Evergreen Technologies is no new player in the computer industry. Based in Corvallis, Oregon, Evergreen pioneers a range of solutions that "refresh" older systems to current processor performance and functionality. It was founded in 1989, and manufactured its first product by 1990, a processor upgrade to replace a 286 with a 386SX.
Now, Evergreen has begun to branch out with their RumbleFX line of consumer electronics products. Today, we'll take a close look at their first product sporting the RumbleFX name, the RumbleFX force feedback headphones. Here's a brief technical overview of the headphones :
