These earphones will be able to help cancel outside noise so that you can enjoy your music in peace, although we have to say that it might be pretty dangerous when it comes to taking them on the streets where you might not be able to hear cars honk and whatnot. The QuietComfort 20 will also come with a mid-level noise cancellation feature which when activated, will allow the listener to hear voices and other “important” noises while still keeping some of the outside noise out. Sounds pretty interesting! The Bose QuietComfort 20 earphones is expected to be available this summer.
