Hands free microphone
Required a good quality microphone that didn't need to be hand held. It's very lightweight ,nice and loud and importantly its very clear for voice amplification over a pa system. Once attached to over the ear there are no annoying wires or cables to worry about. The voice is received by the small plug in received you insert into the pa system. Doesn't loose what spoken like a lapel microphone when you turn your head sideways. Excellent value for such a superb hand free microphone. Delighted with my purchase which I use at weddings and burial ceremonies.

Works well but cuts out after not speaking for a few seconds and when you start speaking again it doesn't catch your first word.

BRILLIANT WIRELESS MIKE
Remarkably versatile little gadget. Good speech & singing quality considering the price. Very good pop/wind shield. Not sure about the quoted Bluetooth range though.

Doesn't like heat or sweat 💦
If you get hot and sweat while instructing a class this is not the one for you! Heat and sweat make the mic cut out! I've had to but a differant type for my hiit and sweaty classes. Apart from that it's a good mic, easy to use plug and play.thou the head band is not tight enough and falls off my head when doing burpees etc.

Sound clear and easy to use. Fits comfortably on the head
I’ve been making public announcements at evens that I have been organising. It works easily. I was worried maybe you need a technician but it’s was as pie. You have plug in the wireless attachment in the Aux and that’s it connect to headset which is similar to what you see on tv. It clear and the sound comes out Clear over the speaks. It fits nicely on my head. It’s flexible so makes it easy to place. The battery life is pretty good I have charged it twice so far. I’m impressed overall.

Has Many uses, not bad quality.
Wireless Microphone comes with a microphone, removable ear hook, Signal reciever, USB Charger, 6.35mm cable and user manual. I's really good for the price i'd say. The build quality feels really good, not bad at all! Very strong. has a shiny finish! The audio quality sounds fine, not really too bad at all. Great for skype calls. Really like this product. Works fine for me :) Quality is good and the microphone can be handheld or on the head..
