Query: Very uncomfortable; mic arm is in my field of vision

I didn't even try this to see how sound quality, etc, is because I cannot use it. The fit is not sufficiently adjustable. This is the older type of headset that goes over the top of the head. I thought I'd prefer this because I have long hair which often gets in the way of the around-the-back type. But with this thing sitting comfortably on my head, the lowest position the mic arm will go in puts it right in front of my nose, which is too much in my field of vision. This is (supposed to be) designed for use with a computer, so having the thing interfering with my view of the screen is very annoying. If I tilt the whole thing down a bit so as to get the mic out of my view a little, the whole thing just falls off my head. I think my head is pretty average in terms of size and shape, so I don't think this is just me. I'll be returning it.
