The Sporta is what you expect from a headset. The sound is like the exellent expensive Porta. But Enscheident is the Sporta with larger and more expensive models can keep up in the sound. The reason for buying was ultimately the open design for me, since I do not just go use the Sporta but also at home, I wanted to be a model of the you do not get red ears as with closed models. That's the advantage of Sporta over other models. The guarantee of 10 years and the number of good reviews by specialized magazines were then the final confirmation of the purchase decision. Have fun with this ingenious part.
