A while back, Scott Marshall posted about a little earpiece that slides behind the ear, and the speaker sits just outside the ear, thus allowing ambient sounds to be heard. This is a single earphone only. I bought one, and really like it. It is called the Williams Surround Sound earphone. I bought it from Cardinal Sound in maryland, but a friend told me that C Crane also sells it at even a lower price. I paid $13 including shipping. You can find Cardinal Sound at: www.cardinalsound.com You can call C. Crane at: 800 522-8863. Andy
