Subject: MR-compatible headphones: Koss medical ESP 900 From: Yoshiko Yamada <yyamada(at)DARKWING.UOREGON.EDU> Date: Mon, 8 Nov 2004 15:58:15 -0800Hi, I'm wondering if anyone on this list is using or knows someone (or a lab) who is using Koss 'medifcal ESP 900', which is a model of MR-compatible headphones, for auditory fMRI studies. When I talked to a sales rep at Koss, I was told that although this model is MR-compatible, each lab makes a bit of modification to meet their needs. We are wondering what kind of modification is made and why since sales rep didn't know the details about what was done to the headphones. Our lab has been looking for a set of MR-compatible electrostatic headphones for auditory language fMRI studied and considering purchasing this model, but we'd like to gether more information about compatibility of the headphones with fMR image acquisition. Thank you for your info!
