The Teufel Airy Open TWS proved to be very flexible when tested. The angle between the headband and earpiece can be adjusted extensively. The sound is also clean and warm. What the Airy Open TWS lack is an app. However, the great touch operation on the open ears makes up for this shortcoming. Unfortunately, the running time of just under seven and a half hours is a little poor.
