LOL. I knew it would be somewhere soon, as I knew MP3 was patented somewhere in 1997/1998. Coincidence it's exactly within this week

I know exactly what you mean. I can *still* hear an Osram lightbulb powering up, I can still hear tube lights humming, and I hear all kinds of noise coming out of TV speakers that nobody else seems to hear.
Some time ago I bought a Logitech bluetooth receiver, so I could play music from my laptop through my speaker system. When connecting the laptop's dock directly to these particular speakers, there's a very irritating humming noise. My previous computer had the same issue, but this wass resolved with an extra/dedicated sound card. Because I didn't want to attach an external, dedicated sound card to the dock just to play some music incidentally, I bought the bluetooth receiver. All was fine.
Until I bought a desktop computer.
Now I sit in the computer room more often, and the dock has gone, but I left the receiver in case I'd want to use the laptop in that room, for some reason. When sitting there, I heard a very irritating sound, every few seconds:
"iiiii..... iiiii..... iiiii..... iiiii..... iiiii....."
First thing I thought: "Nooo! Not graphics card or mainboard coil whine. One big reason to choose the components for this desktop were the reviews, mentioning the absence of coil whine! FFFFF...."
So I started powering down stuff, and disconnecting everything. The sound continued, until I disconnected the bluetooth receiver. It turns out that, when not connected to anything, the receiver keeps broadcasting for connection (and a dim, blue light flashes), and when it does so, it makes that irritating sound.
It was never mentioned in any of the reviews, and because I've been using it with the laptop for months, I can't return it.
Conclusion: either everybody at Logitech and all of the reviewers are deaf, or no-one's ever been in the same room with that thing while it wasn't connected.
