### ⭐⭐⭐⭐ Placement issue
*by P***A on 22 May 2025*

Why is the speaker wobbly? It makes me really irritating. But other than that it is a very fine speaker. The sound is amazing, battery backup is awesome, instantly connects via Bluetooth. No doubt about it, that's why I bought it. But this wobbly thing is making me pull my hair
