AlphaTheta HDJ-F9 Professional Wireless DJ Headphones

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 msec, so you can stay fully focused on your performance without noticing any delay.

And with the newly added SonicLink touch pairing function, 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.

Rich low frequencies and highly effective sound isolation

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-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.

Durability and minimal design to support every monitoring style

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.
