Amateur tinkerer Ian Anderson works in a wood shop and wears earphones to protect from the constant exposure to loud noises. To add a little music to his day, Anderson considered buying a set of noise-canceling headphones before committing to make a better pair himself.
Anderson started with a pair of Koss KSC75 clip-on style titanium stereophones that feature the same 60-ohm drivers found on the highly regarded Koss Porta-Pro model.
He embedded the KSC75s into a pair of Peltor 105 Professional Noise Cancelling Earmuffs using the tools in his garage and came up with a 3.5mm-compatible stereo surround headphone that also drowns out the noise in the shop.
With a combined cost of $40 for both headphones ($20 each), the DIY project ended up costing less than even the cheapest set of WorkTunes cans.
