I know it fits the CS540 because that is what I have but I cannot speak to the other models.

I don't think it will. I originally purchased it for plantronics M50. It did not fit. There is a foam piece in it that blocked it from a perfect fit. It was a waste for me.

I am not sure of the model number that you referenced here (73680-06) as I could not find it listed on Amazon. However, the Plantronics 77043-03 definitely is a suitable replacement for the Bluetooth headset that comes with the Plantronics Calisto Pro. I am using that replacement with my Calisto Pro and it works great, just as good as the original, if not better. It looks identical.

My boss has a Plantronics one (old model from approx. 7-10 years ago) and it fits this phone and works fine. If the handset lifter fits, it will work.

Same thing happened to me. It's supposed to come with 3. I had to go to plantronics website and order the correct size.

Replacement kit fits easily. The cushions aren't as soft as original earpieces but acceptable.

Sorry, don't know the answer to this one. However, Plantronics' techs are not that difficult to get hold of, and they are very helpful.

This bluetooth fits well. But then it would depend on the ear shape and size too.

It came with 3 sizes of soft (silicone?) parts that go into the ear. They are interchangeable to get the right fit.

Sorry, I don't know. I bought them for a Logitech headset that has oval ear pads and they fit them perfectly.

This model does fit the MM 550X, along with several other models via included replaceable frame bracket. Very easy to replace so that you always have a fresh charge, and highly recommended due to high energy needs of noise cancelation. I hope that helps.
