"Building blocks" of the project
Step 1: After Adjusting Internal Size of the Case Proceed With Drilling Holes for Cables and Screws (in Order to Fix "head Wire")
Step 2: Added Acoustic Padding Approx. 3grams
Step 3: Prepare Head Wire. Made Sure That the Wire Matches the Hole (not Other Way Round)
Step 4: Test Before Measuring Before Closing Up.
Step 5: Gluing Ear Pads (to the Wood)
Step 6: Head Pad With Inner Cotton
If you want to make a pair for walking around better add a lot of head padding. Otherwise you will hear every step you take like a super heartbeat in the headset.
