    We have developed high fidelity MRI compatible headphones for fMRI experiments. Scanner manufacturers, and several small companies, produce MRI compatible headphones which operate under various physical principles including air tubes, magnet-less electrodynamic ( and electrostatic transducers ( These systems are often intended for communicating with and for providing diversion to subjects, and typically have a restricted, uneven frequency response. Our headphones have a smoothly varying and wide frequency response. The new headphones operate electrodynamically, like those of Confon but, in contrast to Confon, use an isodynamically (see reference) (iso – uniform, dyn - force) driven lightweight membrane.
