You wouldn't need a headset. I've owned two Jabras and lost one, and the other one is "somewhere around my desk". Get a cheap one and see if you use it. If you do, then start thinking about a good one. Fry's has one on sale for 30 or 40 after rebate today, so there are some really cheap ones out there.

The Parrot will hook up to your empeg's aux in and has a mute line that can trigger the empeg switching to aux and back.

My prepurchase/review thread is here.
