I bought Bose soundsport free truly wireless today from Amazon.
After using them for lease than 1 hour in gym my left ear bud started blinking red while right eat bud blinked white. So I put right earbud in charging case to see left earbud and left earbud showed red blinking light.
Does this mean that my left earbud lost battery in less than 1 hour while right earbud is working fine?
When I put the left earbud back it charged for only 10 minutes though it is indicating needs charging?
