Add Logitech H390 headset to example list

Why is this change being made?

Add an example headset (headphone with mic) to the list of example equipment. There was only headphones with no mics in the example list.

This headset is what I use day-to-day for the last 4 years with no issues.

This addition is also below the reimbursable limit of USD $100 for "Headphones (wired or wireless, with mic ability)"
