Fairly quiet with a really nice retro key sound!! only complaint is that there’s a very subtle high pitched sound from the keyboard while powered on. Not an issue for me though as wearing headphones or earbuds completely blocks it out

It's an amazing keyboard

Quiet and exactly what I ordered

it makes amazing sounds it has no delay and it is easy to setup

I like it, it’s different from what I usually used and works very well and fast, have somethings that wasn’t that god but wasn’t take too much time to get habituated to it. And have a important thing, don’t exist in Portuguise or Spanish
