I'm writing a report on the QC 20 headphones for one of my tech classes on the manufacturing processes used in making the headphones. I'm curing what processes are used for the Stay Hear tips, as well as for the actual headphone itself. Thank you in advance for any help!

That's a great question. We do not publish proprietary technical data, however if you go HERE you can see what's available to the public. Click on your country, then search for the product you are interested in. The product manual and specifications should be there.
Hope that helped
