First thing i tried was connecting it to a different device... same problem. I've tried a S4, S3, S3 mini and a Note 10.1... all have that same problem. So first thing to conclude, there is something wrong with the headphones......
But then i tried an iPhone..... it worked fine :/
So it seems to be about the basic way android sends sound to the headphones.. anything i can do?
P.S. these headphones can be connected with a jack, in case it's out of battery. If I do so, sound sounds fine.
