Reactive Audio Lights?

I make music for therapeutic reasons. I've found that immersive visualisations and lights help with this a lot. I've already bought a couple of rack-mount spectrum analysers and they are awesome.

Do you know of other devices that provide a similar visual experience? I know there are a bunch of cheap bouncing led bars on ali express and the likes but there is a problem: They work based on microphones. I need to be able to plug them in because I use headphones most of the time.

I know it is kind of niche but any pointers would be appreciated.
