Review on Microphone Conference Recording Indicator Compatible by Brett Robinson

The unit was easy to set up but caused hum and noise when used with Apple products on the web. Not only that, it also interferes with every other device. During an active call, there was a complaint of a very noticeable hum. I turned down the input volume in Apple's sound settings, which helped, but then I couldn't be heard either. I switched to my regular internal Mac mic and found the same hum. When I unplugged the speaker, the hum was gone. I'm not sure what they did, but definitely don't use this on an Apple product.
