My 3-year-old Google Pixel 4a phone has a headphone jack. That was one of the reasons why I bought it, so there’s no need to retire the excellent and durable Sony portable headphones that I bought at least a year before starting this blog.
Whenever I eventually get a new phone, it will undoubtedly not have a headphone jack. Adapters with a DAC that converts USB-C to 3.5mm analog audio can be had for $10 and less.
Another option is the Linsoul 7HZ Salnotes Zero IEM with USB-C connector and built-in DAC. It costs $24 and works well, with volume and play/pause controls for mobile use.
Used with the right ear tip (for me it’s not the one that’s pictured) the sound is excellent. For the ultra-nerdy, there’s a setting in the Wavelet app for Android that tweaks the sound closer to the Harman IEM curve.
