Se rompieron tras dos días de uso. - Excellent sound quality. Apparently its not uncommon and there are charging issues where it doesnt charge using the case for one or the other as Im finding. It took me a long time to find this reasonably priced headset. I live the feeling and the smell it has. I have been searching for a while now and these are the ones. It truly does sound amazing for the size and especially the price. Due to covid 19 not in a position to replace amazone shows it doesn?t know when the replaced product will be able to ship and they will email regarding that. Nice, comfortable simple slip on not really much else to say. Others were just a little too old fashioned.
