A: The red LED light will turn off once the ear bud is fully charged. It's normal that the other ear bud will charge longer than the other since they don't play the same frequency all the time.
A: No, they don't have SIRI built-in, however if you have an iPhone SIRI could be activated by holding down the Under Armour logo on the left ear piece for over 2 seconds.
Q: If using one side and the other is charging, can they be switched to keep talking?
A: Thanks for the question. You can use the right earbud of our UA True Wireless FLASH since it's the main/ primary bud that receives Bluetooth signals from a source device. It doesn't apply when using only the left earbud since it's dependent on the right bud. For more details, check out its Quick Start Guide here: https://bit.ly/2TIHgZi
A: They do have touch capability for volume, song change, and call answer.
A: Our UA True Wireless Flash X is not supported by our JBL Headphone App. You may try downloading third-party apps but we are not certain if it will be compatible with the UA True Wireless Flash X.
Q: Do these earbuds have a heart rate monitor?
A: Thanks for reaching out. Our UA True Wireless Sport Headphones doesn't feature a heart rate monitor.
