Hi, I just want to share experience using SE handsfree. This info might be useful for SE manufacturer to improve their accessories.
If you want to change tracks/radio stations using SE handsfree you still have to use the phone. Difference with other manufacturer's handsfree which can change tracks/radio stations just using the button on the handsfree.
Can SE solve this problem?

What kind of handsfree do you have, a bluetooth one or the normal wire one..

never mind any ways you can't change the channel with the hands free....
I don't call it "the hands free", it's just a headphone..
but with the magic word you can call, answer and reject calls really hands free...
