The S15 insert earphones provide acoustic stimulus delivery for neuroscience research using 7T and 9T fMRI scanners. The S15 earphones employ a cable that has been designed to be safe and robust against the higher RF frequency and power levels employed with higher-strength scanners.

The S15 insert earphones provide high-quality acoustic stimulus delivery while attenuating scanner noise. They are small enough to fit within any head coil, and can be covered with circumaural muffs for added protection if the coil allows. Replaceable Comply(TM) Canal Tips ensure sanitary conditions.

Frequency response equalization is achieved by pre-filtering stored digital stimuli. Equalization filters are provided and can be used either within Matlab or with a stand-alone filtering program (provided). A small power amplifier is required.
