I have a USB Plantronics I use, it's a bit pricey because of the built-in sound card, but it's great quality input & output. I use it for gaming. I've had a bad experience overall with Logitech headsets. The last two I've had, the microphone stopped functioning properly. Part of it I believe is poor design; it feels flimsy. The main thing you probably want is comfort. If you're just going to use it for dictating, perhaps a mono headset is all you need. And as someone who worked as a scribe for a dictation service company, I feel for them

That job made me want to rip my ears off and dip my head in acid. I'd say about 95% of the jobs were from financial advisors, and 80% of those were poorly, poorly dictated. You had people driving, eating, low-talkers, and some who just shouldn't be allowed to speak over a phone. Glad I got out of that hell hole
