AliExpress is fine, just use some common sense and look at the store that is selling the item.

When it comes to these Chifi IEM's, the likelihood that someone is going to waste their time trying to fake an imitation is very low. These things come out at a breakneck pace - there is a new one out almost every week. People who produce fakes are going to do so by creating fakes of brands like Sennheiser, not whatever new Chinese subsidiary of Linsoul that started producing IEM's a year ago.
