The Moondrop MIAD 01 is one of the most distinctive Android devices of 2024 thus far. It has a 4.4mm headphone jack to go with the more conventional 3.5mm type. Furthermore, it seems it might be as appealing to teardown enthusiasts as well as audiophiles, and may, therefore, also be easier to repair than most modern smartphones.
They take up quite a lot of space (for a phone) that could otherwise be used for a larger battery. I’ll happily take a few hundred mAh of battery life over a headphone jack. I find bluetooth headphones much more comfortable to use anyway. But I understand that some people prefer wired headphones.
