Hi Jon,
welcome to Beoworld, unfortunately i dont know the answer to your question so looked through the excellent Products section on the Beoworld main site, and on finding the beocom3 i realised ive never seen this phone before as its not available in the UK.
I then checked out Earset1 for home phones, but it doesnt say its compatible with beocom3.
Im sure you have come to the right place to get your answer and no dought someone will come up with some information for you.
