The HF Wireless from Numark are professional wireless or wired headphones designed to free the DJ from the restrictions of traditional fixed-length headphone cables. The HF Wireless uses Bluetooth 4.0 technology with NFC pairing, which provides up to a 30' range and a built-in battery that affords 10 hours of music playback from a single charge.
The leatherette, over-the-ear earcups provide acoustic isolation and rotate for hands-free, single-ear monitoring. The 40mm drivers offer a frequency range of 60 Hz to 20 kHz, while a 32 ohm impedance allows the headphones to work well with low-output devices. Additional features include a compact, collapsible design with a built-in microphone, a 4' stereo 1/8" (3.5mm) cable for wired operation, and an 1/8" to 1/4" adapter.
