In addition, modern features such as multipoint mode, aptX HD codec, and the practical DAB+ radio function are used, resulting in a perfectly coherent package that is even suitable for outdoor use.”

A medium-sized speaker that you can "park" on a bookshelf, but which is made to take on the go

Teufel's BOOMSTER 4 is perfect for those who are looking for sound from a unique speaker that looks perfectly at home around your house, but is super easy to take out on the go.
Please check whether required cables are included.
