Wireless microphone for less than R$40; yes?

What I liked most

Easy to use. Compatible with smartphones that have USB-C input. If your cell phone is not compatible with this type of input, just purchase an adapter.

The setup process is straightforward: simply plug the receiver into your cell phone and turn on the microphone so the devices will connect automatically, without the need for additional apps or complicated configurations. Everything works via Bluetooth.

Lightweight and wirelessThe microphone’s lightweight and discreet shape makes it easy to attach to clothing. The absence of wires allows the user to move around easily, which helps with outdoor recordings, interviews, presentations, and video conferences.

Better sound quality than your cell phone’s internal microphone.It can reduce external interference, such as wind noise and background noise when used close to the mouth. I have shot several times with strong winds in Atero do Flamengo, Rio de Janeiro, and the sound was good, no noise or problems.

Signal rangeIt operates within a radius of up to 20 meters in areas free of obstacles, providing the user with the flexibility to move around without losing sound quality, according to the brand.
