yes, there is a mute button below the power button on the microphone side. I have not used it, as I've just hit mute on the video conferencing app, so I can't give any information about how well it works.
Hello Nick, unfortunately no, you cannot use the USB dongle from the mouse for this headset. Only our compatible mice and keyboards work with our Unifying receiver. -Danielle from Logitech
Hi Emjay, If you're talking about online conference calls on your computer, then most assuredly you can use the H600 Wireless Headset to listen and talk in these meetings. As long as this is plugged in to the device that you're using for the online meeting, then you should be good to go to listen and to talk. - Richard from Logitech
Hello, the H600 features a USB dongle for wireless connectivity. It does not have or rely on bluetooth connection. The dongle allows for a one-to-one connection with your headset providing crisp and clear audio.
Hello. I am not familiar with an AID device, so I can't comment on the compatibility with that, but I can tell you that the H600 does not have a button to end calls on-board. The buttons on-board are: Volume up/ Volume down, Mute, and Power.
