I don't walk around with my boxes very often but I play them outside on a regular basis. I am often at the basketball court, park, or even in front of my house when washing my car I have a boombox with me. I always keep my red M70 in the back seat of the car in case I want to have lunch in the park and listen to music. I never leave home without a boombox...and I play them loud but not offensively loud. My usual outdoor boxes of choice are my M70's and M90...and I might add they are pure fun in public, most people get a kick out of seeing them and are surprised by the volume and good sound.
