This is my current headphone setup. I still use my m50x with a BTR3, as my large headphones. And I have also gotten a pair of PLANTRONICS Backbeat Fit 3200. The Plantronics replaced my aging AirPods. I use the m50x when I'm working or communting. And I use the Plantronics when I'm out running or walking; and usually when listening to something on one ear when I walk around in the house.
