Charged is the headset within about 2 hours.
With a "charge" can be heard for about 18 hours of music.
The Bluetooth connection was performed in all my devices quickly and easily.
Connected I have the headphones with an iMac, with my HTC and my Hisense.
My ear size I call "normal."
The comfort of these headphones I find very pleasant,
my ears are completely surrounded by the soft leather upholstery.
I can wear these headphones for hours to feel no pressure points.
Striking is that the ears be warm after about 30 minutes, without having a schwitziges feeling.
The sound is impeccable, treble, mid, bass are very well reproduced in balance.
Also, you can answer incoming calls by pressing a button, the music is interrupted.
