I would not buy these again! This was a good purchase for a six bottle wine rack and it is narrow which makes it a great space saver for small kitchen counters like mine. Per il numero io porto un 38 e ho preso il 38. Esto es algo que hacen algunas marcas como Bose 700 (Te dice las horas restantes de uso), Sony versión 3 y 4 (Te dice el porcentaje de batería restante de 10 en 10), o Jabra (Te dice si la batería es alta, media o baja). I will report back if there are any other long term issues when I use it as my daily headphones. Best of all, these shoes are true slip-ons. And Im glad I took the plunge, its exactly what I needed, peprfectly consistency paste, none-conductive and reduced my idle CPU temp (Ryzen 5 1600) from 44c Idle, to now 28c idle and 50-65c max when gaming. Tried these headphones while walking along moving train and close to a construction site - still can hear the sound without discomfort. Weightlifting, sure but running - no. I dont yet feel the lightness or the warm hues in the music put out by the earbud and at this price, honestly I shouldnt be expecting more.
