Dohm/noise muffler/suggestions (11422)

Any therapists want to donate their old dohms?

Everyone is doing telehealth but I don’t have privacy at home and it’s too hot to keep doing therapy outside in the car. Old cellphone shuts off mid-session from the overheating battery.

Would really appreciate one of these so I can go back to having appointments indoors.

Also open to suggestions about alternative solutions
Thank you
