Bose Touts Fit, Noise Canceling, Battery Life in Earbuds Due This Month

Bose is taking preorders for two new true wireless Bluetooth 5.1 earbuds slated for Sept. 29 availability, it said Thursday. The QuietComfort Earbuds ($279) use StayHear Max tips, said to create a tight seal, and multiple mics for noise cancellation. Multiple mics sense, measure and send noise to a proprietary chip, and an algorithm delivers an equal and opposite signal to the earbuds in less than a millisecond to cancel it, said the company. The QCs have 11 levels of control and six hours’ listening time; an additional 12 hours are available from a fully charged case. New Bose Sport earbuds ($179) have a StayHear Max tip that locks the buds in the ear, said the company. Battery life is five hours; a charging case provides 10 additional hours.
