Mystery Birthday Present

Okay, so here is what my work colleagues bought me for my birthday gift...(this is what came inside the jiffy bag) -

...and this is the contents of the blue box -

- (with give-away sticker obscured)...Looking closer at the object itself, it takes a single AA cell for power, has just one switch (with two settings), a small red light and what looks like a small microphone on the top -

I twigged what it was rather quickly... ;)

So, can anyone guess what it is? Answers on an IP packet... ;)
