Review on Koss SB40 Computer Headset with Built-in Microphone by Anthony Grover

I bought two microphones for my kids to use in Zoom classes. I have paid SB45 USB for 4 years and they have been amazing. It was crap. The microphones never worked. I then returned within a week. Very disappointed. Now kids just use regular headphones from their iPhones via Bluetooth. Of course the SB45 that I had for 4 years broke after a few weeks and I therefore ordered a different brand.
