3 angles stand for Anker SoundCore

This is the stand for [Anker SoundCore Speaker](https://www.anker.com/products/A3102011) that is popular on Amazon.
You can change a speaker angle, 30, 45, 60 degrees. Maybe 0 degree.
So the sound from the speaker is facing toward your face.

There are two types of the stand. One is a mass, another is a shell type.
The width is enough to push the power switch that plased top of the speaker.

Sorry I don't understand about sound quality this stand influenced.

Thanks!
