I used to have those headphones, but the mic on it was broken and I returned it. Other than that, it was a great pair of headphones, the sound quality was phenomenal.
On topic: Someone earlier posted something about online services, such as thumbnails, banners, intros, etc. I honestly think that would be a good place to start. Paint.net is a very simple, but effective photo editing tool if you don't want to purchase PhotoShop. There are certain plugins you can install to add more effects as well.
http://www.getpaint.netAnother good idea would be YouTube. It's really fun, and if you can manage to get partnered, you can make a little bit of money off it. Keep in mind it's very hard and frustrating work trying to get your channel to grow. Only do this if you enjoy doing it though. If you have no passion for making videos, it will show and you'll get nowhere.
Those are my ideas, good luck!
