The Pioneer DJ HDJ-CX are lightweight professional on-ear DJ headphones designed around comfort, isolation and portability. At only 136 g without the cable, they are far lighter than most full-size DJ headphones while still using a rugged steel-core headband and 35 mm drivers with a specified 5 Hz to 30 kHz response.

Very low weight
The 136 g weight is the headline feature. For DJs who wear headphones for long sets or dislike the clamp and bulk of large over-ear models, the CX is designed to reduce fatigue without turning into a fragile consumer headphone.
Sound and isolation
The 35 mm drivers use a composite PEEK-PU-PEEK diaphragm, while bass reflex chambers reinforce low frequencies. Additional sound-insulating structures help keep booth noise outside the cups so cue details remain easier to hear.
Durability
The headband includes a steel core and uses a ladder-like structure for flexibility. The headphones passed the MIL-STD-810H shock test as well as Pioneer DJ’s own durability testing.
