Sony MDR-7506 - BLACK CLOSED MONITOR HEADSET

(This text is machine translated) The broadcast standard in the US and Europe. A high quality, not bulky, reference headphone. Perfectly enclosed and surprisingly light, the MDR-7506 has been designed to be comfortable during extended periods of use, making it ideal for use in broadcast and recording studios. A 40mm PET diaphragm and neodymium magnet ensure performance that far exceeds the requirements of digital signal sources such as CD, CF and HD.
