I've been buying Logitech for almost 30 years. They're a regional employer and they used to make great products. This headset was my trying again to support Logitech. Instead it probably is the last of their products I'm ever going to buy.
Per this headset: The speakers and microphone were intolerably insufficient at their job. I chucked mine in the garbage. I didn't even bother returning it. I'm very disappointed.
I tried it on Windows 7 and Windows 10 machines. My audio was noisy (I couldn't hear what was being said) and my mic made me impossible to hear on the other end. This was a failure as a standalone set of earphones. It was a failure as a microphone. Logitech has really fallen off in quality over the last 20 years. I'm probably going to stop giving them "one last chance". I've been buying their products since the 1980s. They made great products that were a bit more expensive than the competition, but the quality and durability made their stuff worth the expense. Now even their more expensive offerings are bad.
