Monitoring tracks on a heaving dance floor is a breeze with the HDJ-1500s, no matter how rowdy the party gets. Sound insulation around low and medium frequencies (300 Hz to 1,300 Hz) has improved by an impressive 4 dB compared to the HDJ-1000s thanks to the innovative sound-isolation chamber on the bass reflex port, which eliminates background noise.The HDJ-1500s’ moving hanger and hinges are composed of rugged yet lightweight magnesium alloy to withstand the rigors of professional use. Plus, the single-sided cable can be easily replaced if it gets damaged, further prolonging the life of the headphones.The narrow ear cup design creates a tight seal on your ear to block out external sound, while the low-resilience urethane memory foam ear pads make sure the HDJ-1500s are easy on the ears even during prolonged use. The included ear pads can be replaced with the HDJ-EP01s’* -open-cup protein leather ear pads which sit around the ears and are sold separately -so DJs can choose the best option to suit their comfort and listening style.The compact carrying pouch means the headphones can be safely transported to the club or the studio in style. The HDJ-1500s also fit perfectly in the slim and lightweight HDJ-HC01 carrying case. Accessories such as USB memory sticks and SD cards can be stored in specially designated pockets within the carrying cases for added convenience.With high-quality components, the HDJ-1500s deliver perfectly balanced sound across all frequencies. The headphones feature copper-clad aluminum wire voice coils, large 50 mm driver units, rare earth magnets and 38m-thick diaphragms, guaranteeing accurate reproduction of deep base notes and clear delivery of other low to medium frequencies, such as kicks and snares. Output levels are 1 dB greater than Pioneer’s HDJ-1000 headphones, and a lower impedance offers even greater sensitivity, so DJs get pristine sound reproduction every time, regardless of what device the HDJ-1500s are hooked up to.
