AlphaTheta HDJ-F9 Professional Wireless DJ Headphones

While they're compact in size, the HDJ-F9 headphones are designed for precise monitoring, even in loud DJ booths. The newly developed 40mm drivers deliver powerful, full-bodied low frequencies all the way down to the sub-bass range. The bass-reflex chamber at the top of each housing accurately reproduces the attack of basslines and kicks, delivering tight, clearly defined lows. And the PEEK-PUPEEK composite film diaphragm suppresses unwanted vibration, providing a well-balanced mid and high range with minimal distortion. With an optimized internal structure, the headphones achieve a high level of sound isolation compared to other on-ear models. So, you can monitor your music comfortably without turning the volume up too high, reducing strain on your ears.

• Whichever monitoring style you prefer, the HDJ-F9 headphones adapt to you. The swivel-mounted hangers and flexible silicone headband are comfortable to wear, whether you’re listening with one ear or resting the headphones on your shoulder.
• To ensure long-term durability, the adjustable slider is made from tough die-cast aluminum. The headphones have passed international durability tests, offering the reliability that professional DJs need.

• Using the HEADPHONES CONNECT app on your smartphone, you can adjust the color and brightness of the Status LED to match your mood or musical style. You can also rename the headphones and configure the auto-power-off function and voice assistant settings for Siri or Google Assistant.
• The built-in Find My Headphones feature lets you locate your headphones by playing a sound, and on Android devices, it’s also compatible with Find Hub. The app provides firmware updates and tips, along with support functions to give you extra peace of mind.

With multipoint Bluetooth pairing, you can connect your headphones with 2 devices at the same time—for example, a smartphone and a PC—so you can switch between them effortlessly. There’s also compatibility with Google Fast Pair and Windows Swift Pair, enabling quick one-touch pairing with Android or Windows devices.

• With the Status LED illuminated, the battery offers 7 hours playback when connected via SonicLink, and 13 hours when using a Bluetooth connection.
• The battery charges from empty to full in approximately 2.5 hours, and a 30-minute charge gives around 2.5 hours of use.
• 3.9' coiled cable with L-shaped plug included, enabling wired monitoring and extendable up to approximately 9.8'.
• Built-in microphone for hands-free calls.
