ANC has historically been a strong suit among Bose's headphones and earbuds, as we most recently experienced in our QuietComfort Ultra Earbuds (2nd Gen) review . Now branded as "QuietControl" with the release of its refreshed QuietComfort Headphones, Bose's ANC gets some key under-the-hood tweaks. Although these were built mainly for wireless use, Bose introduced USB-C lossless audio to the QuietComfort Headphones (2nd Gen). In terms of visuals, initial product pictures may not show much difference, but the 2nd Gen headphones have oval earcups instead of the previous round pads. Launching with three limited-edition colorways, QuietComfort Headphones become an even bolder expression of personal style," Bose says.
