AlphaTheta HDJ-F9 Professional Wireless DJ Headphones

The HDJ-F9 DJ headphones deliver precise monitoring with powerful low frequencies and balanced mids and highs, even in loud DJ booths. Featuring SonicLink connectivity, a flexible swivel design and durable die-cast aluminium construction, they’re built for comfort and reliability. A secure bayonet locking cable connection helps prevent accidental disconnection, while the HEADPHONES CONNECT app makes it easy to locate misplaced headphones using the built-in Find My Headphones feature.

• SonicLink Connectivity - Simply touch your headphones to a compatible DJ device (e.g., the DJM-V5) for instant SonicLink connection. For mixers/devices without SonicLink, use the HP-TX01 transmitter (sold separately) to connect smoothly
• Flexible Design for all DJ Styles - With a swivel mechanism and flexible headband, the headphones are comfortable to wear whether you’re listening with 1 or 2 ears, or resting them on your shoulders
• Durable Construction - The extendable slider is built from rugged die-cast aluminium for long-lasting durability. Tested against strict international standards, it delivers the reliability professional DJs demand
• Lockable Cable Design - The connection between the headphones and cable uses a secure bayonet locking mechanism to help prevent accidental disconnection
• Minimal Design - The minimal design blends naturally into any setting while balancing form and function
• Rich Low Frequencies and Balanced Sound - While they’re compact in size, the HDJ-F9 headphones are designed for precise monitoring, even in loud DJ booths. They deliver powerful, full-bodied low frequencies and a well-balanced mid and high range with minimal distortion
