Quiza mi unica observación es que en el anillo de caucho o plástico del "fast charging", se acumula polvo por algun motivo. Audio perfectly synced, sound quality not perfect but more than enough. They are perfect for relaxing on the beach or just chilling at home listening to the Word or other relaxing sounds. This is my third mouse, the first two being the G502 Hero. Audio quality:Audio quality was better than I thought, but in hindsight, Im not sure I think that anymore considering the price. They?re also true to size. Let alone trying to pause using my hand. I still prefer Sketchers sandals to Chacos. Yep, that?s right - if your phone has got NFC capabilities, you can pair it to these headphones by simply tapping it against them, which is super cool, really convenient and works a treat.
