when i just got my beat upgraded a few months ago i was setting alarms from far away i thought it wasn't because of my beat but when i go to work i lower my beat about 150ft from getting there and i can hear many alarms, just today a guy from work told me i had good sound in my SUV, i was listening to music in the parking lot and he was sitting like 300ft at hes desk and had to come out and see what was making the bass and having everything vibrate in is office lol
