Please forgive me while I nerd-out a moment here...

I've been using my homemade hi-fi headphones for a week or so and while they sound great, I really wanted to eliminate the cord going from the headphones to the iPhone/iPod in my pants pocket. It annoyingly gets caught on things around the shop and could be potentially dangerous as well; getting pulled into a machine and whatnot. The solution I came up with was to attach an iPod Shuffle to the rear of one of the cups via a short cord. The Shuffle is ridiculously small and lightweight and has a (quite frankly, awesome) VoiceOver navigation system that let's you sort through the iPod's content very effectively without the use of a screen. The end result is clean, lightweight and self contained. I'd like to send a great big "Thank you" to my brother and sister-in-law for their birthday gift card with which I purchased the shuffle. Thank you, guys.

Also, for those who were wondering, the last two pictures detail the Koss headphone speakers embedded within the ear cups. The speakers are held in place by two vertical slots cut into the sides of the red plastic of the ear cups which allow them to sit closer to the ear, providing better sound. I had to play around with the slot in order to get the headphones close enough to my ears to sound good, but not so close as to put undue pressure on them. They are pressed to the front of the slot by the existing ear cup foam behind them.
