Well, Logitech responded to my issue via email and here is what they had to say:
"Thank you for contacting Logitech Customer Care Team and I am glad to assist you.
I understand that you have ordered UE 900s and you are concerned that you might not have received the correct one. Let me help you with this.
Can you show us the picture of the box which shows the White writing on a color Blue plastic? The UE 900 and UE 900s are the same which the writing should be on a Black plastic. Please click this link as your reference:
We have also tried to search online as you have claimed that you have seen some pictures of the UE 900s with the Blue plastic and we have not found one.
Please try to provide us the picture of the box by attaching it on your response and if you can also include the links of the pictures that you have mentiond with the Blue plastic. We are concerned about this at it may raise a confusion to our customers."
So basically they are saying that the UE 900 and UE 900s look the same and that the picture that we've seen comparing the two side by side is incorrect. I'm going to send them a link to the photo of them side by side and see what they say, but I assume it will be basically the same response as I just received.
