Very strong sound. The microphone and amplifier = zero. It is made for the media in the car's engine. Do not screw it in.

The horns are very good but the microphone seems to be non-existent. For its price, quite good.

The only negative thing is that the sound is very weak.

So if you are a gypsy and you want to wake up the neighborhood on Sunday morning, get another one. The sirens are loud

For the money, it is excellent. Very powerful and with relatively good build quality. Now, it is too early to have an opinion on its lifespan as I have been using it for less than a month.

Good and powerful Chinese!! The microphone doesn't have a high volume when speaking, but the sirens break drums. Worth the purchase.

Very powerful. I didn't expect it, it pleasantly surprised me. The microphone with the buttons is of poor quality, but it's fine for this price
