Bluetooth is handy as I professionally often have conference calls and can hide them by using the headphone the Umwelztgeräusche.
You have to press and hold the button, I thought at first would not work Bluetooth.
The sound is good. Above all, the ear cups and the carriers are well padded, which also allows extended wear.
The price-performance ratio is also to my mind in order.
I can only recommend the headphones.
