When microphone is activated, bluetooth headset speakers produce noise

I'm using an August EP 650, connected via Bluetooth dongle to my desktop PC running Windows 7.

The headphones work as intended. But as soon as I activate the microphone in windows settings (these settings ) it kills the sound coming from the headphone part of the headset. And by that I mean that they start producing this kind of noise

It's always the same type of noise and it only happens when I play audio to my headset. But the noises come at seemingly random intervals. It definitely doesn't resemble my music.

Using the complete headset (mic and headphones) works fine on my Samsung Galaxy S3 Mini.

How do I fix this? Any help is appreciated.

Right-click the little speaker button in your system tray, select "Recording Devices", select the microphone you're trying to use, and then click "Properties". Go to the "Listen" tab and uncheck "Listen to this device". Hope that will fix it.
