The week of the fourth of July is all about celebrating freedom in the United States. This year, however, I was able to celebrate in a unique way, with Logitech's FreePulse Wireless headphones. The headphones are meant to be used on the road in conjuction with an MP3 player or other portable device. However, they can also be used with any computer or other audio player, as long as a quarter inch headphone jack is present. These headphones boast that they are lightweight, comfortable and of course, wireless. Will these headphones let freedom ring?
