Sony´s Pro Audio department has a real winner on its ears with the MDR7506 large-diaphragm foldable headphones. These "phones have everything a musician needs for the studio or on the road. We probably don´t even need to mention the excellent Sony sound quality, but it´s there, with smooth frequency response from 10Hz to 20kHz. Closed-ear design gives you great comfort for long sessions, exclusion of external noise, and no leakage for when you´re recording. But that´s just the stuff you´d expect — the MDR7506 are also supremely rugged and collapsable, making them the most road-worthy of headphones for DJs, drummers playing to click tracks, engineers, and others. A soft carrying case comes supplied. Stereo Unimatch Plug with 1/4 in. and 1/8 in. applications. Gold Connectors and OFC Cord for reliable and stable signal connection and transmission.
