I have purchased fun i7s wireless bluetooth 4.1 earpods from true gadgets online. There was no user manual given along with the product to understand the operation of the gadget. Further now while checking one of the earpod is not showing any lights while pressing the button, and not working, while the other one earpod is working ok.
