Same, 770 pro 80-ohm from Custom Cans. I immediately recognised the removable headband padding.

Is that a Beyerdynamic headphone I see? Possibly an 80-ohm version?

Americans will do anything to avoid just using trains.

Wasted Rick Roll opportunity.

The main problem was that it interrupted the line. We’d have to stop and inspect each product, then reposition or replace the connectors, before the reflow oven. It also ran the risk of damaging the connector, the PCB, or even the inserter head if the insertion force was too high. We had a higher rework and scrap rate compared to similar SMD-only products, but using pin in paste meant that wave soldering could be skipped altogether, and I guess someone above my pay grade determined that it was better in terms of finances.

This is just my own experience. I don’t know Rpi manufacturing practices.

I used to work on an SMT line, and pin in paste was the bane of my fucking existence. The parts (mainly connectors) were rarely within tolerance, and a leg or two would consistently miss their holes, if not outright rejected by the inserter.
