Bose has released an update on its headphones QuietComfort35 II that adds Alexa voice assistant feature. No sooner, a new technology launches, Bose updates its software and its products accordingly. It is the most vigilant company that never lets down its users by keeping them waiting for these technological updates. If you’re wondering, voice assistant support is the main difference between the Bose QC 35 Series II headphones and the original Quiet Comfort 35 Series I. Although, the latest model lets you use the noise canceling feature in both modes, wired as well as wireless mode.
