Hello.... I have this DZ09 smart watch.... It uses bluetooth 3.0 today i bought a wireless earphone to use with it... Firstly i checked another model of a earphone which worked fine with my smartwatch. It was LG HBS 800 Which had bluetooh 3.0 aswell.... But then i bought another model getting assured that yes my smartwatch supports bluetooth headphones, so i didnt check it on my smartwatch, just used it in my mobile and saw it was fine and bought it.... It was LG HBS 730 and in the box its written it has bluetooh 4.0 though when i researched in net it said it has 3.0...... I dunno whats the big deal, i just knew mostly all versions of bluetooh supports each others and i just needed to confirm if my smartwatch can pair with bluetooh headphone or not and yes it did with the 800 model and i even heard song but now it cant even find the 730 model.... What should i do!! Help me guys
