For the price it’s selling, Fifine K037B microphone offers a lot. It has way more pros than cons, and while it might not be the most suitable wireless microphone for professional recordings, it’s still pretty decent.

I’d recommend it to anyone who needs an easy solution to recording outside and wants to get rid of the cables.

When you’re in a situation where the wireless microphone would be a good fit, going for the hands-free microphone is even better.

Fifine K037B is a wireless microphone that offers hands-free service while providing a studio recording audio quality for many different purposes.

It goes without saying that Fifine K037B offers a lot of value for the price, so stay tuned and have a look.

Design and Build Quality

Fifine K037B consists of two transmitters and a microphone. The microphone is made to be in the type of a headset which allows the hands-free use, while it connects to the transmitter and through Bluetooth connection, it transmits the signal to another transmitter which receives it.

It’s featured in a black color which looks nice and professional. The headset microphone is very simple since it’s made out of a thing yet durable material for an easy use, yet without attracting too much of attention. Cable is also very thin and can easily be covered with a clothing for minimal visibility.

Transmitters are very lightweight and they’re comfortable, you won’t even feel that you have a transmitter on you.

Everything is made from a hard robust plastic material that completes everything and gives a premium feel with a sense of reliability.

The design is very minimalistic and there are only a few buttons on the transmitters such as ON/OFF button and frequency change button.

It’s most suitable for speeches, classroom teaching, conferences, interviews, and similar activities.

Audio Quality and Features

Fifine K037B is a cardioid microphone that transmits its signal through the UHF connection between the two transmitters.

The sound quality is great overall, and it’s very suitable for many events and occasions. It might not be considered as a professional microphone, but it’s definitely useful to have and is way better than standard built-in microphones.

Connection happens through the 1/4″ port, yet it can be connected to many various devices through 1/4″ to 3.5mm adapter.

I’ve tested Fifine K037B microphone outside, and one of the things that amazed me is how little background noise it picks up while walking outside.

Wireless connection between the transmitters happens through UHF and the best range you’d want to use this microphone would be in between 40-65 feet.

Batteries are replaceable and you will know when to replace there is a small LCD display that will show a warning.
