Hello . I just bought a Z10 max pro but when I connect my headphones in bluetooth it is detected but the sound is inaudible.... like crackling. I tested with 2 different headphones....Sony MX1000 and Audeze phobius..as well as a bluetooth speaker. Identical results for all three. Permanent cracks. Has anyone had the same problem? Sorry for my bad English I speak French. The problem arises both on youtube and on MtvOnline2
