This really shows how tiny the components really are. One can only appreciate the extra mile you’re going to get it exactly like you feel it needs to be

Yeah iem/bud parts are TINY AF. Its horrible to work with BAs especially, they are small and lightweight enough that if you accidentally breath too hard or sneeze, they will fly away and dissapear lol.

Seeing them like this made me realise just now how you actually made a lot of alterations to the previous design in such a short period of time (since about April right?). That is impressive.

Yeah im at around 300 revisions since the beginning… also I had to learn Autocad Fusion 360 which was a bear.

Have you checked for springs at Digi-Key and Mouser?

I already got all the specific ones I needed. They are 4mm x 5.5mm, 6mm tall with a 0.3mm wire diameter. Perfect. Thanks though!

Very similar. my design had the tube venting into a sealed chamber rather than just a vent. Still I dont want a flat midshelf. It displeases me so I went the entirely opposite direction. Earbud in an IEM. No air seal anywhere.
