Are Google one of the last holdouts ?

I've been on cheap Android phones and just moved from Samsung to Motorola and both have headphones sockets.

No, the Pixel dropped the headphone jack ages ago. It's why I don't have a Pixel any more.

For my recent middle class Android phone, I got a USB-C dongle that I keep in my wallet since phones with headphone jacks have moved to the lowest end of the market and almost disappeared entirely. Doesn't seem worth it anymore.

The dongle is tiny and seems to be of good mechanical quality.
