Black Friday is Friday, November 27, 2026. Amazon’s Black Friday deals run November 19–30, through Cyber Monday, from 12:01 a.m. PT (3:01 a.m. ET) on November 19. , Amazon lists Koss Porta Pro Classic Retro 80s Style On-Ear Headphones at $39.99, with no deal badge.
Cheaper in Headphones, and what changes
Things of the same kind for at least 10% less than $39.99, with the attributes the retailers describe differently. Their words, not our judgement: we compare listings, we do not test products.
Battery figures change with the mode: Bose rates its QuietComfort Ultra Headphones (2nd Gen) at up to 30 hours in Quiet and Aware modes and 23 hours with Immersive Audio on. Bose says its gaming mode uses the aptX Adaptive codec with Snapdragon Sound sources.
