I am still looking...
I have the Jawbone ERA and had nothing but troubles with it. I have had to do a hard reset on it many different times, when listening to music is breaks up on/off and at random times, when it works it works great.
I have had many people report that they cannot hear me or I sound muffled, this is not all the time, it seems to fade into this mode, and once there is stays.
Whenever this happens I have to delete it form all my devices, then do a hard reset on it and then pair it again. This should not happen.
This is my second unit.
Personally I hate it...
(yes it has the latest firmware updates, as do all my devices)
As far as working with Siri, it works fine if your have a single question, multiple items it gets all out of sync and I have to power it off and on again to be able to use it.
Now before you try and troubleshoot this for I have tried everything, Jawbone tech support (worthless in my mind) I have used it with 3 different phones, including my iPad. These problems all remain unchanged. I have given up on it.
I refuse to let them send me another. I will file it along with my other useless electronic items and try another headset.
My next will be the new Bose.
