They remain on if you simply take them out of your ear. When you take them out and place them in the charging case, they turn off and begin charging.

Why are my wireless headphones flashing red and blue?

They are in pairing or discovery mode. This means your headphones are looking for another Bluetooth device to connect with. Sometimes, headphones in pairing mode are trying but failing to connect with another device. They’re running into an error during pairing, so they blink red and blue to let you know.
