I purchased an open box product and need an owners manual on how to make headphone work. it's a wireless Hi-Fi Stero sound M-HW160 model. Is that something I can get online? Or can you please email one to me at vcbosco60@gmail.com. Headphone dosent turn on or reset at all does it require a battery or some kind of special setting ? Again head set has no power. Thank you V C Bosco
