Works great!
I’m a guide in a sprinter van with 14 guests. This works great! Simple, travels well! Just charge it each night to assure I don’t run out of power!

Good for the money
Excellent product for the money. After taking it apart I found it uses a very long antenna that travels the length of the wire support. This improves the distance it will transmit. The wire support is very stiff. This could make it difficult to bend for fitting larger or smaller heads.

Gets job done
This functional and affordable piece is a life saver for working as an Interpreter. I pair it to multiple transmiters and it allows me to convey the message being sent to different parties, yet, staying at a comfortable distance without having to be loud. I love it!

Saved my tour
When the microphone died on the motor coach, I thought it would ruin the tour, but the driver had this as a back-up. We tuned the FM radio to an unused channel, tuned the microphone to that channel, and I continued with the tour. The sound was clear on the bus’s speakers and I was able to speak in a normal manner without straining. I have posted photos of the product on the tour guide Facebook page. It save my tour & my voice!

Don't bother with this product
This transmitter is not powerful enough to provide a clear signal even when standing next to it. I am a interpreter and use FM transmitters and receivers for a better quality. I have to replace the equipment I have since I can't find it anymore and the batteries died. I thought this would be perfect since I wouldn't have to carry the transmitter and only the headset. The equipment sounds great but, certain movements, like moving your arm or your head will cause interference even when only a couple of feet away, so you can imagine how bad it gets after 10 feet. If the reception wasn't so bad and staticky it would be great. Oh, and it could use a mute button. I'm returning it and trying something else.
