"How do I fix my backbeat fit?"에 답변I got a pair for my birthday from my colleagues. Thanks to it I became a gym freak and lost some weight. My wife, seeing my weight loss, decided to get a pair for herself. Cost a lot of money for us in Malaysia. After using mine for 4 months, it no longer charges. My wife’s, after about 6 months, no longer turned on. This bad experience made me never to trust bluetooth head/earphones with irreplaceable batteries.
