Audio microphones provide sound capability for musicians and personal computers in a wide range of multimedia applications. Whether they're computer microphones or those made especially for recording, their basic function is to convert sound into an electrical current. A wireless microphone, or one that connects via a USB port, works the same as a standard wired microphone but makes setup easier.

Whatever the application, buy microphones that have a dynamic polar power, or high sensitivity, that will pick up and then emit the widest range of sound frequencies. If you run a recording studio, you'll also want to look for microphones with low inherent noise to drown out any background sounds.

There are thousands of sites to help you in your microphone purchase, but make sure you get:

1. Microphones for specific applications

2. Reviews from users

3. Price comparisons

Action Steps
The best contacts and resources to help you get it done

Decide what type of microphone will best serve your needs

Musicians need microphones specifically for recording and live performances, while those who run customer service help desks often rely on wireless microphones or traditional computer microphones for live web chats. Turn to specialized sites for specialized equipment.

I recommend: For the best in studio recording microphones, go to InstrumentPro. For the widest range of both traditional and wireless microphones, including its highest-ranked headset for office use, browse the selection at Headsets.com.

Browse reviews for user-friendly microphones

Loyalty to a certain brand can aid in your decision, whether buying a microphone for computer use, audio microphones or microphone equipment, especially if you know you can rely on the brand's customer service. Reviews can lead you to products with the right customer service for first-time shoppers and will also let you know that just because you buy microphones with a high price, you aren't always getting the best quality.

I recommend: Microphonereviews.com and CNET can start your search for the right choice in microphones based on what others are saying about specific models.

Purchase microphones and microphone equipment online for the best price

Finding the lowest price is the bottom line in shopping for microphones. You'll find that prices vary from website to website even when you're looking at the same make and model. Go to local retailers to shop for microphones and forget about paying shipping costs. Keep in mind that there is a slew of online companies offering free shipping and rebates as incentives.

I recommend: Check out frequently updated specials and discounts on both microphones and required software at Microphones.com. Shop Music 123 for microphones and microphone accessories and get free shipping on orders of more than $99.
