The QuietComfort Headphones (2nd Gen) were unveiled today and feature several upgrades that have trickled down from the firm's more premium flagship QuietComfort Ultra Headphones (2nd Gen). That figure falls behind the 45-hour performance of the QuietComfort Ultra Headphones (2nd Gen). The new Bose QuietComfort Headphones (2nd Gen) are available to preorder now for MyBose members, with global shipping from 13th August. The new headphones cost £300 / $359, which is £150 / $90 less than the QuietComfort Ultra Headphones (2nd Gen). We'll be curious to see how the two compare when we get the new Bose QuietComfort Headphones (Gen 2) into our listening rooms.
