Question about QuietComfort Earbuds - 487239

Depending on the position in which you sleep, you can keep one headphone in your ear, for example, but you have to wrap the other one to cover the sensor so that the noise cancelling function is activated. I have often been able to sleep with it when there was a lot of noise. Also very suitable on planes or buses.

The headphones protrude from the ears, so they are only conditionally suitable for falling asleep.
