This article is mainly to discuss the difference between a wireless microphone and a Bluetooth wireless microphone. 

The main difference between a wireless microphone and a Bluetooth microphone lies on 2 points: 

1. interference 

2. The way of receive signal

What is a Wireless microphones?

Wireless microphones include FM wireless microphones, VHF wireless microphones, UHF wireless microphones, Bluetooth wireless microphones, etc.

What is a Bluetooth microphone Speaker?
The Bluetooth microphone uses Bluetooth technology to achieve voice signal conversion. Also, Bluetooth microphone is a kind of wireless microphone.

Wireless microphone Vs Bluetooth microphone speaker: 

I. Signal interferences are different

a. Wireless microphone: Due to the high frequency of wireless microphone, electrical interference from clutter is greatly reduced.

b. Bluetooth microphone Speaker: Bluetooth microphone has low frequency and is susceptible to interference from various electronic clutter.

II: Different signal reception:

a. Wireless microphone: The wireless microphone can receive voice signals of different working frequencies from each pocket transmitter at the same time.

b. Bluetooth microphone Speaker: The Bluetooth microphone can only receive voice signals of the same working frequency from the pocket transmitter.

III: Different functional links:

a. Wireless microphone, that is to say, a microphone without a cable, with external sound effects, and cannot be connected to a mobile phone:

b. Bluetooth wireless microphone Speaker, the selling point is the Bluetooth function, which can be connected to mobile phones and various music apps.

Precautions for using the microphone:

1. You should adjust the volume control of the speaker or mixer to the minimum, then connect the phantom power supply to the microphone. Then turn on the power switch of the phantom power supply, and adjust the volume slowly from low to high. This is because we need to avoid the speaker receives a big impact. Try not to make the microphone and the speaker face each other and keep a certain distance between the speakers.

2. The microphone is very fragile when recording. You have to be careful not to drop it from a high place or give it a strong impact. Pay special attention not to overturn the microphone holder when the wire is pulled. Too much impact may reduce the sensitivity of the recording function or even damage the microphone. 

3. When the microphone is not in use, it should be stored in a dry and clean place. Keep a suitable temperature and humidity is very important to protect the microphone. If the temperature is too high, it will hurt sensitivity and tone of the microphone. The recording diaphragm will accelerate the corrosion of the metal material due to water, and it will cause short circuit of internal circuit wires as well.

4. The best distance while recording is between 20 and 50 cm. Too close to the recording microphone is prone to phenomena such as spraying and popping. It is advisable to add a spray cover between the recording microphone.
