There are lots of uses for cordless microphones. They’re handy for MC’s, DJ’s, singers, performers and public speakers of all types. But whether you’re looking for a cordless headset microphone to teach a yoga class or a really top-shelf cordless karaoke microphone there are some important factors to consider.

• Frequency Range: The whole point of a cordless microphone is freedom; so knowing exactly how far you can travel without signal loss is essential.
• Frequency Type: UHF, VHF or Gigahertz?
• UHF: Fixed frequency UHF is the choice of most professionals.
• VHF: This is cheaper and works just fine in most situations.
• Gigahertz: The digital frequency used most often in phones.
• Pick-up Pattern: Cardioid Microphones are directional, and block sound from the rear (and sided in a super-cardioids), while omni-directionals pick up all sides.
• Type: Traditional hand held microphones are the most reliable and versatile, but when hands-free is a necessity there are headsets and clip-on (lavaliere) models.
• Batteries: Light, long-lasting batteries are the ideal (at least 10 hours); it’s always handy to have a battery level indicator as well.
