In the description it said that they were in perfect condition, but the first day the box did not charge more than 90%. On the second charge it did charge to 100%. The helmets after hours in the box charging, there are times when they do not charge. On the other hand they don't always connect to the Senheisser application... I'm trying to contact the seller following the steps you put on your website (my account, my orders and the red button) but I can't find the red button anywhere. On the other hand, your website is full of Buds and gives me error 500... I need you to give me a quick solution, it's my first purchase on the web and after spending almost 200€ on headphones in "perfect condition" I was expecting something else.
