No noise for me, very very quiet

Hello.
Yes, a friendly lady's voice says it's connected. It doesn't bother me. You just have to turn down the volume or something. The battery is good and lasts a few hours. I use it in my older Hi-Fi systems and battery boxes as an extension. Greetings Christoph

Doesn't make a sound with me.

Hello
I have several of these in use and they make noises when they are re-coupled. So a triad and a voice connected says, pretty much the same as the Logitech, but the sound is better than the Logitech (definitely more headroom).
Greetings Thomas

Hello
No it doesn't. So far I am very satisfied with the article.
