(I'm posting this for a friend)...

"I purchased a new VocoPro VHF-3300 wireless mics.

Would like to connect it to my stereo system to to have a faux karaoke for our living room so that mu wife and I can practice a little singing together.

The problem is of course the mics have 1/4” male plug and the stereo system has 1/8” female plugs.
