I am looking to replace an aging electrostatic, MRI compatible headphone se= t. There are some headphone systems marketed as MRI compatible but I either= don't like the quality (even though they are affordable) or they are too e= xpensive. I have read that Stax and Koss make electrostatic headphones that can be mo= dified so that they can be used in the scanner. Does anybody know how these= would need to be modified not only to be MR-safe but also don't cause arte= fact? Worried about copper wiring etc. If someone has advice/experience the= y would be willing to share on specific models I'd also be very grateful.
