I've tested these using them on both ends and got muffled sound back. It seems that one of the microphones is better than the other, so I may have a defective unit. Anyway the PTT functionality is there and it's a lot more practical (and quiet) to use than the regular "walkie-talkie" radio by itself.
Disappointment:
For some reason the plug does not stay securely in the telephone. Most movements will disconnect the plug. Very disappointed and would not recommend.
Probably great.....:
Probably great for most activities, but communication between two Harley riders is definitely not one of them. Just another failed experiment for me.
What's with the short cord:
If the cord was 1 foot longer, 5 stars. I don't get it. Is someone saving 2 cents for every one of these? Or.. make the earpiece cord shorter and the thicker part longer. Would have been great if it came with a removable ear clip/wire but not really complaining about that. Maybe a future feature. Then again, if they can't make the cord 1 foot longer, I wouldn't expect any other luxuries. Functionally seems fine.
