Basically your battery is dead and needs to be replaced. I had the same issue with my Beats X in-ear headphones. My Beats X were also 5 years old and I hadn't used them in more than six months, which probably made things worse and allowed the Li-ion battery to discharge completely. I tried these options before confirming the battery was dead and needed to be replaced: (1) I charged my Beats X overnight for more than 12 hours. (2) I attempted a factory hard reset by plugging in the lightning cable to the charging port and then holding down the power button + volume down button at the same time, for 10 seconds or longer. There was NO LED flashing after the factory reset. I removed the lightning charging cable and holding down the power button didn't start up my Beats X. After plugging in the lightning charging cable, the LED would flash white/ red/ white/ red and then stay on white.
