Hello everyone,
 
I recently received a pair of IEM's from a family member.
 
Just some background information, my family member works under Logitech to create custom mold's and designs for in ear monitors.
When he gave me these as a gift, he said they were "generic casings," but had the guts of Ultimate Ear 11's.
 
I have supplied several pictures in this post.
I would like to apologize for the lack of focus, All I have is my phone camera and I couldn't get it to focus directly inside the monitors but I did as best as I could with the lighting.
 
Upon further inspection, there seems to be dual armatures, which can definitely narrow down some of the results.
UE11's are listed to contain quadruple armatures. But to my limited knowledge, I can only see two.
 
Of course, it's very much possible that they aren't the UE series as well but considering he got them directly from Logitech, it could help narrow down the results.
 
I can definitely post more pictures if needed.
 
Any thoughts would be greatly appreciated!
