To start my new karaoke system, I decided to go with wired microphones, rather than wireless. Wired microphones are less expensive, and are more stable. Wireless microphones are subject to interference from devices using the same frequency, and also always seem to run out of battery charge when you least want them to. I may add some wireless microphones later, but I think it is a good idea to keep some wired ones on hand during every show in case your wireless ones have an issue. I opted for some inexpensive Behringer microphones that have a great sound. Keep in mind that these do not come with a cable, so you will need to buy a microphone cable for them separately.
