Designed for previewing tracks, DJs can precisely analyze sounds 50mm drivers guarantee the clear sound and accurate bass response that DJs expect Because style and comfort are not just for professional DJs, Hercules has created the HDP DJ-Adv G501 headphones. Designed for both advanced and amateur DJs, they provide high-quality sound reproduction and excellent listening comfort. Sporting a shape similar to the professional HDP DJ-Pro M1001 version, the HDP DJ-Adv G501 model is distinguished by its black lacquer finish and green highlighting elements. Professional Sound Designed for previewing tracks, the HDP DJ-Adv G501 headphones allow DJs to precisely analyze sounds, thanks to their 10 Hz to 25 kHz frequency range, allowing the wearer to hear precise audio reproduction of their tracks, and thereby effectively prepare their mixes. The headphone drivers are 50mm in diameter, guaranteeing the clear sound and accurate bass response that DJs expect. Their low impedance (32 ohms) and sensitivity of 102 dB at 1mW provide a powerful audio level which does away with the risk of being overpowered by PA system speakers. The ear components pivot along 3 axes of rotation, and can be folded for travel 3-Axis Rotation The ear components pivot along 3 axes of rotation: each ear-cup swivels vertically about its hinge by 180 degrees, while the hinge swivels 90 degrees horizontally and toward the inside of the headphones by 120 degrees, providing great flexibility for DJs carrying out one-ear monitoring. This mechanism also allows for the headphones to be folded and easily transported in a carry bag. Their cable, which measures 6' in length when extended, can be connected to the left ear-cup for right-handed DJs, or to the right ear-cup for left-handed users. What's in the Box?
