Maybe you can check horsecom? It's for rider and horse 😁
Get an arm band that u can put your phone in, runners use them, you can play your music out loud. I found mine at the dollar store !
I don't use headphones I just play music on my phone and put my phone in my pocket when I am alone. If there are people in the ring I use 1 earbud.
I hack with only one earphone in! I don't feel safe with two as I can't hear for traffic. If the leads are away I think it's safe?
