The following did the job for me. Remember to change the headset to AD2P under SOUNDS in Ubuntu on your headset.

The "ambient noise" you're hearing is a loopback from your computer's mic coming out through your headphones.

This is apparently due to a bug with A2DP's implementation.

I fixed this in Ubuntu 19.04 by installing Blueman and pairing my headphones as an Audio Sink rather than a headset:

    Unpair your headphones, if they're currently paired.
    sudo apt install blueman
    Open Blueman, click on "search".
    Select your headphones, right click, select "Setup"
    Make sure they're paired as an Audio Sink rather than a Headset
    Select your headphones as an audio output in your sound settings

If you have Spotify open throughout the process you have to restart it.
