Not from Aliexpress and I haven't ordered one but this seemed like the least inappropriate place to post it in case others found it useful, the TOTO Otohime Toilet Sound Blocker:
I saw this device in Japan and I just have to have it. I have a guest restroom that is not very "soundproof" and the guests are often hesitant to use it.
Came up in a discussion in an electronics forum, never knew they existed until now. The rest of the discussion contained useful hints like playing either Handel's Water Music or the 1812 Overture finale depending on what activities were taking place.

Wish these things had been around years ago.
