, non-authentic models that may not have any of these features.
