I live in a small apartment and having family in the other room talking made meetings with clients really stressful. Literally my home had to be silent. Since I got these it really has saved me from embarrassing phone calls with kid screaming in the background or banging on my door during meetings. This headset literally blocked all that out. If your child is screaming or crying in the same area then it can pick up some of the back noise. My voice to callers sounded clear to them. I even banged on my desk during a test call and my coworker did not hear it. I spent a while researching different microphones and took a chance with Logitech. I am super happy with them. I wear glasses too which was not too bad with comfort. Highly recommended to those stressed out with home office background noise. ???Headphone ear pieces are not noise cancelling.
