I would also like to share my experiences with this issue:
Bought one pair from Thomann January of this year, unfortunately both speakers had exhibited this problem, so I was forced to return them. Sadly I did not note the serial numbers.
Learned about the new hardware revision from this thread, so I thought I'd order another pair from a local store this month, but they still had the coil whine present, so it was another quick return. In both cases only the power cable was attached.
Serial number was: IUD04-61YFAD**-*****
And on the bottom of the speakers there was a sticker with 220303** which probably indicates the manufacturing date? But I am not sure how to read that so it might be something completely different, so take that with a grain of salt.

Edit: The second pair I ordered came with the firmware that allows for the 80 Hz low cutoff setting, so it had to have been at least version 1.2.0.

the number on the bottom is actually the serial number according to the official IKMultimedia support. The serials of my first speakers were: 210401** and 210400**

BTW I decided to return the second batch and just use the first @110V done

Here the Bezel difference I mentioned before, see the right looks more filigran:

The solution is to plug monitors to another power strip than computer. Especially if you're a Mac user. It is a common problem in mac environments with audio hardware. On my pair I heard the total work of my processor, loud noise and
squeak modulated depending on my activities on the computer. Hope that advice helps a few users. All the best.

I kept the first batch and it works perfect @110V no noise whatever

Just had the same problems in a 230v environment and i know the correct solution:
Use balanced XLR cables! I have used expensive high quality audio cables and had so much noise in my MTM´s that i though there is no way to solve it. After switching to new cables (Klinke to XLR BALANCED) all noises are gone completely!
Bought "Nuosiya balanced audio cable". Try it ;)

I also have balanced audio cables.
Which noise does disappear for you?

The noise @ 230V also appeares here without any cables attached.
It is produced by the voltage generator and not emmited by teh speaker itself.
You onluy got that noise with cables attached ?
