I work from my home office and make a lot of calls. I've tried using the earbud headset and it hurts my ears. It's too cumbersome to hold the phone all the time and speakerphone doesn't work the best for what I'm doing. Is there a nice over the head, monaural headset that works well? I'm fine with an office headset that needs an adapter two to work. Preferable something with volume control, mute and noise rejection. But I'll take what I can get. Any ideas would be great.
