I have no experience with the headsets in your post. I, like Siriusjoe think these would be very uncomfortable with a helmet on. I would wait to get some feedback from someone who has actually used them on a motorcycle.
I use Scala Rider Q2 headsets. They work flawlessly and are very comfortable and easy to install.They are a little more pricey than the ones in your post.
Nothing worse than having gear that is not comfortable.
I've never used or even seen that one but it did get some fairly decent reviews. You can do like I did and watch e-bay for some deals. I got a pair of Chatterboxes and the helmets they were attached to for $100. The helmets alone were worth that. Good luck.
I played with the idea of those Firefox communicators. (for price reasons) They seem like they would work "in theory". You can take a mike and press on your throat and it will pick up your voice, but it is muffled. I would assume those would be too. But I finally decided to bite the bullet and pay 2 Ben's for a set of the Scala Rider "Team Set Pro".

Who would have thought I would grow up to become "Spatially Educated" and play Connect-the-Dots for a living.
I have the Sena SMH-10 also and like it. It works great with a full faced helmet and the open faced helmet, if the mic is not exposed directly into the wind. You can talk to your buddy up front, use a blue tooth phone, or a mp3 connected to a blue tooth transmitter. My iphone also has blue tooth so I listen to music from it. The speakers in the helmet work with no loss of comfort.
You can also talk to two or three people at the same time.
