First off, I learned that I respond well to color being used in a diagram vs a letter or number to point out parts. I think I will use that from now on and show my kid.
Onto the product, not only am I extremely fond of the word torus and shape the of a torus, but I think I is very cool how this IE(o) has been adapted to improve the bass via repositioning of the sound generated torus. Most open ear I have tried ends up flat with too much in the higher end. This sounds exciting.
This tear down series is really cool. This particular post made me join the community. Can’t wait to see what else shows up.
