First, you need to install Samsung Wearable to update and set the headphones. The app requires access to contacts, files, phone and photos! Why is access to photos needed for headphones ?! In addition, access to my site is required (even when not in use). If you refuse any of the above, the installation is canceled.
Second, the control interface is terrible. It is not intuitive and easy to print wrong.
In addition, the headphones cannot control the volume! Or yes, you can choose to control the volume with a long press or switch on the function for ambient sound. Thus, one must choose either to be able to control one or the other, not both and thus effectively exclude one of the functions.
And even if you choose volume control, the headphones CANNOT control the _ unit_ volume. Say if your phone is set to a low volume you cannot raise it through the headphones. Thus, the volume in the headphones and in your device is separated. Who does that ?! Any SEK 30 headphones can handle the volume of the phone. But not these Samsung's masterpieces. I wonder if Samsung's engineers even tested using their own headphones: - /
Wonder if you can leave the headphones back after trying them ...
