Subject: Re: Insert earphones for ERP studies From: Gerry Stefanatos <gstefana(at)EINSTEIN.EDU> Date: Fri, 9 Dec 2005 14:50:09 -0500Etymotic Research produces some of the best earphones. You will probably want a model with easily replaceable or disposeable inserts. I am not sure which ER model provides this, but I think it was the ER-4. Gerry Gerry A. Stefanatos, D. Phil.

The earphones should block external sounds and should also be electrically shielded. Can any of you recommend earphones of this type that would work well for ERP experiments? Thanks!
