This concept is great, but it not matches the Nothing Signature.
Firstly the shape is more in Circular Side, that makes it look like Chi-Fi product. According to me its shape is in Rectangular side with curved edges, that make the product look more minimal & genuine, & fits in Nothing Signature.
& The Control Buttons should be on top side of the speaker, that makes it easy to operate.
One More thing, If the physical buttons are replaced by touch buttons, makes the speaker more premium.
