Thus, it is about 90 min. per day in use. So far I could nciht complain, quite the contrary.
The battery is charged only once every 1-2 weeks.
The transfer of music and radio plays smoothly. Even videos I shon converted with the enclosed tool and installed. Too bad, that the files are not thereby reduced.
The sound is very good and opposed Samsung here are very good headphones attached.
These are the first headphones, where I do not start your ears after some time to ache.
As a negative point, which is why the one star less, I see the on / off switch.
This is a bit shaky and attached to an impractical place.
PS: I specially chose a player with no touch screen, because you can use this even when wearing gloves. The winter this year gives me right. ;-)
