What's the best audio solution for me?

Hi folks,
Not sure what board this should go under, so I picked the closest. And apologies for the vague and indescript title.
My wife and I host 1-2 radio shows a week online and as much as I love my studio-quality microphone, the physicality of our situation makes it so that my wife often can't be heard and I may become too loud as I lean in towards the computer to read something or change something on the computer. So I think the best option is two headsets. I'm hoping someone out there might have a solution for my need.
I went to my favourite small-time computer hardware and repair store for a solution and was told I should just get two headsets and two audio splitter things (which weaken the signal). Then I went to Maplin and look for a solution off the shelf and saw these ridiculous things that came with one headset and one tie-clip microphone, which I will go for if I absolutely must.
My wife suggested I check online for a solution. Maybe there's a superior piece of hardware made for this very purpose. Yet I have no idea what to type into Google or which supplier to go to to find such a thing which I'm certain exists.

Any ideas?

Thanks guys :D
Happy New Year
