im from the US... i have an EF model... found under the ear cup... it is...HT-RSO-DIECBK13EF002099... But, with that said it worked perfectly before i left on my WIN 10 PC
how would i find the serial # as i have disposed of the packaging months ago... i have been out of town for a few months and when i started the PC today i seem to have the no device found issue even though the volume control appears to work on screen ... oh win 10
