An antero-posterior/lateral view of the AKG K518. Just as in the AP view, there is asymmetry of the folding mechanisms. The wires are also different between each earcup. Perhaps they are hastily put together. Prognosis is positive. Performed at 40kVp at 20mA and 1000ms.

An antero-posterier view of the AKG K518! Maybe slightly obliqued. I can't avoid beam divergence! Note how radiolucent most of the can is. It has so much plastic in its build! Sadly, I can't get plastic to show up well because I can only get my kilovoltage peak down to 40. For some reason, the folding mechanisms are asymmetrical. It could be due to beam divergence, or maybe the headband is twisted o.O. It reminds me of doing a lateral elbow exam! I wish I could get perfect blackness around the cans, but it would take a lot more milli-ampere seconds. I'll try different techniques next time! Performed at 40kVp at 20mA and 1000ms. 20mAs should be more than enough, right?

A crazy oblique view of the AKG K518. I put a "radiolucent" sponge between the earcups to hold the headband up. As you can see, the top headband is constructed out of steel! But everything else is plastic. That doesn't mean it lacks durability! The folding mechanism seems to operate using multiple steel rods that act as pivot points. I should get some radiographs of the cans folded to see how they work. Performed at 40kVp at 20mA at 1500ms.
