I use these headphones at work every day and they are the *only* pair I've found in the style I wanted: behind-the-head open-ear. They sound great, especially for the price, and it's easy to hear your surroundings while working, or exercising, or doing chores.
The volume doesn't go too high, but it doesn't need to, and the battery life lasts at least the course of a workday when at lower volumes (and charges with a USB-C cable). Any time I need to engage in a conversation with someone, I can reach up and pause the music with a press of my thumb on the right earpiece. I can also easily take them off my ears and conveniently rest them around my neck.
There are a few cons, but they aren't deal-breakers: there are no volume controls on the unit itself, so you'll need to adjust that using your phone. It would also be nice to be able to skip songs with the touch of a button on the headphones, but oh well. I love these headphones and I hope they keep making them forever, just in case I need another pair someday (but the build quality seems good, so don't worry!). Rock on!
