The small headphones impressive with a beautiful design in combination with the white charging case. When removed, the pods already start connecting to the smartphone via Bluetooth. The connection is created quickly and also remains very stable. The sound quality is really great and you can turn up quite loud. The use of the headphones is also totally simple and easy to use. Thus, functions such as play/pause, quiet and louder, and also the song change can be easily achieved by a touch of the listener. Other functions are also included. These are all described in the attached instructions for use. A great product for entertainment. Particularly noteworthy here is the size of the case which is really kept very small and thus fits everywhere. I am very satisfied and enjoy the wide range of uses in sports when travelling or in other situations.
