Squeaky noise coming from rear wheel on Honda Accord

I have a Honda Accord 2004. I hear some noise coming (presumably) from the left rear wheel. Here is a recording:

I’m not braking, the car is in neutral and it’s just rolling down a hill. (I’m braking at the end of video though to stop the car.)

The noise goes away after driving around for a while (or at least it gets quieter and I don’t hear it). The rear wheel bearings were replaced ca. 1 year ago.

What could be the issue?
