The Sony MDR-7506 professional headphones are all about comfort, durability and natural audio monitoring. These closed-back production headphones are great for live-broadcasting, as well as being comfortable enough to wear for long periods of time in the studio. They produce high sound-quality, utilising powerful Neodymium dynamic drivers within the closed-back housing (acoustically tested) to ensure near-perfect uncoloured sound. The Sony MDR-7506 headphones produce sound with unrivalled clarity and attention to detail - great for Broadcast and Studio Audio Engineers. They operate with 63 Ohms of resistance, ideal for all types of audio monitoring, and the ergonomic ear pads, adjustable headband and lightweight design, are more reasons why the MDR-7506's have been the industry standard since their original release in 1991.
