The Bose QuietComfort Headphones are wireless over-ear headphones with active noise cancelling, a built-in mic for calls, USB-C charging and up to 24 hours of battery life. The black model is on sale at Amazon US for 26% under its usual price, well below its 90-day average of about $277. Bose is one of the best-known names in noise cancelling, making these a strong-value alternative to pricier flagship models.
