Maybe a bad switch.

Bought this to replace a mike on my wife's Karaoke machine that had issues with the on/off switch not turning off the mike.

The on /off switch is faulty

I love the on/off switch!

and you will see ... same issues every single time ... switch scratch, random mic muffle, cord shorts out and causes scratch

The switch broke two weeks after I bought the microphone.

When it was new the mic performed well but after about 6 months, the on/off switch became lose and when I touched the switch it made a lot of static noises

I like that it has an on/off switch

The third shipment is the worst ... the switch isnt the only problem this time ... touch the cable and your speakers will hum extremely loud and wont stop even if the mic is shut off
