the t.bone free solo HT 1.8 GHz

There are two significant disadvantages. The first - if you hold the microphone at the bottom, then a hissing sound appears until the signal disappears completely. I've had this happen several times when the speaker is holding the microphone on the underside. And the second - if you happen to keep the receiver outside, in the sun, it stops working after a while. It heats up pretty quickly and that's it. In identical conditions, Sennheiser microphones work flawlessly. Unfortunately, these radio microphones cannot be trusted. The heat would still be acceptable, but if the signal starts to disappear when holding the microphone at the bottom and the distance is not long, then it is serious.
