I don't have any comparison information to give you, but I can tell you about last year's chatterbox. My husband and I have used them. They have positives and negatives...
1) seem to have good range
2) clarity is great as long as they are set right
3) the charge lasts all day
1) the earphones hurt like crazy unless you get them in there perfect. (need to switch to in the ear vs. over the ear)
2) wind noise can be a problem if you use the voice activation.
I like them when we go on long rides, or with a large group where my husband takes the lead and I bring up the rear to make sure we don't lose anyone, but for short rides, we both prefer it to be quiet in our helmets....
I even prefer the PTT (push to talk) button because I constantly talk to myself in my helmet....or sing a little tune and I'd rather not have to worry about bothering someone else.
Overall....I really like having them for when I want them! How's that for vagueness!!??
