I think it depends on what you want - I have some pricier headphones myself & I used to own monitor speakers too, but I never think to use any of it with a phone. I use a phone to be on the go, and having big headphones don't go with that well unless I'm sitting for a long time like an airplane.
So far I've been dealing with being on the go with the PowerBeats Pro - it's good enough for my purposes (light, good battery life, sound is good enough, somewhat compact), although I have it mainly because the AirPod Pros were not out then.
