When I record sounds with my headphones plugged in, the volume of record is very low. It's okay with no headphones or Apple EarPods - much louder. It was also ok when I used my iPad mini (with any headphones the volume of recording was the same as no headphones). Then I bought iPad 3 and this problem occurred. Have a look at the screenshot: the 1st sample was recorded with headphones (not EarPods) and 2nd was with no headphones at all. Help me please.
