I was so happy to hear the sound from the cordless microphones after I hooked this system into my already existing home amplifier. Singing times are great with my kids. Great product for a little price !

These are a must-have with any Karaoke system. . .

HappyGrandmother February 21, 2017

After ordering the Akai Bluetooth Karaoke System for my grandchildren to enjoy, I knew that it would be in my best interest to order these cordless microphones. This way they don't get tangled into cords and fall through my breakables. Therefore, I am very happy with this online purchase through Walmart. Also, this item arrived in the same speedy manner that the karaoke system did, in 2 days! Walmart will definitely see me in the near future shopping through their online store website.

exelent unit for the price, the signal gets lost every now and then, but if you are like me just using it at home to have fun, this is a good unit.

Decent for the price

lucalexis September 5, 2016

It work just fine, perfect for occasional conference. You just have to practice to keep the same distance between your mouth and the mic to avoid the variation of the sound from the speaker. Go for it if you need a cheap wireless mic

works as intended, great price

bmf916 December 27, 2015

You get your moneys worth, they work as intended, they are all plastic and probably can break. just don't throw it across the room they will be fine. great reception from all over the house, only problem we had was feedback squeel (ouch) when the kids got too close to the amp speaker we were using

very unidirectional

wedding December 15, 2016

Microphones work great but you have to talk/sing at exactly the right angle which is tough to do.I ended up having to buy a corded microphone as a back up. Everyone at the party chose to use the corded microphone simply because it didn't matter how you held it or what angle the microphone was at.

Too little Information prior to buying item.

Melynwell October 30, 2013

Very disappointed with this wireless microphone system. What the description fails to tell you is that in order to actually use the microphones, you have to hook it up to an amplifier, receiver w/speakers, or a speaker that has the correct audio input. Had a very hard time trying to find an adapter for the 1/4" plug, since most stereo and other units have a 3.5mm input. Finally found one at Radio Shack for about $6. Still looking for an amplifier or something to hook it up to and find out if it works. Very, very disappointing. I should have just put my money straight into a karaoke system that has the microphones with it. Wouldn't recommend this to anyone unless they have the correct equipment to hook it to. Can't return it now because I stupidly threw out the receipt. (Also, one of the 9 volt batteries that was included was dead. Now I have to put more money into this thing to try to make it work.)

do not purchase. return window small.

michael July 22, 2021

horrible product. cheap price but does not work at all. kept getting radio static feed back. microphones would not co next to system. this seller has a shirt return window. 30days and I wasn't able to get into the building to see if thg is product was compatible with the sound system for our wedding. then couldn't make it back to Walmart to return in time because of distance. unfortunately out the cost of the product which is only $22 bucks but still is awful to throw away money on product that is total crude
