The delivery was so after the friendly support was well taken care of me, arrived complete and packed well with me.
The package includes 4 headset microphones, battery powered with a 9V battery. a receiver including power cable and a connecting cable with micro plus "head wire." - all pretty easy and good portable.
I could build it quickly and without manual, although that has been available in German here. We have used the set for the first time at a book reading at a car dealership. We thought at first that did not come so many people and all of a sudden it was breaking full and we needed microphones. They sounded really good and there were no crashes, although the author and I, as well as the car homeowners constantly back and herliefen.
To make it short: This set is my absolute recommendation, especially if you also look at the price. Maybe I'll buy me even a hand mike to see. :-)
