However, your argument about reducing environmental waste is flawed. AirPod, in total, weigh less and use far less plastic than your design.

Given the scale of production, the raw material to final product path will be short and relatively low impact. Your process involves much more packaging, transport and middle-man costs.

Feature set wise, your design is also significantly less.

I'm very supportive of people making product that is better suited to them, but the idea of this approach being somehow less wasteful is completely ridiculous.
