Is there output delay on aux input? (Soundcore Motion+)

Hello, I want to buy a Soundcore Motion+ for DJing and use it as output for my XDJ-RX2 controller. Since I would control music in real-time, the output needs to be instant (no delay whatsoever). If I connect the Motion+ via an aux cable, will there be a delay?

Never noticed one myself when using with various devices but everyone’s hearing is different (ie by very small milliseconds)…

There shouldn’t be since it’s not a wireless connection
