I have the Sony Ericsson kit, and love it other than the fact that i can't get the phone mute to work with the empeg at the moment, but i haven't narrowed down what the trouble is just yet. It's sounds great and the voice recognition works as advertised. I did have to change "home" to "at home" to get it to recognize it 100%, so you might have to play around with some of the wordings to make them work all the time, but once i got that down it's worked pretty flawless. (other than the mute thing. hehe. but that might be a wiring problem or something else... like i said i'm tracking it down now.)
