Well the president of the company did the video interview with Gotham where he said they could basically tune them to whatever band. Their official website indicates that ordering them in TV5/6 is also an option so I’m just guessing here but I suspect if you contacted them and asked for a different band it might be possible. We’ll see. I expect it would be a factory mod to get it changed to something different.
I’m not on Facebook anymore but thanks for the link.
Also, they demo the voice prompt control in the video so I’d say that rumor is confirmed.
