Remember I used to have a truck?  And then I sold the truck, and tucked *most* of the money away, but also made a lot of impulse purchases?
I got 
these yellow headphones.
They are so so great.  With more consideration, I might not have picked yellow, but I still like them a lot.  And, AND, they came with a stereo-to-mono adapter (not that important to most people maybe, but for me?  Awesome surprise.)*
I also impulse bought some red white and blue 
sneakers.  I immediately wore them, and thought "what on earth! why isn't everyone wearing sneakers all-day every-day?  This is great!".  Then I realized I guess a lot of people 
are wearing sneakers all-day every-day - I'm just not one.  But now I'm a "sometimes, now I at least have the option" person.
Oh, and I got a Kindle. 
Yikes.
*other things that are great with these, aside from the adapter: 
  - folding (obv)
  - pause/play button on the cord
  - cloth cord, doesn't really tangle
  - there's a output hole, on the far side, that someone else could plug 
their headphones into, and then you could be listening to the same thing
