This is how I made earphones from plywood. Very fast and easy project for beginners but it requires some special tools like lathe if you want a round shape for your headphone casing. Wooden headphones are a great way practice with leathe and it is and unique piece of accessory that will turn some heads. If you don't have a leathe and still want to make a pair of these awesome wooden heaphones, ask me and I will help you figure out way to do it.
