Isotunes earbuds - ISOtunes Sport ADVANCE BT Tactical Earbuds with Bluetooth, 26 NRR

Nice idea. But they don't fit and don't work. When i turn them on they make this loud, noise that almost blew my eardrums out. I was attempting to protect my hearing. Not make it worse by damaging my ear drums. They also make the same loud noise when turning them off. I was exited to be able to get a better line of sight with earbuds intead of earphones. I just tried to return them and OP will not accept these returns. I wonder why? Now I have a $120 paper weight. Do not buy these. These ISOtunes earbuds are absolute trash. Don't waist your money!
