DIY headphones. How, and most importantly, why

I want to share my experience of listening to headphones and speakers, offer recommendations for improving the listening experience and tell how I came to homemade headphones and why I recommend it to everyone (sources included). For the construction, the tape technology of emitters was chosen and it is described why it is preferable to magnetoplanar.

It is necessary to somehow measure the characteristics of the resulting headphones, and this requires complex and expensive equipment in the form of a measuring stereo microphone and high-quality recording equipment. I don't have such equipment, everything was done "by ear", and the price bites.





Finally, a video demonstrating the work.

Added a video of the assembly diagram
