I bought this speaker system for my son to use with his iPhone. I live in a condo and I heart music with a low bass frequency. I thought it was my neighbor. I let it go for about 30 minutes. I decided to go upstairs and hear if it was loud coming through the wall and keeping him awake and to my surprise it was this mini speaker system so the next day I had to go and apologize to my neighbor for my son playing loud music.
