This is my Second time Doing this headphone project . I decided to create this instructable : in hopes of aiding anyone ; in way other guides might not.
Practicality of such a project varies , I will try to address a few circumstances. For me this project was ideal; being that i have Four pairs of headphone drivers ( speakers) that came from old broken headsets: each more expensive than the last. I rather have a little fun and save a few bucks, than buy some new ones. .

Step 1: Materials

You will need :
Drivers
- salvage them from a broken headset
- or sacrifice a working unit
- or Buy them individually (google shop search: Helment Speakers)
- or find subwoofers , mid range , and tweeter drivers small enough to fit into your contraption
(powering them might get tricky)
Earmuffs
- my first hack was with a set of red nascar earmuffs from a Big5 sporting good store.
they were on clearance at $4.99 i spent a little more on this project,
to achieve something more durable and with a nicer look.
- get your earmuffs from wherever you want , thrift stores are a great place
if saving money is an objective
Tools
- solder iron, solder wire,
- drill gun (i recommend a drill press if u can access one)
- electrical tape
- double sided tape
- wire cutters, wire strippers or a simple razor ( depends on your cable type)

Step 2: Getting Started

Disassembly required
- take everything apart
- desolder connections ( place some markings and take notes if necessary )
- note: left audio cable from right

Step 3:

-Drill holes
-Feed cable through holes ( leave some wiggle room)
-add a stopper (to the stopper) by taping around a spot on the cable,
otherwise you'll leave tension on the soldered spots
-solder things back together
- do some taping to clean things up if you like
- reassemble

enjoy

Warning: once you start listening to music at work ,home, or shooting range a functionality of
earmuffs that lets you hear people speaking , to a degree, is practically gone.
Be aware of your surroundings, and use them at appropriate times, like while practicing loud music,
at the shooting range, or ignoring a nag; although i wouldn't recommend that
because it tends to exacerbate the situation.

Step 4: I Made It at TechShop
