The Sony MDR-MA900 Stereo Headphones feature an open-air, over-the-ear (circumaural) design with flexible fit, neutral playback and a 9.8' cable to give you ample freedom of movement when connected to your A/V device. Their high output 70mm drivers with Neodymium magnets produce an impressive 5.0 - 40,000 Hz frequency range. The earcups as well as the headband are padded and adjustable for comfortable extended wear and a secure fit.
An open-air design delivers not only a lightweight, comfortable, and airy feeling, but also creates a natural sound field that mimics listening to music without headphones.
High-Power Neodymium Drivers
360 kJ/m3 Neodymium magnets provide rich bass and clear mid-range response.
Specially developed 70 mm driver units deliver high-resolution sound with a wide, dynamic range.
Perfect for Home Use
A 9.8' (3.0 m) single-sided cable with Unimatch plug allows connection to various audio devices.
Acoustic Bass Lens
Acoustic bass lenses help deliver rich bass response by concentrating the bass impact at the center of the driver.
