So far I have used the box at home and in the car. At home you can walk around with it and so did his music at all times. However, the radius is limited to a few meters, which is why, of course, not always get there so in a big house. I currently have a small apartment, which eliminates this problem and I can walk around with it everywhere and the quality does not suffer. In the car I've tested it for fun and in combination with my phone and lo and behold, the box is loud enough and the quality is sufficient to my 0815 investment in car almost zoom. Since I have no way to connect my phone to my car, on my phone but otherwise have a lot of music and hear the way with the box in the car has become a real alternative!
All in all, this box highly recommended for people who are often on the road or anywhere want to have their music while at her home.
