The QuietComfort Ultra Earbuds replace the Bose QuietComfort Earbuds II. The new earbuds feature a new design with a streak of silver metal running down the stem, as well as tweaked stability bands for improved comfort and fit.
The earbuds use dynamic microphone mixing
and adaptive filters to improve call quality in noisy environments. The
microphones on each earbud work together to determine which microphone is
picking up the least wind noise and then select the best noise filter to
minimize background noise.
As for the battery, it offers up to six
hours of battery life on a single charge, or up to four hours with Bose
Immersive Audio enabled. An optional new wireless charging case cover is also
available for $49. The case cover easily slips on the existing charging case to
enable wireless charging.
The QuietComfort Ultra Earbuds will be
available in Black and White Smoke and go on sale in early October for US$ 299,
respectively
