AlphaTheta HDJ-F9 Headphones

INFORMACIJA

SonicLink is the answer for artists who demand high-quality sound and reliability from their headphones but also want the freedom to move around and express themselves without the restrictions of cables. Even in wireless mode, the HDJ-F9 headphones produce crystal-clear sound and a dependable connection, while the SonicLink Touch Pairing with compatible DJ equipment offers effortless setup.

The headphones’ minimalist design blends naturally into any setting, combining advanced features with a refined look. Using the dedicated HEADPHONES CONNECT app, you can even customize the color and brightness of the Status LED so it complements the theme of the event or music genre you’re playing. With a combination of ultra-low latency and outstanding comfort that’s hard to find in conventional wireless DJ headphones, the HDJ-F9 model offers an experience unique to its on-ear design.

The HDJ-F9 headphones feature SonicLink, AlphaTheta’s own wireless technology. SonicLink delivers the high-quality sound, powerful volume, and ultra-low latency that DJs need – all wirelessly. Without cables, you can monitor your mixing, and even scratch, accurately. Latency is as low as 9 ms, so you can stay fully focused on your performance without noticing any delay.

And with the newly added SonicLink Touch Pairing, you can instantly connect to compatible DJ gear, such as the DJM-V5, simply by touching the headphones to the mixer or other supported unit. By using the separately sold SonicLink Transmitter HP-TX01, you can connect your headphones to a wide range of devices.

While they’re compact in size, the HDJ-F9 headphones are designed for precise monitoring, even in loud DJ booths. The newly developed 40 mm 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-PU-PEEK 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.

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, configure the auto-power-off function, and choose whether a button on the headphones can be used to start and stop Siri® or Google Assistant™.

The built-in Find My Headphones feature lets you locate your headphones by playing a sound. 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.
