* Foldable and therefore space-saving portable, yet robust
* A storage bag is included
* Sufficiently variable size setting (I do not know what human head is not to fit in here!)
* The angle to the mouth is also adjustable: you do not blow into it, if you do not want, at Diktierpausen it can be folded away upwards
* The voice recognition works properly, better than with my previous device
* Sufficiently long cable to "to wander back and forth" before the desk
* The switch on the cable carrying clear understandable symbols for operation, more guidance than the also enclosed sketch does not need to
* Listening to music I have other headphones
