Noise Reduction EarBud Headphones

Poor mans noise reduction ear-buds. Many advantages over ($200-$300)Bose: cheaper (pennies on the dollar) and smaller, allows mobility, no batteries required. Using existing (JVC) noise canceling Ear-buds, use Flents (or other manufacturers) spongy-type earplugs in place of the JVC plug. If you have heat-shrink, you can replace and elongate the JVC tube to allow inserting the Flent's plug better into your ear.
Great for planes, bus/car, mowing the grass, loud work environment, etc. Your mp3 player will only require 1/2 volume with these - thereby extending battery life.
Also - See my short 'Video Instructable' for the very same thing.

Get some earbuds similar to those shown.

Pull the blue cushion off the earbuds - this'll be replaced using regular foamy-type earplugs.

If you have some heat-shrink, you can make the tube long thereby using more of the foamy-type earplug. If no heat-shrink, cut to length just exceeding the earbud tube. If the plug is too long, it will squeeze shut where the sound must travel through.

If you have some heat-shrink, cut to desired length and shrink around existing earbud tube. A longer tube allows more use of the earplug thereby eliminating more external noise.

You must punch a hole thru the earplug, in order to pull it over-top the heat-shrink (or earbud tube). Get a cheap hole punch kit from any hobby store. Squish the earplug into a pancake, place the hole punch on center, strike once with light hammer. Allow earplugs to expand.

Once the foam has expanded and the hole is thru the middle. Pull the plug over-top the heat-shrink tube. It should fit snuggly so as to not slip off. Some trial and error may be required using different size holes.

Squeeze the plug to compress foam and slide into ear canal. Plug into mp3 player and Enjoy.
