On a pedal bike, it's very important because you are most likely to be hit by cars from behind. Motorcycles move much faster, and most riders wear helmets as well, already impacting hearing. The road noise and wind is very loud, try rolling down the window in a car on the freeway and imagine that on .your whole body.
Had a close call with a cyclist going the same direction as me. She veered over in my direction as I was overtaking and was rather startled to see me, as she was wearing Airpods.

If anyone hasn’t tried a bike radar, they are a massive help.
Eg Garmin Varia. Take care with the new model, the light is insane, on 5% you have the eye of Sauron blinding the rider behind you.
