That's very true. This small device I have made eights around 6 gramms and
the heaviest part is the cable + the 2x3 header:

I think it could have been made in a different way shrinking the PCB and
also if I were using the 0.8mm PCB instead and a light weight cable and
maybe one channel filtering only then the whole lot could have been half of
it easily, maybe even more. Also you can use different type of material for
PCB that coudl have different weight, like
