What does it say on the thing(s) that have the US plug,  picture would be useful

see pics below, thanks

Unless you can give the full details of these 120V speakers, make/model nobody can say and there is no point guessing.

It is not the adaptor that you have used, so another one won't help as it will still present 240V to your 120V speakers.

first bit:
I'm currently getting pics...

So was the Ebay seller wrong to state "Power source is US plug so will need an adapter" ?
Should they have supplied the transformer as well?
Thanks

Those speakers are 120v  only  you might be lucky and they have a fuse.

I said they were 120V in my original post. 
No they don't have a fuse. 

The adaptor for the 9V device had a 13 amp fuse when I tested the speakers. But seeing as the sleep machine is such a low powered device, I have since put a 3 amp fuse in it. 

Someone already said even a normal adapter would not have been suitable. This leads me to think I should have therefore been supplied with the transformer for the speakers?

Please can someone tell me if that's true?

And if the speakers are now damaged, is it possible to fix them?

Thank you

So why did you connect a 120V device via a simple adaptor plug to a 240V supply, if you knew that they operated on 120V?

The adaptor plug simply allows a 120V plug to be plugged into a 240V 13A socket but it does not change the voltage.

Here is an example of a mains convertor which converts 240V down to 120V which would have then powered your 120V speakers:

If there is no internal fuse in the speakers that can be replaced, then you have fryed them by giving them twice the required voltage!

The seller informed you that they were 120V and did not have a transformer to supply to you and was not obligated to do so.

theoretica

If the seller said they would work with just an adaptor, yes I think you have grounds for complaint - might be easiest if a bit disingenuous to simply return them as not as described as they don't work and not go into why you think this is.  They will probably be repairable, but I suspect it would not be cost effective and it sounds like you don't have the skills to do so yourself.

Thanks for the info about transformers.

Q: "So why did you connect a 120V device via a simple adaptor plug to a 240V supply, if you knew that they operated on 120V?"

A: Because the adapter said: "120V - 240V"
As I said before; I thought that meant it included all devices from 120V - 240V could be connected to it.

OK so it's not the same as voltage, but if I was looking for house number 16 and the street said "Numbers 10-20", I would assume I was in the right area. That's what I was thinking when I saw "120V - 240V". 

Two people have assumed that everyone knows it means the higher voltage. I did not know that. 
I now know that - thank you for the lesson!

"The seller informed you that they were 120V and did not have a transformer to supply to you and was not obligated to do so."
The seller never mentioned a transformer or that the speakers were 120V. They just said that they will work with a UK adapter.

"If there is no internal fuse in the speakers that can be replaced, then you have fryed them by giving them twice the required voltage!"

If you do decide to buy some more of these, the Logitech X140 model number S-0264A is for 120V and model number S-0246B is for 240V with a standard 13A mains plug.
Looks like you were unlucky as all of the ones that I have seen on eBay are the S-0246B model.

Thanks a lot, that's good to know.
The seller has been great throughout. I told him that I accidentally fried his speakers, and explained what I learned in this thread, and he has refunded me straight away. 

Thanks everyone for your help.
