Sony MDR-100AAP h.ear on: made for beats
The Sony h.ear on headphones feature an air vent on top of the ear piece, as well as Sony's Beat Response Control technology, so that they'll faithfully reproduce even the fattest beats. Meanwhile, the 40mm drivers in the circumaural earpieces block out ambient noise and feature a 5 Hz - 6- kHz frequency response, for authentic, true to life audio. Add that to the fact that these headphones are High-Resolution Audio compatible, and you know Sony means business!
