Not quite what you want, as these are not "in the ear" but are "on the ear" - the wiRevo bluetooth stereo headset. Currently on sale at Fry's for $20 plus shipping.
Here's the link:

Shows $49.99 normal price, add to cart to see new price, which is $19.99.
I use these while exercising - nice thing is they use a normal mini-usb (same as the Mogul) to charge, so there's one less unique charging cord to worry about like on some of the Jabra stereo bluetooth headsets.
These also include a microphone for making calls. Sound isn't too bad - check reviews on Google.
Hope this helps, --TonyK.
