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.
