After a long day of meetings, Mark heads to the gym for a run. He puts in his F9-5C earphones, and they connect instantly to his phone. The IPX7 waterproofing keeps them safe from sweat. He uses the touch controls to skip to his favorite playlist. After his workout, he places the earbuds back in the charging case, which shows 70% battery on the LED display.
