This review is after using the unit twice so far. I needed it for an online group job interview. Of the 16 candidates, it was my Logitechs and one other candidate that had the clearest sound and no issues connecting - (where the rest had trouble connecting, sounded awful, lots of feedback, or a glitchy few second gap as she spoke.) I'd hoped my Bluetooth headset (w/mic) would be sufficient but after hearing back a test sentance that I read aloud, I immediately began exploring other options. This wasn't the first Logitech headset I landed on. I decided to take a step up with this one to insure clear sound and quality microphone feed output. I'm sure glad I did. I got the job.
