Building a very small studio for very cheap

Hi everyone!

The heart of my first home studio will be a Korg microstation and a little laptop.

I plan to buy a pair Audio Technica m50x headphones for reference.

Question: I will receive two Jamo p404 active speakers for free. Are these any good? I know next to nothing about speakers. The only quality speakers I've listened to were Genelec, and I really was impressed by those.

If you have wisdom to part on a newcomer, please do.

Thanks for reading this!
