If you were wearing the headphones at the time (that is, they're not coiled up in your pocket), I assume you'd hear Siri's responses. If you were actually using the phone at the time, you'd notice the screen changing as well.
It's a pretty pointless hack if it assumes that the victim has headphones attached, but is not actually wearing them. Do people actually do that?
I've occasionally had people on the radio say something that sounds close enough to "Hey Siri" that Siri activates and starts passing the rest of the radio conversation to Apple. If I don't stop it quickly (by pressing the home button), it eventually makes Siri spew and error message.
Maybe I should start a band and release a song called "Hey Siri, what's the weather?", using that phrase in the chorus. Everybody with an iPhone will be annoyed every time the song is played on the radio :-)
Not only that, but you would hear the command being given as well. The attack works by using enough transmit power to turn wires into antennas, the headphone wires would pick it up as well. Depending on how it is done, the volume could be quite loud as well. You would probably notice this happening. Also, this attack is of course illegal by existing laws. Not only hacking laws, but FCC radio transmit laws come into play here.
Look on Youtube for "Xbox Bing"...

Or switch to wireless headphones, which is probably where Apple is headed in order to make their devices thinner.
Eventually the iPhone will be tattooed on your arm with a laser (that's thin!) and Siri will babble directly into your mind.
Utopian future, here we come!
Maybe you should not have married an adolescent? Isn't that illegal? (bolding added by me to quote)
In a post-9/11, Charlie Hedbo, London Subway attack world, anyone walking around with an overstuffed backpack that's emitting radio waves might get a lot more than they bargained for.
Siri: "Okay, here is what I found for 'I'm walking around looking suspiciously like a terrorist.'"
Those French are so clever. For their next trick, maybe they can figure out how to do capitalism.

Some Android devices do feature voice recognition for Google Now access, which could thwart the potential hack. Apple has no such functionality built into Siri yet.
I'm calling B.S. on the ability to spoof a button press. It's nearly impossible to do by inducing a voltage differential picked up by an antenna.
Seems like quite a stretch, but I guess some dorks need a useless hobby.
Here's a security tip. If you see an acned teenager or a creepy long beard eating doritos and drinking mountain dew at the coffeeshop and they have a pair of cans and a morse code tapper hooked to a giant backpack.... stay 16 feet away. You'd probably have to stay that far away to avoid the smell of his momma's basement.
Are you more upset that the "dorks" attempt these hacks, or that they succeed?
Its a nice trick, but generally useless. So I guess I don't see the point. People ought to use their talent towards the betterment of humankind or the acquisition of wealth and this is neither. It's just someone trying really hard to be annoying.
By that do you mean the audio sync issue where the audio lags the video by a fraction of a second due to the delay in encoding and then decoding the bluetooth signal?
If so, then there is already a bluetooth audio codec (apx-ll, I believe) available specifically for low-latency transmission which eliminate the lag (something on the order of 40 milliseconds). It works quite well but both the transmitter and receiver need to have it included (and I don't think it even requires BT4, it works with earlier revisions). All it would take to make it main stream would be for someone like Apple to decide to include it in iOS.
Even without that codec (which probably has some extra licensing associated with it), it's highly dependent on your headphones. On mine, for video on my iPad mini, there is a noticable delay but it is very minimal. Kind of to the point where you don't really notice it if you aren't looking for it. For non-video, intermittent audio (ie, alerts, UI clicks, and such) it's more annoying. But I attribute that in part to Apple's aggressive power saving logic on my iPhone 5S. It takes a finite amount of time "fire up" the audio and bluetooth circuits.
