Logitech H390 Wired Headset

When I began teaching online the fall of 2018, I bought my first pair of these headphones. I taught every morning for 4 hours and Friday and Saturday night for 4 - 6 hours. So these were well used. Currently, my son is still using them.I bought a back up pair in early 2020 and they stayed in the package for another year before my son needed an emergency pair and I gave the old ones and wore the new ones.The mic arm on that pair has always been tight and awkward ... and sometimes it gets stuck and I have to wiggle the base a bit to get it to turn.So I wanted to upgrade and purchased two on the more expensive Logitech headsets .. that cover your entire ear.So, I'm nearly blind and rely on my sense of sound to compensate for what I cannot see. I was unprepared for the sense of unbalance with the full ear cover set. And I could not hear myself. And I had to keep reaching up to pull them away from my ears to let the air pressure equalize.I have one bright child, Anna, who only lasted 15 minutes with the new set before begging me to put on the old ones. (I can't hear you with that one .. it just sounds so different.) We also tried the bluetooth set, and said the same thing. I began asking my other students ... every one of them wanted me to use my old headphones. Although one said the bright color was "disturbing" after seeing the black ones for 3 years.With their urging, I bought a third pair of these. Not so comfortable at times, especially at the beginning, but they do loosen up over time.There is a volume / mute button on the cord that ONLY affects the volume ... and it is super easy to run my hand down the side to adjust volume with each student and to mute myself for a cough or to talk to my kids for a second.Some kids claim that they can hear everything going on around me, and others don't notice it. Only a few of my students use headphones or earbuds.I'm still teaching my same schedule here as 2023 progresses. And still wearing the same headphones.June 2024 ... I finally had to retire the last pair of headphones, as the wires were become exposed. So, a year and a half after purchase, I pulled the 3rd pair out of their box. And I wish I could send them back. These are nowhere near the quality of the last two pair. How disappointed I am! The size adjustments keep sliding out, so the ears sag as I'm teaching. The feel of the plastic is much cheaper. I can hear the slide of the plastic when I adjust the mic up or down. These are horrible - but I'm stuck with them. Also, there is a "burr" of plastic sticking out that scrapes my leg while I'm teaching .. on the mic adjustment. I'm not sure how long these will last, but it's not going to be the 3-4 years of the last two pair. These are horrible.
