Negative Profile Earphones

I just bought a set of Shure SE-215s for a long motorcycle trip to help protect my hearing and allow for a COM system between riders with a microphone.  I now can't see myself using a headset without a negative profile.  Does anyone know of any major brands that make noise cancelling headsets with a negative profiles?  I am aware of the ones from Shure and a few boutique dealers, but I am not aware of too many from any other manufacturer. 

Never mind... They're IEMs.  If their like the Shure SE215, then their an IEM.  Now, this is a search able query, it shouldn't be asked again.
