Sounds like FutureMe is exactly what you’re looking for.

Are there any keyboards on f-droid that offer word prediction?

I always go back to SwiftKey (but didn’t update if since they announced AI stuff) because nothing comes close, but I would gladly change it to something FOSS.

I tried to use it for reminders, like “remind me about the laundry in one hour”, only to realize a few hours later that I forgot about the laundry. The reminder never appeared. Asking “where is my reminder, google?” didn’t help.

I personally use two pairs that satisfy most of your criteria:

• Jabra Elite 85t. You switch between ANC/passthrough by double-clicking the right bud; it doesn’t need the app to do that. However, if your 12 h requirement is about consecutive hours, they won’t work (buds last about 5 h, plus 20 h from the case). They’re pretty compact and the case is magnetic, which I really like (coming from 65t model).
• Sony WH1000XM5. Insanely good ANC and nice battery life. There’s a physical button on the left cup to toggle between modes, which I believe are set to ANC/passthrough by default. The app lets you add a third mode (off), so you don’t need it at all.

I had a similar approach about headphones as you had - I only planned to use them for work, specifically Teams meetings in a loud office. But XM5s have such great ANC and sound quality that I now commute and travel with them.

For gaming, I’m using HyperX Cloud Alpha Wireless. They have an unbelievable 300 hours battery life and decent passive noise canceling, though no ANC. They’re using a proprietary wireless connection, making them fit for gaming without noticeable lags (Bluetooth sucks in this regard, I can’t play with 300 ms audio delay). Not sure if you can connect them to a phone.
