pin-drop

Used as an adjective to compliment something. Pin-drop's origin can be traced back to the common saying "pin drop silence"
When the silence is at its maximum, you can hear a pin drop.
It was later adapted to mean the ultimate/best form of something. It was popularised by music teachers from the 80s to compliment an amazing performance that led to a gobsmacked audience at the end of it.

That music performance was pin-drop worthy
The food here is pin-drop
Yo! Those sneakers are pin-drop
That's a pin-drop sky
