Does anyone use (or know someone who uses) non feromagnetic (piezo)
headphones for magnetoecephalography (MEG) experiments? Usual sound
application is via elastic tubes from speakers outside of the
magneto-shielding booth, with really bad sound transmission values.
Piezo headphones might provide good sound transmission without
disturbing the magnetic field. Information on providers of such
equipment (and approx. prices) would be highly welcome. Is it difficult
to install? Does it need shielding tubes for the wires?

Thanks,
Christian
