A:AnswerThank you for your question. You can use our JBL Headphones App to adjust the Active Noise Canceling (ANC) level on your JBL Tune Flex. However, please know that high-pitch noises can't be blocked out. The noise cancelling would only filter out every day environment noise. The feature on our earbuds isn't suited for extreme sound environments or professional settings that need noise cancelling. If you have more questions, please contact us.

A:AnswerPeople tell me that I sound like I'm talking from inside a barrel. Other times they tell me that I sound like I'm far away. This on the JBL tune flex earbuds.
