Review on 🎧 Etoput Auto-Scan Headphone Electronics with Soldering Capabilities by Leo Torres

I bought this unit as an educational project for adult students. The surface mount pads have been pre-tinned with lead-free solder. Great if you use that. Not great if you use lead solder, which my company does. It was still a fun project for them and has a good amount of SMT parts as well as a few through holes. The instructions were clearly written by someone with ESL barriers, but they were still clear and didn't interfere with the build process.
