1. Choose a microphone based on your usage and budget
Depending on your needs and purpose, users have different microphone options:
- For casual home karaoke entertainment without wanting to spend too much, consider a good-quality wired microphone. Avoid cheap wireless microphones as they tend to break quickly, resulting in unnecessary expenses.
- For professional karaoke singing, opt for high-end wireless microphones priced at $6 million or more for excellent sound quality that meets professional requirements.


3. Choosing the Right Microphone for Room Size
Before purchasing any microphone, consider the size of the room to select the most suitable one:
- If the room is spacious, opt for a wireless microphone for convenient mobility. However, keep in mind that microphones also have signal reception limits, so avoid moving too far, affecting the signal reception capability.
- In the case of a small room where the amplifier can be placed close to the microphone's position, choose a wired microphone to reduce the occurrence of interference when in use.

4. Choose to Purchase Microphones from Reputable, Well-Established Sources
In today's market, there are various types of microphones, making it challenging to select a high-quality one that suits both your purpose and budget. To ensure quality and a good warranty, it's advisable to buy microphones from reputable, well-known stores.
Some advantages of purchasing from reputable stores:
- Buying genuine, origin-verified products
- Long-term warranty policies
- Guidance from a professional and experienced team of staff
- Free delivery (depending on the product type)

5. Wired or Wireless Microphone: Which One to Choose?
In today's market, there are mainly two types of microphones available: wired and wireless. So, which one is the best, and which type of microphone should you choose?
- Wired Microphones: Wired microphones are suitable for small-sized rooms like cafes, small stages, etc.
- Pros: Easy to connect and use, excellent and authentic sound recording capability, high durability, stable signal transmission with minimal interference or signal loss. Users don't have to worry about battery interruptions, and the cost of wired microphones is reasonable, catering to a diverse range of customers.
- Cons: Limited flexibility due to the length of the connecting cable. The use of wired microphones may require additional adapter ports if the plug types are incompatible.
- Wireless Microphones: Wireless microphones are suitable for larger spaces such as large stages, outdoor events, and individuals with a need for frequent movement.
- Pros: Wireless microphones overcome the limitations of traditional wired ones. They are compact, convenient, and do not require cumbersome wires and connectors due to signal transmission via frequencies.
- Cons: Due to the wireless nature, signal stability may sometimes be an issue, and there is a common occurrence of interference during usage. Regular attention to charging or battery replacement is necessary, and the price of wireless microphones is generally higher than wired ones.

6. Important Considerations When Using a Microphone
First: Avoid placing microphones close together, as this proximity can create interference between them, leading to unstable sound waves and a noticeable decrease in audio quality.
Second: When using a wired microphone, if your hands are slightly numb, ground yourself with the amplifier. It's advisable to wear shoes or avoid direct contact between your feet and the ground.
Third: During use, refrain from holding the microphone head (microphone cap) as it can cause interference and impede the user's vocal performance.
Fourth: When using a wireless microphone, be cautious not to hold the end part of the microphone (antenna transmission part) as it may obstruct signal transmission, resulting in intermittent signal loss.
Fifth: For wired microphones, avoid holding the end part (the contact point between the plug jack and the microphone body) to prevent feedback and noise through the speaker.
Optimal microphone holding position: Hold the middle section of the microphone body.

7. Essential Quality Checks When Purchasing a Microphone
Ensuring the quality of a microphone requires a minimum of two different microphone sets for comparison.
- Step 1: Turn on the microphone with the volume set to medium across the entire system. If there is a booming sound through the speaker, it indicates that the receiver lacks an anti-interference circuit.
- Step 2: Sing half a song using one microphone and the other half with another microphone to compare the results.
- Step 3: Sing a phrase with microphone A, another phrase with microphone B for immediate comparison. Then, turn off the music, only activate the microphones, and sing continuously to see which microphone produces the sound that suits you better.
A good microphone will have a wide and accurate sound range. A quality microphone is one that can adjust both bass and treble very high, and the high-pitched sound can be comfortably adjusted without distortion.
Note when testing at the store: If you are buying a wireless microphone, hold the microphone and find an obstructed area to check if the product's receiver is strong enough. Sing a random song to test which microphone's sound is clearer, without distortion, warmer, and requires less effort while singing.
