Neodymium dynamic drivers deliver precise sound

Lightweight 1.57 in neodymium dynamic driver units enable the headphones to deliver a punchy, rhythmic response to even the most demanding track. Combined with a highly sensitive diaphragm, you’ll be able to turn the headphones up louder and still enjoy clear, precise audio across the spectrum.

Tight bass with Beat Response Control

Beat Response Control technology delivers tight, deep bass response, making it perfect for low-end focused music styles. An air vent maximizes airflow within the low frequency range, optimizing the efficiency of the diaphragm to enable more accurate reproduction of bass rhythms.
