Released in 2023 as a replacement for the long-running Bose QuietComfort 45, the QuietComfort Headphones sit as the entry-level model in Bose's current noise-cancellation lineup, positioned below the pricier QuietComfort Ultra line. Familiar Comfort, Familiar DesignAnyone who has previously worn a pair of Bose QuietComfort headphones will find the new model immediately familiar. According to SoundGuys, the QuietComfort Headphones are nearly indistinguishable from the QuietComfort 45 in terms of materials, microphone placement and button layout, aside from a new olive green color option. A Sound Profile That Divided OpinionWhere the Bose QuietComfort Headphones drew the most pointed criticism was in their default sound signature. The VerdictUltimately, reviewers have suggested that shoppers considering the Bose QuietComfort Headphones might be better served financially by seeking out the older Bose QuietComfort 45, which offers roughly equivalent noise cancellation, arguably better default sound quality, and is frequently available at a lower price during seasonal sales.
