Wireless Mic or EasySing Mic for Partybox 320?

Decided to get a Partybox 320 to do mainly indoor karaoke with 5-10 friends. The 320 might be too much but I can get a used one cheaper than the 120 currently.

But I dont know about the mics since the EasySing seem to be rather new.

I will not need their AI features at all but I would like to own the better sounding ones. Any opinions on that?

Can I turn off the auto-pitch for the EasySing? I dont want our voices to be changed by AI. We sing just for fun.

Bonus question: Are there any other reasonable priced mics that would do the job even better?

Thanks!
