Review on Bose QuietComfort 20 Acoustic Noise Cancelling Headphones for Samsung and Android Devices, White by Max Rosengren

The Bose QuietComfort 20 headphones are just as good as the QuietComfort 25 in-ear headphones. I recommend them in noisy environments when trying to relax or concentrate. Essential for long flights, noisy subway rides, phone calls in noisy public places. Turn off noisy air conditioners and noisy neighbors. You don't get complete silence, but the rest of the sound is no longer annoying. When there is very little noise, a faint white noise can be heard coming from the headset. It's not annoying. Do not use it to make calls in quiet environments, otherwise you will lose your sense of the people around you and speak too loudly. In my opinion, the batteries last a long time and are quickly recharged. They can be charged while in use. I love the button that lets you turn off the noise cancellation and bring in outside noise so you can quickly chat with someone without taking off your headphones. It should be used when cycling or driving a car. You can wear it for a long time because the ears don't overheat like over-ear headphones do. You can even sleep with it because there are no bulky accessories on your head. . Can tilt head to one side in airplane seat. You can sleep with your head on the edge of the pillow if the bottom edge of the pillow is level with or above your ear. I don't like that the LEDs are only visible on one side of the control module. The light must envelop. Headphones should turn off when not in your ear to conserve battery life. yes it is expensive from a good headset, but without noise cancellation.
