Monitor mixes in comfort for long periods of time with the higher-quality audio, advanced durability and improved fit of the HDJ-S7 headphones. Thanks to a high definition 40-mm driver, they’ll deliver the same high-resolution 5kHz to 40kHz sound as our flagship HDJ-X10 over-ear headphones. Ideal for DJ monitoring, you’ll pick up on greater separation of rich bass tones and clear mid-to-high frequencies.
