This, unfortunately, mostly depends on your handset model - not all current Windows Mobile devices are able to use a mono headset when not in a phone call. (I assume you're trying to use a mono headset and not "real" A2DP stereo headphones. With the latter, the sound transfer is very easy to set up.)

I've posted a full tutorial on all these questions to http://www.smartphonemag.com/blogs/index.php?blog=3&p=1398&more=1&c=1&tb=1&pb=1 . Feel free to tell me if you still can't set up the connection.
