Sell things in the market, before buying a 20W output power amplifier, playing the song's voice is quite large, but it is not to use the headset. Want to know how much power amplifiers I can use to make my voice heard by people within 10 meters? Is 25W or 30W enough?
Of course, power is better, but also with your mouth and microphone distance has a very big relationship, that is what you say can sing, cause small voice.
The 20W on the market doesn't actually have that power. To use the headset to speak is not good, it is a problem of sensitivity. Sound quality is big, wired, you can consider winning E8M this. It works very well and supports the U disk. Wireless, power is 35 W, E17 is good. But in comparison, or E8M, perhaps for this environment, more applicable. May consider..
5W's tweeter, universal, and recording, so why bother?.
