In this follow-up project, we see how to convert standard headphones into a crystal radio headset by swapping the magnetic speakers for piezoelectric elements. Good for low-power, high-efficiency listening. We use a 27mm piezo element on one side and compare it to a 20mm element on the other. We do thethe wiring, soldering, gluing, and sound test results across different frequencies. This DIY electronics hack is great for anyone experimenting with crystal radios, vintage-style audio projects, or custom headphone mods. Whether you’re into radio building, electronics tinkering, or life hacks for makers, this step-by-step guide will help you create a comfortable, efficient, and unique listening experience.
