Hardware prototyping consultant Ken Pillonel's latest project is to replace the Lightning port of AirPods Max with USB-C, which is part of his ongoing efforts to highlight repairability and sustainability issues in consumer electronics. The project comes in response to some user dissatisfaction with high-end headphones continuing to rely on the Lightning port for charging, as most other Apple devices have switched to USB-C, and there are rumors that second-generation devices will eventually make the transition as well.
At the same time, it is also a feasible method to repair the damaged AirPods Max Lightning port, because the cost of replacing the Lightning port is high.
Pillonel has customized a replacement part for AirPods Max, allowing any tech-savvy AirPods Max owner to upgrade their headphones to a USB-C port themselves. The work involved a complex design and manufacturing process, including developing an open-source USB-C conversion circuit and a custom printed circuit board that fit perfectly without drilling or damaging any of the original components.
The replacement part is designed to fit on top of the existing circuit board, completely avoiding contact with any other components. The design also addresses potential durability issues, with a flexible section that relieves stress on the connector, extending the life of the kit.
Pillonel explored the possibility of audio passthrough via USB-C ports, but ultimately decided against it due to the cost and complexity of integrating Apple's proprietary technology.
It is rumored that the second-generation AirPods Max will be launched at the end of 2024. The main upgrade is to replace the Lightning port with a USB-C port. No other major changes are expected, which means the headphones will likely miss out on features like the H2 chip and adaptive audio, but there may be some new color options.
