Subject: Question about In-Ear Microphones From: "Benjamin, Eric" <EMB@xxxxxxxx> Date: Wed, 1 Feb 2006 11:55:47 -0800You can do very well using the Knowles FG capsules. These are hearing aid capsules that measure 2.5mm X 2.5mm and the FG-3329 and FG-3629 types have a frequency response that is quite flat and very low noise for the size. They can be purchased in the US from Digikey http://www.digikey.com/digihome.html for US$25.25 in single quantity. For me, in the US, the Sennheiser capsules are essentially impossible to obtain. For you, in the UK, it may be different. If I can help out, please feel free to contact me off-list. I wonder if anyone has a web page which details the difficulties and the actual how-to-do-it parts of HRTF measurement?

I found a couple of threads suggesting the Sennheiser KE 4 to be a suited mic to do the job but the threads were from 1995. So I was wondering if anybody knew of other (better? cheaper?) alternatives available nowadays. I also would be thankful for any hint where I can buy any of them. Thanks in advance for your help.
