After many weeks of keeping an eye out for an Airpods Max deal I ended up finally get WH-1000XM4. Why, first and second they are a ton cheaper ($200 vs $$380+) than the Max, then also lighter + more comfortable, better case and built in 3.5” jack.
My main concern is battery life on a “new" headphone that could've possibly been made 5 years ago.
Because I can never leave well enough alone I also picked up the Cambridge P100s to compare. Crazy long battery life that is user replaceable. USB-C audio support + charging at the same time. Noticeably longer BT range. Transparency mode seems better for voices. Heavier, the headband is less comfortable and the clamping pressure is uncomfortable in a different way. Doesn't fold.
According to most reviews they sound better than the XM4, but still playing with both.
