I switch between Adam AX3 monitors and ATH 50x headphones. I also switch between my laptop and my iPad. Definitely the perceived differences in gain are different on headphones than on monitor speakers so I think it's a good idea go switch between the two often just to keep the ears tight.. Also, having the headphones on for a long period time is very agitating to me so I have to use the monitors quite often.

Que interesante observación, lo tomaré en cuenta, gracias.
